love threads like these. You've got good taste and the "Bee" theme is pretty good too. Black wheels in my opinion look best on cars like red or yellow (silver may be). Never liked the blacked out theme. I think it's very good you matched the shadow line and grilles with rims, and followed up with Piano black trim. It looks just "right". May be not for everyone (yellow cars aren't) but I think it's so well put together that you really can't go wrong. If you get that M3 kevlar bumper that was mentioned it would really look great (the one that was on the blue akropovic M3 featured here earlier that basically looks like the more agressive OEM version - but not like that Amuze Ericsson thing which is horrible imho).
