I got the clutch last November. I'd say less than 3000 miles on it. All I've noticed is that the car will rock forward slightly when I rev it way up (above 6K RPMs) with the clutch in, usually in first or second gear (haven't tried it in any other gear). Believe me, the clutch works great, as I can actually spin the tires now, as opposed to the old clutch, which slipped forever. Hunter
