I recently pulled the motor on a buddy's 5.0 only to find his 20K mile Centerforce DF disc to be falling apart in layers and chunks. Junk!
We replaced it with a much better McLeod.
I will be running a new stock SVT clutch. They seem to hold up great and you can't beat the price. My factory clutch has lasted 80K hard miles with 3 different Trans-X's!!! The factory parts are all made by LUK. I have always had great luck and heard wonderful thinks about LUK clutches!
The Spec is an awesome piece. And if the money is available I doub't there is any better for the price!
