Just wondering, has anyone tried installing an m3 bumper to a a e46 sedan? I've seen pix of them and want to know how to aproach this project.
I've heard that you have to apply body filler inside the corners of the bumper, and the when you put the bumper on, you sand the bumper down (because of the wideness of the bumper).
Can someone give me the DIY for this project? thanx
