With my Competition Stage 4, it took about 2 weeks of driving back and forth to work (~400 miles) to get the clutch to fully break in. I only really got on it once about a week after I put it in and it held fine, but I was never hard on it from a stop or between shifts. Now it holds great, and engagement is really nice. I still haven't launched with it yet though.
