Mine cost about the same , and like I said if I knew you were going to start producing them I would rather support a forum member than some random person.
I've looked into adding that c-pillar as I'd get the benefit of the air turbulence and, more importantly, the angle of the rear window, but it's a NLA part now
Wish I had an M3 lolSimon

Good place to shed weight.
Is this the guy and parts?

Ok guys I have quite few Air Tab vortex generators left from when I purchased it for my enclosed trailer, where would be good location to mount these on e30 roof? I mean how far from rear window? I have huge ARP wing mounted in the back.1990 e30 325is S50 swap (NASA GTS2 race car)

From my testing I found diminished results anything over 5 on the roof. Of course, I'm using my design as reference so I could be mistaken for those.Comment

When I talked to the guy selling the airtabs he mentioned the spacing of them, so I felt 7 was the a good number to max out the benefits of the airtabs.
Whats the spacing of your 5?
Is there any benefit placing any on the side of the car? Ive seen people place them on the front sides and rear sides tooSimon

Sides are helpful, but the front is really the best help
Nah, I understand they probably need different spacing than mine, just weighing in from what I saw in the CFD testingComment

The W201 16v hit the scene in '84 and started winning touring car races by '85. The 2.3L E30s at the time couldn't see which way they went...which is why BMW started developing the E30 further into what eventually became the M3. We didn't see an M3 until '87 ... and it would never have existed if it weren't for the 190E 2.3-16
There's a lot of debate about this part, but some argue that BMW copied quite a lot of the W201 design to turn the E30 into a race winner, particularly the raised rear deck height and angle of the rear glass. There are also some similarities in the shape of the bumpers, front valence, side skirts, and profile of the rear spoiler. They used the same basic engine architecture and same Getrag gearbox.
The reason I say there's a "debate" is that Benz fans like to say BMW copied the aero package and drivetrain. BMW fans say any similarities are coincidental, since they're built to the same rule book. Personally, I buy that argument for the engine: a twin-cam 4-banger clearly made more sense than a SOHC inline-six, and BMW already had the M88 head to play with. But I think Benz guys may have a point when it comes to the aero.
In the DTM series, the E30 M3 and 190E 16v (plus their various Evo versions) won about the same number of races. It's true that the M3 is the "winningest touring car is history," but that's because it was run much more widely. Benz only cared about DTM and did not support any international racing. Any time the 190E and M3 went head-to-head, they performed about the same.Last edited by Emre; 04-12-2017, 02:25 AM.sigpic

Naturally the cars would be similar in some ways... they were direct competitors released at the same time from the same country from two companies with a long history of releasing vehicles just to compete with the other.
Then the 2.5L cosworth came out in '88, two years after the m3.... And then the 190e didn't have a single dtm champion until 1992.... meanwhile, the e30 M3 already had two championships by then. The 2.3 cosworth was competing with standard 325iS, and even had fewer HP than a standard 325iS.
It's said that the 2.5 cossie was released specifically to compete with the M3.

The Cosworth 190e was built to compete with Audi in Rally, not the e30 in DTM. Rally had similar rules for conglomeration, so a road-going de-tuned Cosworth was built for the masses. The Evo I was intended to compete with BMW, but it didn't debut until 1989.Comment
