It's that time again. Cold, dark early, and no track time without travel. I spent all year at the track, traveling and dreaming up cars to build and what would be super cool to play with. Now, its time to turn the dreaming into something drivable!

When I came up with this, I was on the way home from driving Chris Lewis's awesome E46 M3 CM car at VIR. That car was soooo fast right out of the box with just a good combination of the right parts - and so easy to drive. It is rare that a car is that impressive, but his is.

So now the wheels are turning - if we built this thing fully in-house, how would I do it? It is very straightforward - really an E46 World Challenge car, but with a wide open rulebook. So now all the cool stuff that we couldn't do, we can!

Unfortunately, the big stumbling block for me was time. If I built this thing, I would have to use it - we already have a building with some expensive dust holders and I don't intend to add another. I was at the track about 100+ days in 2007 in addition to running a business and a race team - a commitment to do more wasn't so smart...

But! A friend and I started discussing cars and I mentioned Chris's and that was the spark for the fire. Fan a little bit by some talk of a trip to TX, CA, etc for the 2008 BMW CR season. Now we get all the fun of building what I think will be a stellar club racing car, I have a great driver to drive it, and I get to jump in and play when time permits - win-win-win!

This project will result in a very solid car, but nothing so far on the exotic end that it takes black magic and some guy in a dark shed to recreate- no one offs allowed! The engine package will be fully based on our coming E46 M3 tuning line for street cars, including wet sump oiling. The suspension is not specially valved, just what all the companies involved tweaked through the years of racing E46 cars that is now incorporated in off-the-shelf parts. The brakes are Performance Friction, but out of their yet to be released street lineup which takes $3k monobloc calipers (per) and turns them into a $4k brake kit (OK - maybe there is some black magic involved). The chassis components will be lightened, but no widebodies and nothing wild. Add plenty of race goodies and more fabrication than you can shake a stick at and off we go!

As we go through the build process, we will post a lot of pictures and progress reports here. I promise not to get into arguments about why we did it the way we did it and offtrack into esoteric engineering discussions (so don't even ask Steve :))

First pictures coming shortly!

Nice. With this build photo documentation and Turners E90 builds, should be an exciting winter (along with my build of course ;)).

I promise, I'll be as Objective as possible ;) Sounds like it should be an awesome project, just remember, its all about common nodes and triangles!

You just better hope Akard does not get in on the project planning, he might try to convince you an E30 is the way to go.

What I really want to start seeing in projects like this are extra steps taken for safety developments. Side impact protection, new harness mounting techniques to minimize belt stretch, etc. I'll hopefully start a trend with this stuff so we can have overkill safety precautions taken, and make this an even safer hobby (and career/life for many).

I'm also very excited to hear Chris's car came out so awesome! I can't wait until the E46 becomes the new "E36"...seems like its not too far away.

I just sold my E46, so now you can build it for ME!

As we go through the build process, we will post a lot of pictures and progress reports here. I promise not to get into arguments about why we did it the way we did it and offtrack into esoteric engineering discussions (so don't even ask Steve :)) I'll get the argument started. What kind of paint are you going to use on the chassis and cage? Using the correct paint, can add torsional rigidity to the chassis. Sikkens is supposed to be able even make a minivan perform like a F1 car if applied properly. Using Glasurit on the outside gives you the slickness to make the car cheat the wind.

this should be fun to watch...remember...Picture Whores we are.....we need pics..pics....pics.....

Yohoooooooo!

My car will have a BROTHER!! (or is it a sister).

James, if you need me to come up there for my secret seam welding technique, just let me know......... Every weld has been plugged into FEA. :D

See you soon I am sure.

Sweet...I predict some epic races next season based on the fun we had at Roebling to cap off this year. If we can get Bassen and the Bimmerworld E46 in the mix, it will be even better.

Same, cant wait to watch this unfold.

Great, looks like I am moving back another spot on grid :) Wouldn't you rather build a nice KP project! Seriously, that is great news. Cars like this raise the bar for all of us.

Very cool James, I hope you will make it to Ofest at WGI.

Vince
(a few C Mod tricks up our sleeves this winter too)

Congrats on selling the car Brian! So now are you buying another or just the engine :)

No paint. We are actually going to encourage rust to thin the metal. The resulting pock marks will keep the air laminar.

