Although it looked like the BMW E46 M3 strut brace would fit a
non-M E46 we didn't know for sure.
At Limerock Saturday, I set one in place over the area where it goes on a 328ci, and again it looked like it would fit.
Today, parts guy Paul McLaughlin installed one on a E46 330ci and he called me saying that it fit. He sent the following pics.
Paul still has the best deal on these, so far.
Soon (May 4th maybe), I'll be installing one in my garage on a brand new 2002 330ci someone is stopping over with. Will be checking clearances, recording the amounts. Will be posting some detailed pics along with the data soon after.
