I'm running the same wheels that you are, but in SS. Since we have to stick with OE widths and diameters, I don't feel the need to get different wheels, even if they're a little bit lighter. If I ran across a set that fit, were strong, were 5 pounds lighter per corner, and weren't ugly, I might reconsider. I have a set of the lightweight RAC group buy wheels on order, but won't use them for autocross, at least as long as I stay in stock.