Thanks guys. Will definitely be at Ofest. Once the CR Schedule comes out in full we are going to try to make a CA race with a few cars and I want to head to Eagles Canyon in TX (Everyone should make an attempt to get to TX once in the year - those guys are great!). Lots to do but with some luck, we will be at VIR this spring and hopefully not shaking it out.

By similar analysis, allowing the floorpans to rust through should reduce the pressure under the car, and also provides the added safety feature of left foot (Flintstone style) braking.

Subscribed. What irritates me is now I have to buy more race car stuff for my POS from Bimmerworld to support this project!

Keep up the good work guys!

:eatpop:

We got the car in on Saturday! The previous owner was kind enough to drop it off for us. It was a good track car in its previous life, but for the scope of our project, we didn't need a lot of the upgrades. We bought the shell and some of the goodies and the PO took the remainder of the parts to sell. Tip - you can usually recoup some costs on a racecar build by selling the stuff you don't need! In this case, both the PO and we made out quite well.

The good side:

Front:

The damage:
http://www.bimmerworld.com/images/E46CM/InitialF3_4pan.jpg

Damage close-ups - notice the door seam and fitment is still correct - the pillars didn't move. I don't like to fix wrecks and starting with a twisted shell may save some money up front, but I steer clear unless it is a real budget car. This cosmetic work will clean up nicely when it goes to the body shop:
http://www.bimmerworld.com/images/E46CM/InitialF3_4.jpg

http://www.bimmerworld.com/images/E46CM/InitialR3_4.jpg

Next step will be to figure out a few things we plan to do with the car, then strip it for fabrication. My guess at this point is that we will first dip, then fabricate, then repair damage and do the bodywork, but we will do some more extensive investigation into the body area first.

Nice, doesn't look that bad at all. I assume it smacked into a wall? Assuming it did not roll on its side or anything, other than checking to make sure the suspension mounting points were not tweaked, should make a great donor car.

So is this a full in house car, or is it a customers "free for all" project?

Definitely have to second the 'sell whats left on the floor' comment. I basically have a free uber clean e46 m3, including transmission, all body, suspension, drivetrain, etc. Its amazing what people will buy, but definitely try to package some odd parts together, it helps make a sale :)

I still have some weird parts left over, like the wiper motors, and some ABS components, but otherwise, I have nothing left. I got lucky with this flood car, Matthew Groner definitely knows how to pick em! (cough plug cough).

Keep us posted James, I can't wait to see this thing transformed.

Nice!! Looks like the car just had a bolt in cage?

Nice work James, Glad to see there are more people out there willing to put a little work into a damaged car rather than sending it to the trash heap.

I may be off the deep end, but here is my damaged project.

Man - gutsy to go after that one. I built my first E36 WC car on an $800 shell that was straight, but didn't have any parts on it. Except the LS diff I sold for $600 :) Good luck on it, it will be a fun one. Certainly call or email us if you have specific questions. I am a pretty good project planner.

Nice!! Looks like the car just had a bolt in cage?

Correct sir - gone now to be sold.

Nice, doesn't look that bad at all. I assume it smacked into a wall?

Yeah - tirewall, so cosmetically rough, but pretty soft in the grand scheme of things. It is a customer's car that has given me the control over the direction, to do it like I would want to do it. We won't be doing anything nuts on it - I intend for it to be a solid car that proves you don't need wacky one-off stuff to be fast.

haha. yeah thats the deer slayer alright. Man I didn't even know it got dammaged again. That car was seriously fast for the little stuff that was done. lookin forward to seeing the finished product.

oh and i'm prolly going to be very depressed by the times it puts down.

Yep, that's the VIR deer slayer and 10th overall at the GRM UTCC car. Capable of something like 2:07's (IIRC) around VIR Full. And almost street legal. :D

Awwwwwww. *sniff*

I'm sure going to miss the hell out of helping that car's previous owner turn wrenches on it. Well, more accurately, handing that car's previous owner wrenches while HE turned them, on it. :D

Best of luck with it James!

Go James Go.

