RS4 Clutch Slip after 4 thousand miles on Stage 1 car



Got a tiny bit of slippage under wot in high gears last night, clutch is new VAST RS4 with stock flywheel, and has new slave cylinder. Has about 4k on setup. Ran it easy for the first 800 or some miles. I launch every now and then but I have a little more often lately practicing for the track. I have let my friends drive it a few times and it came back smelling pretty strongly of burnt clutch (probably due to them attempting a launch like they would in their fwd 4cyl... so much for them drivin the S anymore) , but a few burns arent enough to ruin an RS4 clutch with just a stage 1 setup are they? i rarely burn it when i launch myself, I read on audiworld that a clutch could become "glazed" by a few bad launches but not be shot, Could there be something wrong with the SAC system? from being jolted by a launch maybe? any help is appreciated ill do some easy city driving and see how it feels.
