Personally, BBS look right at home - but if you're gonna go with the 'Pina's go back to silver (as others have said) or if it was me, paint them black and have the rim diamond cut & laquered (I think that is what Ric325i was hinting at too!)....it'll look better than the grey and give more of a contrast.....
Bruce.
P.S. If it was my motor, I reckon the red would really work with a set of
THESE - Chop in the Alpina's and the BBS's in and you'll more than cover the cost of the A's
and some nice rubber! (THEN paint the centres black!

) You know it makes sense......
