Beemer = motorcycle, Bimmer = car. First lesson we all learn.
1. I stay away from replicas in general, some have had good experiences though. Buy them locally, plenty of shops around here have them.
2. Eurostyle (a member on the board) makes eyebrows, not sure if he has them for your car yet though. The little M3 lip you might as well get it on E-Bay, it's just a little tab anyways.
3. MarkD, another board member is doing software ("chip") upgrades, PM him to see if he can do yours.
Also come out to one of our weekly meets, every Friday night. Check out the Official Meets section for details.