I decided to just replace the engine on the OLOA car for 2008 because of time constraints. All it needs is more power so get the E46 engine upgrades done and then if the $$$$$ are available maybe I can get mine done in the fall of 2008.

Kimmelshue's car? What the? No wonder I haven't heard from him...hopefully he's stepping up to a full-on racer. I'm sure he was OK, but sorry to see it...:(

There are CDOC stickers on a lot of the SE30's. They offer contingency money for running the stickers.

I don't know why more GTS guys don't run their stickers too, I think the contingency money is available for them too.

Taking jabs at our car huh? :D We're already preparing the "Akard defense" for next season...disadvantaged technology.

Why not just strip all those custom parts off the World Challenge car? :stickoutt

"Does CDOC still have the MS chassis hanging...?"

No, Colin sold it to Turner, now Turner has it hanging from his ceiling....

LOL - no way. All the top running Mod cars in the field are pretty tricky in certain areas - and I am not taking a jab at any of them :) But our V1 car won't have anything crazy. Certainly will use some WC technology, but then again so does every club car we prep in some way or another.

I would...major aero advantage since BMW CCA limits what you can do with the splitter to in front of the axle. I think there's a similar piece for E36's on Real OEM, but I've never been able to track one down.

Is the heater core staying or leaving? I'm trying to figure out what to do with mine.

Thanks Brian. My chassis didn't have one and I was curious if it was worth pony'ing up $400 for since I don't plan on building it for CCA use.

How much does it weigh? I've heard 10-35lbs. I've been contemplating removing it, but then I loose the defrost feature(which would rarely be used), and I don't know what to do with the coolant lines.

Ah, gotcha.

Well, if you wanted Rolex, WC (basically stock), or ALMS (or old rolex gt style) "gtr" E46 stuff, molds are there ready to be made into some gorgeous stuff. This place was one of PTG's main suppliers (and now owns all the molds).

Have you mentioned Bosch MS M4 ABS to the customer at all? Only a couple grand more and it's supposedly a lot better than the OEM street programming (and the CSL programming for that matter), plus its user programmable on the fly.

Nope - not 900 Series trick. There is a budget and while those are stellar, I feel pretty good about the package without them :)

I have a buddy. Will be using stock ABS parts, maybe a little hot-rodding. Remember, the goal of the project is for the car to be reasonable and have firm roots in the street car it came from. Stock computers all around.

**UPDATE**

Somehow the driver got lost and the shell ended up in CANADA!!!

.......

Bad news for Bimmerworld, good news for me. :buttrock

LOL...congrats on your new paperweight!

What this stuff?
http://www.bimmerworld.com/images/E46CM/spagetti.jpg


haha. yeah thats the stuff. have you thrown it on a scale?

Waking up to find your shell on the way to be dipped and your $1k carbon roof safely tucked away - even better :) (no hammers were harmed during the removal or stripping process)

http://www.bimmerworld.com/images/E46CM/shell.jpg

James... Quick, dumb question here... In order to load and move the shell do you guys just have a group lift it and move it? Or do you use dollies?... or something else? Do the "dippers" need some kind of rolling apparatus?
I can't decide whether to use the forklift, a group of people, fab up crossmembers to bolt to my dollies, or what...
Stupid, but annoying decision.
TIA... Excellent work, as always!

Magic levitation... you can see some of it in that picture above the car.

Magic levitation... you can see some of it in that picture above the car.

I better get back to my telekinetic training, then...
:)

The dippers apparently use a group lift. We do group lift or rollers. Furniture dollies can be had at Lowes for about $25, or we have rollers that we made to go under tires that can also be tossed under a corner of the shell.

have you thrown it on a scale?

It's 52 Lbs including all the power wiring.

The frame isn't that hard to move around...it can be dragged by a couple of people if needed. I used 2 plywood platforms with three 5" pivot wheels on each; overkill for the just the shell but perfect for an entire car.

wow. I pulled 26 lbs of wire out of my e36 the other day but alot of it was already pulled out.

James, what is the name of the dipper?

Carolina Chemstrip. We were set for a 1 week turnaround and then 4 cars came in the day before we dropped ours off. Finally done as of this AM!

