I have a E60 530i, and I asked my mechanic if the complete sets of E60 M5, front engine sub frame, with all components, brakes, calipers, control arms, etc... and the rear subframe also with all the components were compatible with my 530i and he told me that it was, but now after I purchased he's telling me that they are not. Anyone mind helping me out here?

 

go to realoem.com. enter your car, and write down the part numbers. go back, enter your car as an E60 M5. cross reference the part numbers. if they're identical, they'll work. If they're different, you'll need to do further research. as far as i know, the brake components are a direct bolt on, but I could be wrong. google is your friend. good luck.
