I recently chewed up my stock rotors with some gold galfer brake pads so seeing the great deal at oncycles.com on the alth rotors I bought a set. I haven't put them on or recieved them but I went to a bike show the other night and talked to a few guys who seem to know their $hit considering their "claimed" mods. A few guys (mainly straight line racers) said that under street conditions these and other "racing" rotors, being designed for the race track will warp under these conditions very easily. I don't see why this would be true but I'm considering getting a second set of rims to set up for when I go out on real rides other than commuting. Have you guys ever heard or found any truth in this or should I slap them on and not worry. Thanks guys. I hate talking with people at those things, they all seem a little dumb compared to this forum. The only reason Im checking was 2 of the guys were running very nice and well set up zx14's LOL.
