Thats good. JHM blames pads and bed in process. I have owned many cars and track cars.. never had this problem. They never offered anything as far as help, and I am pretty sure they are Chinese cast rings. Might work OK in some scenarios for street, and even track, but I hate having to be the guinea pig in pad testing. They should at least warn people. Seems they know of the issue, but call it an EBC problem..
