They have been in for a year so far and I would guess 7-800 street miles so far and a few dozen track passes......no issues so far that i'm aware of. Obviously I would think for someone to even consider a pro gear they have a pretty healthy ride so I doubt that you would see 5 or 10 thousand miles a year on them. I even know of a friend that ran them for drag week and didn't have any issues either.
