is it possible to mount the 2 front calipers from the FD to a rx8??? is R1 caliper/brake larger than other model? what do i have to do if i want to do this swap? do i need smaller rotors also? anyone have any suggestions will help, thanks!

 

As I already posted in your other thread in the West section -- the RX-8 uses bigger rotors than the FD, so it won't work without modifying the calipers, ala Mandeville type setup. Not to mention making custom brackets. All for what? So you can have a caliper that says Mazda on it?
