My ltwts are the genuine porsche 5 spokes for the boxster....I bought them used from Earnies in Florida off ebay....paid $1500 for them. They were in almost perfect shape, only a couple of small scratches on 2 of the rims.
So if you are diligent, and troll ebay like a fiend (like I am addicted to doing
) you can get some good deals on wheels.
Try a place called wheel enhancement as well, there are in culver city and have TONS of used genuine porsche wheels, and lots of brand new ones too that were take offs on new cars.
