Depends on your setup. You running street tires or slicks at the track? If you want the best setup, you have to run double adjustable front shocks so you can tune both sides of the damper....they both can make a difference in how the tire grips and needs to be adjustable to meet the surface conditions. For example, you don't want to run a soft compression and stiff rebound side like many people want for the street because that allows the tire to loose traction under extreme situation...the lack of compression damping allows the tire to accelerate too fast away from the contact patch and then the high rebound un-weights the contact patch at full compression, as the momentum of the car tends to pull the front tires off the ground.
Anyway, if you want a serious drag setup, then it's one thing. If you want decent daily driver that does decently on the drag strip and has possibilities as an autocross car too, then don't worry about the compression damping too much, run a reasonably high front spring rate and as stiff a rear spring as you can stand on the street. So, for example... a 450/550 would be great... a 450/650 would be even better. Run the Koni Sports front and rear and run the front rebound adjustment around 1/2 way up with the rear wherever you like it...probably start 1/2 way and leave it until you get your launch down and then play with the rear rebound a little bit to see if it improves your launch and 2nd gear shift event.
Incidentally, the 450/550 Koni Sport setup is quite standard and would make the car a great autocross car too.
Best of fast autocrosser, fast drag racer, and decently comfortable daily driver.
