After a full day of racing they still feel good. I don't have enough time on them to say they will last any longer than the stockers but I have 3, 5 minute qualifiers and a 15 minute main on them and all is good. I really am thinking the problem lies with the crappy pos kit bearings. I am gonna order some good bearings sometime soon. Probably the avid's. Just so I don't have to worry about them.
