So what is available? Well, everything for certain Motorsports cars. Here are the catalogs for the following vehicles:
2008 Z4 - http://resource.bmwusa.com/Pdf_07298...149c245b4.arox
E36 M3 Group A - http://resource.bmwusa.com/Pdf_f29e3...c9a35ee52.arox
E46 M3 - http://resource.bmwusa.com/Pdf_99a8b...4f6941759.arox
E90 320si S2000 - http://resource.bmwusa.com/Pdf_ccdba...e44e34f8e.arox
E92 M3 GT4 - http://cache.bmwusa.com/Pdf_2f462d7a...e8d942b49.arox
Definitely some nice suspension and engine options available. Plus lots of other motorsport tested parts. This is a giant step in the right direction and obviously not the entire Motorsport parts division, but BMW says more is on the way
So, if someone really wants the P54B32 race motor (based on the S54), they can now have it:
How about just the cylinder heads? Sure, no problem.
So... that widebody M3 and Z4 Motorsport Body Kit? We may have those available soon as BMW says this is the beginning of an expanding list.
Today... is a great day for BMW performance enthusiasts in the USA, thank you BMW, about freaking time.
