Post some pics when done and good luckdankbmw said:hey everyone...i am in the beginning stages of putting an m3 bumper on my 2000 323i, and i got a quick question. My 323 bumper has a steel reinforcement bar in it, while my m3 has a foam reinforcement bar...do i rip out the foam and replace it with the steel one from my 323? or do i just install the it with the foam? Do i drill those huge steel bolts into the foam? any help would be greatly appreciated. Also i am melting the sides of the bumper where it meets the fender...I will post pics as i go, also anyome who has done this let me know how it turned out!!!!
