My car puts 450/450 to the ground. I run it on the road course pretty regularly, and on the street. Went to the drag strip once this year.

I'm using a Centerforce II kit: disc, PP, bearing. Also using an alum flywheel from Fidenza. The Pressure plate was made by Vileao (or something like that). I remember seeing the stamp on the casing.

Performance is excellent. Doesn't wear out my leg in traffic and city driving. No problems on the strip or road course. I installed it last winter with the new engine. Still feels good.

Clutches and other drive line parts have a HP rating. But that should only be used as a guide. The company figures out how much power the part can handle in the average car - which weighs 1/2 more than a Cobra. And there's a fudge facter in there, too. So if you're making 400hp, and the clutch is rated at 450, it will last just about forever.