Those PFC's deserve some Tilton 900 series :)


Apparently I was mistaken - 900 on the way! :redspot

Nice. You should get much more consistent modulation (i.e. brake pressures), as thats one of the big advantages. Since the 600's are rarely setup properly, thats a source for a lot of inconsistent brake pressures.

900's are basically on a build to order basis now, very low production, but they are worth it for this caliber of car. Tilton told me as long as I setup the 600's properly, the advantage of the 900's is not that much, especially for club racing application. But if money was no object, it does make things a bit easier.

OT (but OnT), I am 95% finished with my pedal mounts, V2...V1 did not come out good enough, so I simplified the design, much better now (pics tonight).

James, did you also have the chassis nuetralized? The biggest issue is instant surface rust with those acid dipped chassis...all the small crevises get full of acid, and eat away surfaces that are coated from the factory that paint sprayers can't reach.

Maybe get the chassis dipped in primer?

We have 900s on the WC cars and I can tell you the consistency is much better than a proper 600 setup.

Neutralized - yes. Still will have to hit the crevices after fab.

I was just quoting what Tilton Managing Engineer has told me. I have not used the 900's, only 600's. But I've built pedals from scratch for formula cars, and its pretty amazing what some small adjustments can do in terms of ergonomics and consistency.

I also like the pivoting MC's, although I have yet to test the tension "pull" type MC's yet, I've heard good things since you are in full tension and its a more consistent compression...but damn they are expensive. You're talking 2-3k for a pedal setup, plus fittings, controls, etc. The pedal pad mount is nice too, i'm going to have to weld on a small tab to the gas pedal so I can heeltoe easier.

I'm going to make an ABS floor pan with a small molded section for my heels, i have to see how it feels, but it should help ease the pivoting action.

How are you planning to get in between the layers of of sheet metal that the acid removed the coating from?

AP also has a nice new 2 pedal push type, very simple, very precise.

So what the the typical "improper" setups that people do? I have a set of 600s on the way (3 pedal floor mount) as 900s were out of the budget. Is it as simple as ready the directions and not being an idiot or are there some tricks?

build thread coming...

Specifically what we're really referring to is the precision of the bias bar adjustment. Many times if the bar is not adjusted properly, it will give you inconsistent forces, in regards to front/rear bias.

Unless its really bad, you won't be able to tell easily without using front/rear pressure sensors. After looking at a couple hotlaps you should see if you have an inconsistent braking force.

As always, if you follow their procedure and setups you should be fine, but its the execution of the guidelines thats key, obviously.

If you have any questions, or find out from data you do have some inconsistent bias, give Tilton a call, they are good with support.

Thanks. I thought that might be the issue. I've seen may setups where the bias bar is skewed one way substantially as if someone was trying to solve a major bias problem via the adjuster rather by than MC size. MC size testing is on the list for the early season, assuming the car gets done in time ;-)

What calipers are you using? Tire size?

I bet you should end up with the front being 1/16" smaller than the rear.

What calipers are you using? Tire size?

Calipers are being spec'd now but are a secret for the time being ;-)

Tires are Hoosier bias slicks on a 15" rim, 23" diameter, 9.2" treadwidth.

I bet you should end up with the front being 1/16" smaller than the rear.

That's where I'm guessing we are going to start, but it depends on how the piston sizes come out of course. We'll probably get a range of MCs for a day of testing at ACC.

Um, ok?

What class is the car for? Any other specs?

Also, What vendor are you?

Smells like bacon actually.

Geez, be offline for a couple of hours and all of a sudden your a tuba player from Cal State Long Beach ;-) Now that the Fed is done with their announcement, work should be less busy so I can actually respond.

Anyway, to answer your questions, the car is an E30 M3 being built for GTS/3. The motor will like be a stroker M20 <gasp!> in an effort to take advantage of the power/wt rules and because I have a lot of M20 parts sitting around. S14s are not torque monsters and expensive to fix ;-) A build thread should hopefully be up shortly with more detail.

I've partnered with Jack Money at Elephant Motorsports, hence the vendor tag. I just hadn't had the time to update my sig.

And for the "pro racer" question that James asked as your proxy, no I'm not a pro racer ;-)

Hey James--Its been a long time since back in the day at Roebling. Are you going to be in Boston this weekend?

James, what are you guys doing with the oem chassis harness? I'm in need of one for my E46M3 project...

