[135i2]

Best result is fitting the full Monty as many have done. The entire, stronger M3 cradle, diff, axles and hubs. The whole shebang is pretty much plug n play if you grab the front yoke with the diff. I tossed the M3 brakes for a big brake kit. Why would you want to keep the 135 axles over M3/1M if available? No master cylinder change required.
