Some body help me out. I plan on doing some work to my m and was wondering what to do about buying an aftermarket product versus euro model (sport evo III) products. parts to be considered are-
the headers- Bekkers Import carries sport evo III header for the e30 m3 US. would this be better than an aftermarket company like remus? does bmp make good headers. price doesn't really matter but i want quality.
chips- i could order the evo III chip from bmw germany, but would it be better to get an aftermarket chip from dinan or racing dynamics? what would give me the better performance, and more importantly, what would be better in terms of quality. my last bmw was entirely aftermarket in way of mods (no evo III stuff) and it was sufficient. just looking for answers i guess.
