I just rebuilt my m6 transmission and did the spec 2 upgrade. My transmission shifts fine while regular driving and shifts below 6k rpm's. I raced the car this weekend and when I tried to shift into 2nd and 3rd at high rpm's the transmission didn't want to go into gear. I've read alot about running synchromesh to improve shifts and doing the "drill mod" to help. My centerforce dual friction clutch seems to work fine. It seems like a lot of people have this problem so I'm hoping you guys can help me out here.

It might be your clutch that's giving you problems. I've read the weights on the Centerforce get stuck at high RPM's, might want to look into that.

Mine did that with the stock shifter, felt like it was hitting a wall. Fitted a MGW shifter & all was good again, infact it's brilliant.
