The M3 uses wheels with a different offset to get a wider track. Using spacers basically achieves the same goal.
The supension components of the M3 and non-M are very similar from the geometry, with the M components being higher quality, made of aluminium vs steel, and with firmer bushings.
Yes sorry didn't ask the question very well.
If the brembo discs are +40mm over the 335i so + 20mm on radius and the Brembo calipers are thicker. I was asking how could they fit within a 335 wheel?
