Thunk noise while shifting

[ChiGGz]

I have an SBR 3500 clutch w/ fidazna FW and once in a while when I shift I get this THUNK that kinda sounds like its coming from the REAR of the car, but I could be wrong. I almost always get a thunk when speed shifting or downshifting without perfect rev matches. Even when I'm trying to baby it, I'll get the occasional thunk. I don't agressively drop the clutch for this to happen sometimes and the only solution is to slip it everytime I change gears. My clutch pedal play is about 1/3 travel from the floor.

Help a fellow DSMer I hope this doesn't eat my transmission or my clutch up! Or should I not worry about this?

Please try not to chalk this up to a bad driver, I've driven tons of standard cars, including a bone stock GSX and have never had this problem shifting before.

I know this a common problem on the 1G. Could very well be your problem as well if the 2G uses the same carrier bearing setup. And since it's real easy to check to see if that's the cause, it doesn't hurt to go check it.

I just looked and that link doesn't explain how to check it. Grab the driveline behind that bearing and try moving the driveline around. If it moves, then it applies to you.

I kinda had the same problem with my 2g GST. Check all of your motor mounts and make sure they are all good. I had a bad mount and it would clunk like that too. Good luck! -Matt
