| So, you are hell bent. I can appreciate that.
Here's what I think. The E46 has much larger flares (even in non-M form). Regardless of which bumper you use M or not, you will probably have to do some fender work. You might be better off getting a new 1/4 panel custom made.
Depending how far you are going to take it, you could do work to your rear fenders/panels too.
Whatever you do, think about how the whole car is going to look. Part of my job is doing 3D models of product concepts. I wish I had something as beautiful as a car to work with...but even on these more industrial things, I can be hard to get the lines right.
Good Luck. |
