A standard clutch would be fine what boost your running? Chances are you are about 200bhp at most. Maybe a stage 1 just to be on the safe side. I notice this with my clutch aswell but its defo not needing replaced. Its no where near as bad as how you make yours out though. Just notice its slightly more distinct when cold. I reckon mine is down to the slave or master being very old going to try the slave in near future.
