Drive shaft? Anyhow. Truthfully, slipping the clutch is probably more damaging than just dropping it. But think about it, a clutch is a wear and tear item. Also, some tire spin is necessary to attain a good 60ft. With my 2.1 second 60ft's, I dont think anyone here is gonna argue with me. I say drop the tire pressure down to around 18psi. First, rev to between 3500-4000 and just drop the clutch. If you bog, raise the launch speed. If you spin wildly, lower it. By lowering the tire pressure youre creating a wider contact patch, and because the tire has less air, it creates that rubber band effect that you see slicks doing. It worked for me, and I have some pretty good numbers to show for it. *shrug*
