Generally, give your back suspention a pretty soft feel, increase the suspention a few inchs in the back as well. This will help the car Grab during the start. Next lower tire pressure by a few psi's nothing major. You do want to increase the anti-roll in the back, not alot tho. These things should all give your car more grip on the pavement, also move the distributor to around 30-70 with 70 at the rear.
