This is the only Vette I've ever seen with this type rims. They are basically the Mustang rim milled to fit Camaro, Trans Am, etc. They are 17 X 9 vs. the stock 17 X 9.5 so they make the stock 275 tire look nice and meaty. I also upsized the rear to 285 for a little extra uumph. The offset is countered so they actually appear about a 1/2" wider than the stock rims. Believe it or not, I bought these on Ebay for less than $800 for the full set new! The anthratic grey centers bring the colors on the car together nicely while the 5 spoke design sets the "vintage hot rod" tone that I wanted for the car.
