I have the leaflet in front of me,and it states..Break-in.All centerforce clutches require a break in period of 450-500 miles of stop-and-go street driving before applying full engine power.This period is required to properly seat the disc with the pressure plate and flywheel.
When I installed mine,I put about 200 miles on mine before I started to race it at the trackNo problems so far.Giver s%&T!!!
