My 2 door E3 racer now hammers along. I've got roughly 300 RWHP from a Group C built M30B35. Car weighs 1230kg. Running, I believe, 650lb front and 350lb rear on blistein sports shocks. 15" wheels.

Car bounces through tight corners and I can just not get the power down. This is not a wheel spin issue. I seem to be flying a bit.

Where should I start in getting the spring rating right? Any good references??
