Does anyone know what flares are on this car? They look like the PTG flares but for a 4 door? Thanks for any leads.

You are correct, they do appear to be PTG Style flares fitted on a four door. Since the flares are made of Fiberglass, a competent body man could cut and fit the two door kit to a four door for you on a custom basis. That's probably what this owner had done. I don't know of a four door specific kit.

I ran against this car at the SLC ProSolo. It has been worked a little for fitment. Probably a two-door kit as stated. The car also has a Eurosport TS supercharger.

At the time I saw it, it looked like the body kit was thrown on there fairly quick. Little effort went into making it look good. But, it was for function as there were 315's on the front and 335's on the rear! :eek:

It is the MA Shaw kit modified by the owner for a 4 door.

You sure thats not a truck? 4x4 action!

There is a specific 4-door kit for the E36, remember PTG ran 4-door M3 in 1997 and 1998. However this is not a 4 door kit (the 4-door kits have the front of the rear flare molded into the door so that the door can open)

Ya I realize the 2 & 4 door PTG body kits are different but where can you purchase a kit for a 4 door? And does anyone know who's car it is? Thanks

Probably a tire clearance issue with the inner fender well, which you can't touch in Street Mod.

Vis Sias' car (http://www.soloatlanta.com/results/2007%20Nationals/SoloNationalsPictures/dsc02723.jpg) has a pretty similar stance.

Thats hilarious, you can do that much modification and not touch the inner fender well.

Aren't they allowed to modify suspension points?

"Suspension components are unrestricted as long as they use the original attachment points."

Nope. :)

335s FTW :buttrock

Oh, from some suspension modifications I have seen on those cars, I thought it was free. I guess there is some "interpretation" on what they mean by "original attachment points."

Eitherway, it doesn't matter, Autox is not for me. I'll stick to my own SM rules, Supermod unlimited ;) lol

You can purchase the kit through GT Technik in the bay area, they have a deal with the original manufacture of the PTG bodywork, to be the sole distributor for the parts. The kit is not cheap, expect to pay around $10-12k.

The place that makes the stuff for Gt technik does great work. They are the ones doing my Wing assembly (Some of which is in the mail right now wahoo).

im surprised nobody commented on that huge ricer wing

Its autox, they just need a lot of drag to make them happy :)

Who needs a wing or spoiler? The two fastest DSP BMWs in the county the last two years are spoiler-les. My codriver was wondering if next year all the cars would show up missing their spoilers :)

The SM guys are all running wings these days though, right? I have pictures of Vics first version of his 2-element, its kinda funny.

Yeah they are, but they have HP to spare to pull the wing through the air. Talking to Tunnell, his wing costs 40hp at 60. I didn't get downforce numbers. When you have 450hp you can afford it in that situation.

I'll ask this weekend and confirm which kit is on the 4-door... I race with Tyler and Mike locally.

ha those are some big tires!!

Speak of the devil...

Cool car, but starting bid of $80K?

40hp at 60mph, unless he has a parasail behind him, that sounds a bit off. Maybe 20hp, but at 60mph, you would need a 4 element A mod style giganto hill climb wing to get 40hp at 60mph...maybe at 100mph it would be right, since its exponential with speed.

From the wing I've seen those guys using, they are just two big elements stacked on top of each other.

It was 2 elements IIRC, with the last one pretty much vertical + gurney flap and close to the 8sqft size limit. I wondered if he had actually done testing of the downforce vs drag numbers. It basically was a vertical wall of metal as high up and back as the rules allowed.

And since I have zero real practical knowledge of aero on a car, I'll leave it to you to decide if that setup is a 20, 40, or 400 HP cost.

August 2007 Race Car Engineering - Read and learn.

Full blown AM 4-5 element wings that were actually engineered are only producing 200lbs at 50mph (333 combined front/rear), and thats with a ton of drag obviously, about 2.8:1 l/d ratio it says.

If I had to guess, that wing setup is producing almost all drag with very little actual downforce being applied. So it very well could be taking 40hp away, but its not helping his grip at all...unless he is trying to get a leverage affect by producing a moment around the contact patch of his rear tires from the wings rearward drag force...but that would reduce his front grip.

As the speed increases though, there will be a lot more HP required to overcome the drag.

U going to post pics?

Oh my wing, yes, when it is done and on the car.

BobT wouldn't just throw a wing on the car if it didn't work for him.

Easy way to test an autox cars wings...should be very clear if they are working. It just takes a timing system and a big circle he drives around.
