I used to run Centerforce Dual-Friction on my Z6 before I put in the LS-VTEC. I would buy just a new clutch disc, you should be OK with using the F1 pressure plate!

 

Really!?!

 

I loved my center force clutch, dual friction is segmented like 6-puck (on flywheel side) and full face against the pressure plate for smooth street driving!

 

I think it is rated around ~200 ft/lbs of torque!

 

What the fuck is "featherment"? Lol... That's a sweet new word..

The center of the clutch disc will either have the hub coupled to it with springs or without. A sprung disc will engage smoother, but the springs can sometimes affect how the clutch holds in high HP applications. An unsprung disc is generally harsher to engage.

Did you get the flywheel resurfaced when you installed the new clutch? This is obviously very important, especially if you've changed clutch disc material.

If you have a stepped flywheel, did you get the step machined properly?

I don't think there is anything wrong with the clutch, it sounds like something else is causing it to not work up to it's capacity. Well, unless the pressure plate is crap and doesn't have enough holding pressure.

 

also with a 6-puck disc I wouldn't worry about break-in period either just drive it like you stole it!

 

It really doesn't like that.
Thats when it doesn't hold.

 

go with act and i would change pressure plate as well

 

you need a new clutch

 

i had the clutch masters stage 3 and i loved it.
