Rather than removing the diff and drive shafts for installation into my 335i, can I just swap over my 335i hubs and brakes onto the M3 subframe and fit the whole shebang in one go?
The complete final drive will not likely bolt up to your 335i the way the 335i bolts up, you are better off installing the complete M3 sub fame along with the M3 final drive and use better suspension arms and larger brakes.
