the stock shifter is terrible, it would also help your shifts a tremendous amount is if you got an after market clutch master cylinder. I just bought a JHP billet pro, i haven't got a chance to install it yet, so i couldn't tell you how sexy it is. You have to use loctite on the bolts on a gmm ripshift, they come loose.
Do you have the rip shift? I drove one with a rip shift and complete ls7 clutch assembly setup and it was amazing.
