[s-cars] Ball bearing turbo

[Emre Washburn]

Jim,

Cody Payne runs a Centerforce dual friction clutch, as do I. He showed
a corrected number of 399whp (IIRC) a few months back, and I've never
heard of him having any issues with the clutch as of yet.

FYI, just today I ordered a replacement Centerforce dual friction kit
as something odd happened to my pressure plate yesterday as I was
driving, and when we took the tranny out, we saw this:

I'm sticking with Centerforce because it's been proven by a bunch of
listers, and I never had any problems with the clutch before
yesterday. Summit Racing is drop shipping it to me from Centerforce (I
ordered the LAST kit they had in stock) for $360 ish, next day air. I
also don't plan to go any higher than Cody has with my car.

The clutch was 4 years old, and possibly had 60k on it. The clutch
disk still had 2/3 meat left on it. Woould you be using
