I've had a Centerforce clutch in my Mustang for upwards of 25,000 miles so far with no problems. If you break it in correctly there should be no problems with premature wear.
If I remember correctly, Centerforce recommends 500 - 1,000 miles of easy driving, preferably city driving, with no hard accelerations for a stop and slipping of the clutch either. In any case, I am pretty convienced that Centerforce makes the best clutches money can buy.
