New gripforce stage 3 slipping

[kory2000pr]

I just completed my 500 miles brake in period on my crappy GripForce stage 3. So last night I downshifted from 5 to 3 to chsnge lanes and the clutch slipped real bad did a couple more runs and notice the cluth is slipping mostly in 3 and 4 gear.Stay away from Gripforce!
MY SPECS:
02 WRX with STI uppipe and catless down pipe.Stock engine management.

it might have been you break in..... 500 miles isn't really that much for a break in....i broke my clutch in for 800 city driving, about 1000 regular.

edm or jdm sti? Because...usdm 02 sti doesn't exist. Granted break in is normally 1000 miles on engines and clutches...
