Jam? Are the guy racing the BMW? I am horrible putting faces/real names to these Caferacer.net handles. Anyway, I am looking for good, but reasonable price, after market front brake rotors for my 1984 R100RS. The rotors are 260mm/10.23 diameter, using a Brembo 2 piston caliper. Anyone got suggestions. I am curious to hear what folks use, especially if they race disc brake BMWs. Note: BMW forum I am on, everyone just says buy the OEM aftermarkets, which I am considering.
