[s-cars] Ball bearing turbo

Hey Guys,
	I am happy with my clutch..but agree with Dave Dawson that if I
was dragging the car..especially off the line that she might not be the
clutch for serious "launching".  But again Dave is putting down another
55+ HP then I am...man I need to hit the dyno again.  Centerforce DF has
a stock feel and grabs great for that occasional launch across the
intersection or obnoxious spanking of the riced out Civic ;)

I have been very happy with the Centerforce Dual friction and
LWFW..great combo.

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

92 //S4
90 Cq
40 valves 'O plenty!
