anybody go with the 12.75" rotor up front from Coz? I read about removing dustshield, but I bolted it up to check and it seems that there is plenty of room to retain the shield. Am I seeing this wrong? So far no response from Tech forum. Does anybody know what size valve stem fits the rays forged wheels...0.453 or 0.625? ( and who designed these odd ass sizes?) I restored my new wheels and want nice stems. thanks
