TMS is building two E90 sedan racecars at our Amesbury, Massachusetts facility. We'll be adding more photos of the build as the cars develop. Check back for their progress.

Kinda like American Chopper with a lot more technical skill and no yelling. Well, not really, but still pretty cool.

Sweet! Subscribed. :eatpop:

Seems more appropriate in the Track forum though...:)

Hey Doug what's the intended class or series that it'll run in? WCTC?

Why didn't you guys start off with a motorsports chassis? Or is there no e90 motorsports chassis aside from the WTCC chassis?

Will the race cars still be called 328s or 330s? I ask because I assume that unlike the Bimmerworld cars which have the Euro 2.5L motor, you guys will use the 3.0L block.

Very nice! Glad to see a pro team finally documenting their build publicly.

When you say, "not really," are you referring to the technical skill or yelling? lol

Does Will have backup doors to his office when he punches and kicks through them during a temper tantrum?

Thanks for the pics, definitely going to be following this.

I think they need a dedicated webcam :devillook

One question: Will you be cutting into the firewall for the cage? (Hint: gac or WC ;)) Either would be great...seeing 4-5 e90's battling it out in WC would be pretty sweet though.

Judging from the fact that its a street car being stripped down and not a body-in-white, I'm guessing GAC?

nice work on the cage so far!

pardon the ignorance, but what kind of bender is that?
its doin a nice job of making bends without crimping them, looks
to keep the same diameter of the tube the whole way through.

and im guessing with a cage build, just like with a intercooler piping/exhaust build that you dont want the inner parts of your bends crimped? does it matter with a cage build?

Crimped bends are NEVER allowed in cage building...it's a much weaker bend than a proper mandrel bend.

If I had to use my secret spidey sense, I'd guess Koni. Probably, because I have built cars the same way for the same series (starting back in Firehawk). The reason I say this is that you can actually keep all of the undercoat and soundproofing on a car as the weight is exactly where you need it. Also, keeping the heater box in it is nice as you can keep the windshield really clear in the rain (plus if it's cold you can turn on the heat). The only suggestion I give is to keep the cigarette lighter and cup holders in the car. This is a nice touch as the crew can keep their cell phones charged and they can take a soda with them when they have to sit and wait through tech. I did it and it was nice. When I build the replacement for my car, it'll have those in it too.

they do have webcams. but i dont know if they have them in the room they are building those cars. theres 2 just painted ones here http://www.turnermotorsport.com/html/webcam3.asp

but i cant tell if thats an e90 or not

Those are E46's...you can tell by the location of the fuel door if nothing else.

Interesting that one of them is vinyled up in the new Turner livery but sporting a World Challenge spec wing.

I love watching yall build up these cars. and now yall have that big new location and all. i have a whole bunch of service receipts from turner from about 3 years ago when the previous owner had my car in yalls shop getting some stuff done. before i shipped the thing down hear to texas. makes me proud to be able to say ive had my beast in the turner shop

Good luck with the build, you'll see that the E90 is a great performer once you get it finished and set-up, its very fast in capable hands.

That is the car that Lucho De Castro bought from Turner after SWC Mid Ohio race in 2006. They put it back to Turner livery and we will see where it ends up...

Lucho was a close friend of mine. We had a great time getting our racing license at the SCCA race school at Roebling Road, Jan. of 2004.
Lucho, his wife Laura and their two children died in his plane in October of 2006 when his SR-22 iced up over Nevada.
It was a tragic loss, I wil miss him and his family.

I had the oppurtunity of being part of the TMS crew for Lucho on his first SWC race weekend at Mid-Ohio when he was testing the car out. He was a real fun guy and had a smile on his face that whole weekend. It was definately a tragic loss and sorry for the loss of one of your close friends.

Doug, looks great!
Quick question: Help me (noob) understand why your main roll hoop is set so far behind the B-pillar. I can assume you would have better F/R weight distribution and safety by placing the driver back, towards the center of the car, but don't you loose a considerable amount of torsional stiffness by not connecting the B-pillar to the main hoop? Just seems like a missed opportunity for some chassis stiffness.

I am sure you have some reasons for fabricating the cage that way, just curious to what that is.

Sedan. The B-pillar is much further forward than in a coupe; you can't put a hoop there or there'd be no room for the driver.

Sure you can. Our First 2 World Challenge E90's have the main hoop fully integrated into the B-pillar. It's just much easier to place it further back.

So the E90 is wide enough to fit a bar inside the B-pillar, and still fit a seat between the bar and the trans tunnel? On an E36 sedan I just don't see how there would be room, and I'd be very surprised if your seats are fully forward of the B-pillar.

Sedans have better torsional ridigity numbers than coupes from the sources/numbers i have seen...but thats kind of out the window once you have a cage thats tied in all over the place.

Well a number of reasons. One, this is a sedan, unless your driver is the size of a jockey, if you were to put the main hoop at the b-pillar his head is going to be behind it. Not good. See more below.

Second, when you put the main hoop where we did you can secure the base to three spots, not just the floor. I can take a photo to demonstrate this better if you really want, but the main hoop on our car is welded to the floor, rocker box and the sheet metal section that houses the factory fuel tank / back seat. You can't do this at the b-pillar. So this section where we went to is actually a better spot to improve tortional rigidity.


Sure you can. Our First 2 World Challenge E90's have the main hoop fully integrated into the B-pillar. It's just much easier to place it further back.

Ummm... Gotta pipe in here. As stated above, to properly engineer a cage in these cars to offer the best protection for the driver, you move the main hoop further back, not at the b-pillar. It has nothing at all about being easier.

Don't take my word for it, look at any BMW Motorsport WTCC car and where they place the main hoop.

I doubt BMW Motorsport did it this way because it was "easy."

Our main hoop is inside the b-pillar Doug. Not inside the car.

Not trying to hijack your thread so show some more pictures or something, when are these things going to make it to the track.

Got it, so the driver's head must be behind the main hoop then?

No problem. Didn't think you were, just replying to your post.


so show some more pictures or something,.

We add photos to our gallery almost daily. See link up in the first post.
