Just for arguments' sake, and for temporary transportation only I have one more brain teaser:

- Would the front struts off a 325i (non-sport suspension) fit an M3?
- I realize the alignment pin on one strut mount will need to be shaved off.
- The M3 front coil looks more compact.

I am worried about clearance issues between the wheel and front struts.


Just to clarify: 325i suspension --> to M3

You could use the whole 325i strut, spring, and hat assembly on the M3. I'm not sure about change in clearance to the wheel, but with stock wheels, it probably would not be a concern.

To update my question above, YES - a non-sport 325i suspension will fit on the M3. This was for temporary transportation ONLY.

BUT, both rubber bushings ended up popping out of the RSMs, and I essentially completed the last 20mi of my trip home on only springs in the rear.

My obvious assumption would be that the non-sport rear springs were a bit too tall for the RSMs to handle.
That, or the 14 year old components just couldn't take it anymore. Once the first RSM popped, the 2nd was due within minutes.
