A Body Suspension Set up
My first Mcleod Soft-loc clutch was set up by Tim Hyatt, aluminum flywheel, 10" long P.P. with an aluminum pressure ring, 10" disc. When it need to be rebuilt ( after Tim passed away) I sent it off to Black Magic, what a big difference in clutch setups. Tim's clutch was setup with more base and a little centrifugal to lock it up in high gear. Black Magic clutch was set up with very little base pressure and heavy on the centrifugal. Tims clutch set up was a lot faster tuning window than Black Magics. But once I figured out the tuning windows on both clutches the car 60' footed the same and when I ran the Clutch Tamer in between rebuilds once I figured out the tuning on that, the the car 60' footed the same as the other clutches.
Moral of this story is like Turk said SLR and clutch management is everything in the first 60 feet.
