Bike looks sweet BigPoppa. If you want mirror extensions, get in touch with Thinker62 (Greg). He has a buddy who makes some nice polished ones. I put my set on the other day and they are awesome. The guy polishes the spacers to high luster that looks very very close to chrome. Now, I'm 6'5" and have broad shoulders and those spacers did the trick. Sure you can buy those black rubber ones, but they don't look nearly as good as the ones from Stevo. If you are planning to do any polishing or chroming, then these spacers will add that custom look. BTW, I just found Stevo's number. It's (503) 869-9499. He also makes some other nice stuff for the Busa. I'm looking into getting some of the billet aluminum hand grips next. Good Luck!