James, what are you guys doing with the oem chassis harness? I'm in need of one for my E46M3 project...

I think we will need to cut some stuff off of it - we are using the factory ECU in this project with our new line of S54 tuning parts.

OK, finally! Back from the dipper. We opted not to go with the protective coat - trying to get the fab done and this moved out to paint (Bassen and Ross, there!) as quickly as possible.

WOW! Now that's a clean car.

All those hours with a chissel and a crud wheel, and I'm not even close to this.

This Canuk is green with envy...

Nice work James, looking good

great read- subscribed.

Thanks for putting forth the effort to keep it from rusting. Can I get fingerprints of the guys, so I can match what's on the car, when I get it to paint? :) Steve

I have already told them that if we get rusty smudges, everyone here will be fingerprinted and sent to you for a talkin-to.

Hey Steve...let me know when you're going to paint the car. I wanna mix some lead dust into the paint before you start spraying. I suggest at least 10-12 coats of paint for this one. :)

We weigh our shells several times through the process. Believe me, we were pretty hot with the 40# of paint Steve laid on last time - until we found the lead block he hid underneath :D

10-12 coats sounds pretty standard for Bassen :stickoutt

Just make sure he does not cover all the small holes with lead plates and coat them in puddy ;)

Did you already get that side damage fixed?

Chris

I was pretty stoked about the 11# he added in a full 3 color paintjob and primer on our last car. If your car gets painted one day, we can compare numbers :)

Did you already get that side damage fixed?

Chris

Not yet. It is cosmetic so we didn't need to get it fixed before fab. Easier to fix after dipping as well.

Paint? Why would I bother with paint, my car is already painted from the factory.

how much does it cost to dip the chassis?

1400 for a bake and dip.

I assume $1200 for you all to get baked, and then you throw it in the acid for $200?

:)

1400 for a bake and dip.

Wow, that's pretty reasonable. I was quoted nearly twice that here in Chicago for an caustic based dip, hence the reason that I took the car up to a place in BFE Wisconsin, that was more inline cost wise, but slow.

It should finally be done today or tomorrow and if it stops snowing, maybe I can pick it up...

Well, real work begins tomorrow. One of our young employees spent the day putting on a surface prep that will prevent any rust from forming in the short term. Marks went through it with a pen today and marked all the spare metal that BMW included. Tomorrow and about 1,000 spotwelds later and we will have another chunk of weight out. Anyone want to wager on the drill-through percentage on the spot welds?

James, curiosity here...

For the average shmoe who can't moved things through a shop as quick as you guys, any reason that you wouldnt want to do the stitch welding and metal removal pre-dip? Sure, it's a large waste of time in terms of cleaning all the seams before welding, but it would probably be worse to have a naked chassis sit in a garage for a month or more before priming.

Metal removal - no. Stitch welding - yes. When you stitch a production car, there is often a lot of seam sealer or paint between the seams where you will never get to it. When you try to seam weld and the metal gets glowing hot, this stuff gasses and pops your work - hard not to make it look like junk. There is a coating the dipper can put on it to seal it up, but from memory it is nasty stuff and likely worse than the potential rust.

8.6%

Keep in mind our percentage on the E90 builds was under 1 :)

Well what kind of spot weld bit is he using? Is it spring loaded?

Please keep the thread on topic.:alright:devillook

I didn't bring it up ;) lol

Are you using the 300 series adhesive from Lord for the roof?

Initiation over.

I've worked with both fusor and duramix, both have a formula proper for carbon/fiberglass to metal bonding. I can't remember the exact fusor # right now I'll have to look for it. Call your local paint store and tell them the scenario, they'll point you the right direction. Either way both require a purchase of the "special" gun being it's a two part mix. I would also opt for the medium to slow set formula so you have time to adjust and make it all around the roof before it hardens. If not, you'll be setting the roof on a hardened bead.

Yea, I call them Swizzle sticks :) They are pretty psychedelic to watch as you slowly press the trigger and the two components mix. We actually had a color chart I think to verify the mix was complete. We got a box donated with the material from Loctite. That stuff is expensive (well the stuff they gave us anyways). Maybe I can get some that was left over...hmm.

