I just installed stage 2 Spec clutch. The pedal is nice and soft, how I like it. Now two problems, first I get some clutch chatter in first gear and second my car now vibrates more. What can cause chatter? I think they might have not cleaned the flywheel and pressure plate properly. If those are the causes I will go back and tell them to redo the work and make sure everything is nice and clean. Let’s hear your suggestions.

 

I would get a pressure plate to match the clutch disk. Second. Make sure you use lok-tight on the flywheel bolts, and the pressure plate. Good luck
