Installed a Set of StilAuto 17" Racing Wheels with 235/45ZR17 Dunlop 8K's. Ride comfort has changed noticeably from my 16" with Pirelli 6K 225/55/16's . The Handling has improved beyond words (traction). The car is on rails. Glue! I was thinking about 245/45's but I was really afraid of interference with the 35mm offset. So far so good.!
