Super nice wheels. If they were 15" or 16" I'd be all over it. 17 look nice, but on a stock 500 kills bottom end, even with a low profile tire. Good for highway though. Our little cars can barely handle the 16" sport wheels in my opinion. A 15" light wheel is what I prefer. Will, can you get a hold of some 15"?
I poked around a little. The rubbing in the back appears to have been caused by a clip weight. I removed it (it was a very small weight) and drove it about 3 miles and heard nothing. The clearance in the rear is TIGHT. that's what she said.
Car looks great, I prefer a little stretch myself but was curious on your clearance issues. Looks like the back wheels could be pushed out a little more as you seem to have space in the fender, and that is usually where my clearance issues arise
