so i shift at 5.500 when raceing but everytime when i go into 4th it just makes a werid grinding noise and always delay's going into gear i think mayb the flywheel is to light since im boosted idk im thinking of getting a 12lb flywheel and a different clutch since ive seen so many prob's with the CC stage 4 it suck's because 3rd and 4th are the best gear's for me pull so nicely anyone else have this same clutch possibly same flywheel with this issue... if i shift at 6k rpm from 3rd to 4th 4get about it just does same ish and the gear's are already short enough in the tc dont wanna shift at 5k
