c'mon... its a no-brainer...
Alpha One splitters!
I too have the BSM, with CF performance parts (Mirror caps and spoiler), Black Kidneys; also black markers and black emblem w chrome surround (pending delivery form IND) would love to do Akra (with Ti tips though) this spring according to how funds go.
Since you have the CF diffuser in back, you need to balance off with CF bits upfront, making for a uniformed look IMO. Ride height sacrifice is miniscal, I had mine mounted since june last yr and have absoultely NO RASH (I do pay closer attention to potholes and angles); with stock suspension.
