I talked to Tire Rack, and there are some M3-type ATP knock offs (Type 5), in 17"-7.5" (could run 235/45s all over) for only like $179/rim! The ATP SPA 2 style is 17-8.5, 10" in the rear (for 255/40, the guy said it would work even if the car is lowered). The M3 rims seem like a pretty good deal, any good? Thanks.
Here's a link, who knows if it works!