Our stuff normally set in about 60 minutes, cured in 24 hours, but we usually created an oven around the chassis (formula chassis, small) so we could cure it in 3-4 hours instead of 24 hours.

We used hexcel nomex core carbon faced panels (floors of 747's), formed into a 3d structure, and bonded both directly to 4130 and we also made sheer panels, b/c the structural adhesive likes shear and tear. Again, the strength of this stuff is amazing. We put a test peice in the Instron and the carbon delaminated before the adhesive showed any signs of weakness. I think in one test we actually got the metal to deform!

But yea, so clamping as much as possible, with some self tapping sheet metal screws where I can't reach, sounds good. Thanks!



James/Paint/Bassen, what are you guys going to be painting the bottom of the car with after its seamwelded? After I get all the pieces done on the bottom of the car, I was thinking to get a quick spray of atleast primer or maybe something you know of that can be there for good. Thats a big area with lots of welds to rust quickly, and I figure you know best. Thanks.

There are urethane paints, no clear needed, that's your best bet. I'll go ahead and tell you that they are messy. You need to protect anything that you don't want paint to stick to because the stuff gets airborne and sticks to whatever it lands on. It will also travel through the seams so you'll need to tape them all up. How experienced are you with painting?

Are you talking a permanent single coat, or just something to get down so it won't rust? or Both? I guess i'm looking for both, and something that is durable to withstand being on the bottom of the car...although the bottom of the car is getting some aero work, so it won't necessarily be fully exposed.

Not a paint pro, but have done the normal stuff.

Urethane sounds heavy ;)

Whats another alternative you would suggest? I would prefer something that does not get airborne and stick to everything, as I don't have a paint booth...although I could roll my rotisserie outside and put up a temporary enclosed car port around it to keep wind out.

If all goes as planned, you will have your paint answer in a few weeks Steve - it will be pretty cool.

Sweet, thanks.

I might need to know in a week though, so if you could, get your guys moving lol :stickoutt I'll see how it does this week once I start welding, if its not producing any surface rust, i'll wait or maybe just throw a quick layer or aerosol primer on.

The epoxy paint (I'm pretty sure he said it was epoxy based) Bassen used on Watts chassis looked fantastic, and it holds up like a tank.

Oh, and any new pics?

Powdercoat. I haven't been in the office = no pics.

Ah, interesting. Its not too heavy for you?

Have you looked into powder paint? Its similar, but can weigh quite a bit less.

Can't wait to see how it comes out, don't forget to take before/after and "progress" weights :)

I definitely had a good 15lbs of dust from undercoating this weekend.

Playing today - zero spot weld drill-throughs to date...

Underhood metal removed mostly - PS, notice the darker color of the high strength steel sections, pretty cool!

Hi James.

For the past 4 weeks, our own "building team" has been debating if we should keep or remove the reinforcement that resided right in that area. Seeing that you guys removed it is a sign that it is perhaps not that much needed. Our own e46 will have three reinforcement tubes to each tower.

They add some stiffness on a street car, but a 1.75" tube is likely more stout than stamped sheetmetal :)

James...you are going to have a heavy car if you don't drill through all the spot welds. They are called Speed holes, lighter is better ;) lol

James...you are going to have a heavy car if you don't drill through all the spot welds. They are called Speed holes, lighter is better ;) lol

Yes, but there are only a few materials specialists in the US that probably know exactly what to fill the holes with for the right balance of weight and strength. I figured I probably just shouldn't mess with it.

Materials specialists? Sounds like someone in in the navy.

As far as holes on the roof lip, in actuality it might be beneficial in the big picture, b/c it gives a surface for the adhesive to grab onto. If you notice on some panels that are adhesively fastened together from the factory on other makes/models, you'll see these types of holes in spots. So all in all a couple holes won't hurt. There...not you can stop with the hole BS ;)

Do you guys have a rotisserie to do the seamwelding, or are you just doing it on the lift?

What are your plans for the Apillar? Anything creative after that long post by Osborni?

I guess this means he needs to get ahold of some MightyPutty. That's exactly what they do in the commercial. Slap some of this stuff between two aluminum plates with big holes drilled through them and you can pull a Semi! Besides, it's Billy mays approved and who can argue with that.

