OK. I think I've had this setup for much longer than anyone else so I thought I'd put my thoughts out on it.
My setup:
XTD Stage 3 Clutch + 11lb Prolite Flywheel
I bought this setup back in summer of '05 and didn't get around to installing until October 1st, 2005. The whole shebang cost about $299 IIRC. Aside from the "normal" frustration that most people get when doing a clutch on these cars for the first time, the install went along fine. I had about 68-69k on my car when it was installed.
Upon first startup it was evident that the clutch pedal was much more springy. That would be the best way I could describe it. There was a little more resistance than there was with OEM but not as much as an old time cable clutch. You could tell the clutch was beefier.
The clutch disk itself was a 6puck. As anyone will tell you, driving a 6puck takes some getting used to but I didn't stall when I first drove it like I know another member did

. Its normal for there to be a chatter when engaging the clutch slowly, if you get on it quick and go, its a slow engagement. Theres also a "whine", which is the best way to put it, that you'll get at times that other people with 6 pucks have experienced. This is normal.
At the time it was installed I was N/A modded. I was never able to get it to slip or to burn it. I dynoed out at 141whp which isn't alot but it held it fine and still holds fine. I have raced a whole bunch of times, 15+ runs down the 1/4 and of course other runs/spirited driving else wheres so this clutch has seen its share of abuse.
The car now has 125,XXXmiles on it and I still have this clutch installed. It still does great and still doesn't slip when I beat on it. I'd recommend this clutch to anyone who just plans on N/A and possibly spraying nitrous on it. I really have nothing but good to say about my experience with this clutch.
If you have any questions about the clutch/flywheel combo just ask away, I just wanted to put this up since its an ebay clutch and offer my thoughts to anyone else considering it.
