I also like the Khan wheels. For me, I see the BBS style everywhere, and they all blend in to me. The Khan is more my style...but again, just my 2 cents!
I'm diggin the BBS's. I've seen those in person and they have a really high polish/chrome esq look to them. Not to forget that they are lighter than the KHAN's. I've seen the BBS on a few different cars too, but not on an MP3.
REALLY like the Kahn ones. I'd get those myself! You can see the calipers better with these (which is especially nice if they're painted.) Plus, those will have a very nice spin on them, too. Go with the KAHN'S!!!!
