Sorry Jase, just saw the post. The rotors fit in fine. I bought calipers and RDA rotors but the brake lines didn't come in the box despite being included
Everything fitted fine including the rotors but the rear brake lines required braided lines to fit. Maybe be with R34 brake lines it can be made to work??
I should clarify, the BMC is the same size as the R34. The inlet and outlets on Nissan BMC's can be slightly different which may get them different part numbers.
