I just installed a SPEC stage 2 clutch, and the clutch shudders really bad during disengagement. I was wondering if anyone elses does this? Is it normal with a kevlar lined clutch to do this? The reason why im asking, is because I didnt have the flywheel resurfaced(i know, im a dumbass!). And I wanna make sure that it isnt the characteristic of a kevlar lined clutch before I take it all apart again.

 

I have a Spec stage 3, sprung 6 puck, with the lightened pp option, and i also cryotreated all the components. It initially made an odd whining noise upon slow engagement, but has since went away. Haven't had any problems.

 

I had the 4 puck sprung and never had any problems or noice. I didn't eve resurface the flywheel.
