|I have a stage 3 xtd 6 puck. oem throwout and pilot bushing.
I do like these clutch's hold well and are sooo soo cheap haha.
Anyway, I have developed a slight squeak when pulling off in 1st gear or reverse.
None of my other cars had this problem, I hear folks with ACT clutch's also develop this problem.
This will not make me want to switch from 6 puck. After they are broken in they are great and I enjoy them. I have no chatter.
Go full face if you want to not deal with weird noises from clutch -haha
Chatter is usually an indication of a clutch that was not broken in properly.
