you want to preload the suspension for drag racing. This will make your wheel travel minimal. It depends on where you have them now,If they are in the middle start by pulling the wheel backwards,if that dont work go the other way. I did this along time ago to my roommates EK and i got it to where the ASS end of the car would sit down and no tire spin. It was pretty good for first gear rolls. This wasnt on no single cam either.
