Horrible bucking and shutter after clutch install - Page 3 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

So I had a mechanic from the shop that installed the clutch take a ride with me today. Of course at first I could not get the car to buck at all. No matter what rpm or throttle position clutch let off. finally after about 7 stop signs it did it about half as bad as this past weekend. His eyes got wide open and he had a confused look. I was then able to recreate it about 5 times, but of course less severe than it has been. He then said there were 2 things I could do....

1) Contact Competition clutch and try to get them to warranty it out and he would talk to the shop manager about discounted services to have it R&R'd

2) Its an aggressive clutch, drive it aggressively and see how that affects it.

Both of which are fine options, but what if they installed it wrong? I doubt Competition Clutch is going to warranty it without it being taken off and sent to them for inspection first.

ok I just looked up your stg3 disc. and that is your problem the hotter it gets the stickier it is. Its a ceramic disc if I were you I would by a stg 2 disc and slap it in there and it should fix your problem. Or just beat on the ceramic one.

I agree that they wont do a thing without it being removed. I am going to drive it harder and see what happens, then go from there