We had some last minute changes thrown at us on the WCTCs. We aactually have done some work on it, but no time to document - I have been busy.

Finally getting some work done. Initial pictures of fitting the main hoop in the car:

The fit on that main hoop is sexah.

Is the main hoop going to the floor or on plinths?

Floor.

Nice, hoop looks great. Are you going to even need to gusset it, or just weld right to the unibody?

Also, with the main hoop right there, do you feels its necassary to have that roof support, considering its going to have the carbon roof bonded on? Thanks

Thanks Steve. Mostly welded to the unibody - stronger that way. No, I don't think the roof support is necessary, but the rules regaurding the carbon roof in BMW CR require that it be installed as stock - oh well...

More updates - getting the driveline fitted - one of the projects we have to get sorted out before cage building can start full speed.

Cool. Any chance at all the car will be ready for VIR?

If it doesn't, I am going to blame it fully on Bassen... Less than 2 weeks and the chassis is barely started - no way. We want it done right and with the other projects going on, it is taking a little longer than hoped.

I'm glad you brought this up, as I think it requires a clarification.

It states, "Chassis which have alternate OE roof panels may use any of the OE panels or exact replicas. The roof must be installed according to factory specifications."

Where can I find the exact factory specifications that are for the Carbon roof installation, and how they affect the roof?

The cross brace obviously does not help over what the cage main hoop does.

If it has to be installed according to factory specifications, that would technically mean we need to know the exact attachment method for the structural adhesive, how much to use, thickness, etc.

I got donated a special applicator gun and structural adhesive from Henkel (loctite), but how am I supposed to know if this meets or exceeds BMW's factory installation (or anyone for that matter)?

The cross brace obviously serves no purpose in a racecar with a cage, and if the roof is bonded in properly, it will definitely not need any of that bracing for support.

So I am basically looking for the factory specifications, so I can know what to do, because I don't have any assembly instructions from BMW, maybe you have some documents?

Interesting, are you lowering it as well and making a tubular front subframe to get it to fit? I have some pics of the GTR for mounting the V8's (both 4L and s62), pretty cool to see them very low.

Custom driveshaft is needed I assume?

Balancing the urge to make full custom parts with the design requirement of not being too wild. Lowering minimally - still retaining factory subframe and oilpan.

Hey James...it's no longer a "custom part" if you just suck it up, produce 1000 of them and stick them on the inventory shelf in the shop. :stickoutt

Actually, leave the custom parts off...I've already seen the potential of the E46 chassis with even stockish parts and it's plenty fast. Looking forward to ya'll getting this car out on track. The front of the Mod field is starting to become very competitive over the last couple of seasons.

Here is the main hoop - welded directly to the car B-pillar, no gusseting needed.

That's extraordinary. :buttrock

Whoa. Serious build James. Looks awesome...as usual.

must

update

LOL - the rust inhibitor we applied is doing a stellar job. Lots of stuff to turn around quickly here. Should be back on tash next week (while I am at One Lap, so no updates...)

Funny, How paint guys always try to give the best advice, when it's for their benefit. Thanks James, Steve

So where's the update? :)

Headed to Wkins Glen this AM to cap off my 5 races in 7 weeks (plus One Lap). After this, the schedule calms down and we get back to work in the shop - I promise...

OK, finally! 5 races plus One Lap in the last 7 weekends. But now, we have a break. Finally getting cracking on this thing again. Basic 6-point cage is almost in, then we start fleshing it out.

I was making fun of myself, how did you take offense to that? :stickoutt

Lift is being installed in the morning, that should help things go quicker, but i've still got a long way (plumbing & wiring mostly).

I'm having a problem getting my rear wheel bearings out, damn halfshafts are seized in there.

Is that a wrinkle finish on Seth's door?

It's the same theory as the dimples on a golf ball...:lol

Kidding...

Tools of last resort - air hammer on an N2 tank with a lot of pressure and finally the 20# sledge and large punch held by a willing assistant (with channel locks if I am assisting...)

Seth's car has a run in the paint - it is kind of an optical illusion.

I can't seem to find a decent paint/body guy either. It's amazing the way some of these guys just throw paint on a car and call it done. :devillook

chip has a guy that can take care of that... :D
