Years back I learned a valuable lesson regarding tire / wheel size. It was with a Mustang Cobra, I jumped up from the stock 17's to wider 18's (265/35 front, 295/35 rears), dropped the car with an Eibach Pro-Kit, did some more suspension work for open tracking. End result was an incredible improvement in turn in, general handling and overal look / stance of the car. Now the downside...the car tracked horribly on public roads and became too much of a handfull for the wifey to enjoy driving. She did look good though.....
