To answer the OPs question, the ALMS M3 wheels you are asking about are BBS RE wheels. The ones you are looking at are the forged magnesium centerlock version.
They make a five bolt magnesium fitment for the M3, but are virtually impossible to acquire. If you want a set, they can be ordered through TCKline Racing. They are about $6000 per set of 4. I've only seen a silver finish on them, however. I believe five sets have to be pre-ordered before BBS will sell to anyone.
They are NOT street wheels. They are very fragile and will crack if subjected to impacts typically seen on the street.
BBS make an aluminum RE as well, but I'm not sure it can be had in an M3 fitment.
