Here's the deal. I had a drift event to go to, clutch went out about 5 days before the event. I order a replacement disc (Comp Clutch stage 4) figure I don't have time to have flywheel resurfaced, and figure my pressure plate is fine. Replace disc, clutch and PP have numerous hotspots from clutch kicking, but I have no time so I throw the new disc in regardless. Drive about 200 miles before the event, then proceed to beat on it. After about 3 laps, clutch starts slipping again. My questions:

1) Did not resurfacing the flywheel and PP kill this brand new clutch disc?
2) Does the friction material "glaze over?" If so, how can you tell?
3) Is there any way to roughen up the friction material so it will grab again?

I dropped about $130 on the replacement disc, and I know the phrase do it right or do it twice. Yes I am doing it twice, but do I need to buy a whole new disc again? I'm having the flywheel and PP resurfaced, but if I have to buy a new disc I might as well get a fresh PP as well. Thanks.

many problems. You should ALWAYS resurface flywheel, because that is most likely why you are still slipping. I'm not sure, however, if it ruined the disc, you might get away with just replacing the PP and getting the flywheel resurfaced, but I'd get another opinion on that one.

I cannot answer your second two questions though, sorry.

Thanks for the response. I know I should have resurfaced the flywheel, I was just pressed for time and figured I could get away with it. For what it's worth, this disc has less than 300 miles on it. I blew a head gasket at the track so the car was towed home and hasn't been driven since. I'm thinking I can get away with resurfacing both flywheel and PP but wanted to make sure before I put everything back together just to have to take it all apart again.

If it were me, I'd at least buy a new PP as well as resurface the flywheel. Then get a concrete answer on the disc, don't wan't to be breaking it all down AGAIN ja know?

buy a new disc, if its hazzy looking like its got glass on it almost, its glazed over. You can scuff it but I doubt it will be enough, resurface the fw/pp.. I did my lightened fw and was planning to re-install the used pp/disc, but once it came out I decided the pp had a million little hot spots and the disc was looking beat, under 20k lol took the clutch kit to autozone and walked out with a brand new one..

Yeah, I probably should go ahead and get a new disc and PP while it's all apart. I might mail them both to comp and see what they say, if they say the PP can't be resurfaced and the disc is shot then I'll just order new ones. The disc is very glossy, looks like glass.

I'd do the white bunny setup and just go get it from Advance for like 150 bucks, but I like stiff pedal feel and I'm not sure if the white bunny can hold 300-350whp.
