Has anyone used or know of anyone that has used the below Racing Brakes rotors with modified stock calipers? I'm trying to find a solution to enable the use of 18" wheels for the track use w/o spending $3K+. I have access to the mill so not worried about machining down the mounting pads on the stock calipers. Mostly curious how the pads sit on the 380mm rotor (any overhang) and does an 18" wheel (like Apex EC-7) actually fit?
