I bought an M3 parts car that has everything except hood headlights etc...

i'm swapping in the engine and transmission but wanted to know if I could also swap in the brakes.. not just the calipers but everything like the knuckles, hub, shocks etc...

I'm pretty sure fronts wont be an issue but the rears I was curious about. im keeping my ZHP diff instead of swapping i the M3 DIFF since id rather sell the diff for money but if I sell the diff and swap over the trailing arms, hubs, suspension.. will it bolt on? and if it does, will my rear wheels have a wider track?

thank you for any and all advice.
