Need some advice/info on a problem I have been having. Car is a 2002 z28 6 speed makes 450 hp and has 53k miles. At about 50k to 51k a centerforce dual friction clutch was put in as well as getting the flywheel machined and geting new slave cylinder directly from gm, I also put in a mgw shifter. Now the problem, occasionally I will be putting a heavy load on the car if I'm racing, usually on the street and sometimes I can't get it into gear. Usually happens with third, it'll just stick and won't go. Now today at the track it happened twice. First and second runs. Tried getting into 2nd gear wouldn't budge then next run happened with third. I know these shifters are pretty tight and stiff but what could be the issue. Synchros? What? Thanks guys!

If it goes into gear fine with the car off then it is a clutch/hydraulic issue. I personally believe it is that Centerforce clutch, they have been known to not go into gear at high rpms. You made need a shim.
