preload your drivetrain when launching. that should help you a big deal. the idea is to lessen the shock load to your drivetrain. wheel hop is a bitch but you shouldn't have to worry about that with slicks. you'll have to play around with the tire pressure for sure but always check them before each run because they will fluctuate with the heat from every run. what size tires did you get? for something in the 300 range, you should probably be using 22" or 23" tires. do you have lsd? camber kit?
