well we slapped it on there right after the install. being a factory clutch made for the z06, it doesnt need that much of a break in period, so taking it up in the rpm range should be ok... just no hard high rpm shifts for a few hundred miles... getting up there should be ok. but i guess its a possibility none the less... we'll see when it gets retuned. the clutch is good and broken in now, so if it WAS slipping, it wont be now. we shall see
