Very good wheels. They run much truer than Por-Line and are stronger than OFNA which after about 8 race days on a very blown-out rough track. The Pro-Lines' webbing became distorted after one qualifier and I can't remember how many OFNA wheels broke, thank goodness they sell them in a six pack because you'll need all six to make one set of wheels.
BTW: Until I switched to Panther I became very adept at removing tires and foams without much damage.
