PPF Turbo forum

Hi everybody
I am from denmark, so it is easyer to write in English
I have a question for your all
I have build a very nice BMW e30 with a m50b32 turbo engine, puts out 600 bhp at 1,5 bar boost, the car is build only for dragracing.. weighs 971 kg with me in it, but i have a problem, going Down the strip, the car losses grip whenever I shift in to 3,4 or 5 gear, and goes sideways.
I have only testet the car once, drove on m/t street 26x10,5x15 slicks, koni adjustable rear dampers, h&r 20 mm springs and no antiroll bar, strong Flex bushings everywhere, 210 welded diff
My best time was 11,7 with the tires spinning in 3 and 4 gear

What do you Guys have on your e30s with powerfull engines? which setup, dampers, springs and so on, hope that someone in here, can give me some pointers what to improve.
I have build a large rear alloy wing to apply downforce at high speeds, but havent testet it yet, anything else i can do??

Anyone???

softer springs in the rear?

m/t drag slicks and you get better tracktion.

Why no antiroll bar?
What are your wheel angles?
What spring rates?

I use touring rear spring avo shocks adjusted almost to the hardest settings.
And My car hooks up and just go away.
I have also tuned My ignition so that the rear wheel doesnt brake loose.
Mh 8.5 26 15 tyres.

I tried koni with adjustable rebound first but they didnt work out for me My car just squatted and starter spinning the rear wheels.So I bought avo adjustable insted and they worked much better.
