Supposedly it needs NO break in, and the clutch is too new to know for sure. I would just go easy the first 500 miles just to be safe, but it shouldn't matter THAT much. Grab and GO!
go for broke. I did and no problems so far. about 1000miles on it so far. I drove 3 miles at 45-50mph then romped the hell out of it and have every since whenever I drive the car. others have put it through more abuse and track launches with no issues.
