I recently helped my friend mod his M5 he lovingly calls Bruno. Put some 21" Interad DTMs on (my old wheels) Brembo 380mm BBK front in Rose gold with classic type RPI scoops in Rose Gold Mirrors in Rose Gold Full 2010 LCI Light conversion other mods include full rpi except headers, H&R Springs...

Here's some shots I took recently of this Alpina Definitely one of the most gorgeous cars I've seen The wheels would have been better off in 22's but 21's cut it Enjoy: http://www.enlightened-aesthetics.com/2011/08/snowflake.html
