My dream street set would be a set of SSR RP-1s, 17x8 front and 17x10 rear. I'd get them in silver if Subaru gives us a grey BRZ, otherwise I'll go for gunmetal on a black BRZ.
For track wheels, hands down has to be BBS RS-GTs. I have a set on my Supra right now, amazingly good looking rims. Its a shame I won't be able to keep my current ones thanks to the odd 5x100 bolt pattern the AS1 uses.
