Since the car will be running with alot more power after this winter I would like to be running much wider rims for track use, but was informed it is a good idea to keep the stagger. So I want to go with 18x10.5 rear and 18x9.5 front, so i need proper offsets for these sizes. Also what tires would you recommend for each. I was thinking 295/35-18 rear and 275/35-18 front. Any info would be great help. Thanks.
