I have an '02 z/28 that I race in a quite a few unprepped track events and what not. I'm curious what are the guys that are racing in unprepped events an street racing doing on the suspension to get it to bite more. I can go to any regular prepped track and 1.44 60' off of the trailer, but these unprepped surfaces it MIGHT 1.7-1.8 if I'm lucky. Usually I lay out vht if allowed or pimp juice also. Suspension is as follows on a 275/60/15 Mickey pro radial:

Umi tubular tunnel mount torque arm (adj)
Umi tubular control arms (single adj)
Umi tubular panhard bar (single adj)
Umi tubular sub frame connectors
Bmr 1" lowering springs
Spohn drag sway bar
QA1's 12 way adj on all four corners with drag springs up front
