I am returning my car to stock.....will stock calipers fit the rotors that come with the M-2300-X brake kit?? I know they are both 13", also what else would i need? Will lines hook up to stock? any insight greatly appreciated.
Yes on the rotors, they are the exact same. I can't comment on the line length difference between PBR (standard Cobra caliper) and 'R' Brembos.
The banjo bolt will be an issue you'll have to investigate. Two different thread types exist for the PBR calipers (course and fine). Once again, I'm not sure what thread type, banjo bolt size or length is used on the Brembo calipers.
