I saw a set of gen 1 RX8s just recently, I think on Ebay for $600!!!
These look great and really suit the car, but for me I'm thinking OEM Evo X 18x8.5 Enkeis, 350Z 18x8.5 Touring or aftermarket.
You guys should see how well the Evo rims look on a MPS and same with the 350Zs which look some what similar to the RX8s but ain't flat and have some concave going on...
