The clutch!!! I know it's a big secret still, but the 5 or 6 disc small diameter 6 inch clutch is still where the tune is at. KB racing were the first ones to have it, not so much a secret any more, but a tuning nightmare. They don't have to cheat, they just have to out spend. A $50,000 clutch combo is nothing for KB racing. But this is old info anyways, right??? !!!
Snap your neck, mega G-force launch, is all I want!
