Im thinking Enkei CDR9's ... i like how the spokes come to the very end of the rims, giving the wheel a larger look. Maybe gunmetal.

it really depends how much i get when i sell my current rims, which are 17" gunmetal Exel Shu's wrapped with Yokohama tires..

 

I rub with 17's... I was looking into the 18's but you'd have to make sure you have all the fender clearance in the world!
