I'm planning on going with the widest tires I can fit under the stock wheelwells of the car, but I also don't mind beating them around with a sledgehammer. It seems some people have tried 18x9.5" wheels with a 6" backspacing (5.5" for some) up front with little to no rubbing. These are the wheels I want: https://www.performanceplustire.com...romium-black-rim-with-machined-lip/ws:18x9-5/ I'd love to have the money for some actual CCW's, but I don't. While they have the exact sizes I need, they don't have the right bolt-patterns, and they don't do anything custom. The rears (18x11) won't be a problem, as if I get a 1" adapter, they should fit perfectly. The fronts, however, are the issue. There are two backspacing options I can get. I could go with the 6" option, which would be perfect size-wise, but the bolt-pattern is incorrect. I know some people get away with the 5x4.5" wheel on a 5x4.75" hub, but I autocross this car and drive it hard, so I don't really want to risk trying that (unless, with good ARP studs, you guys think it would be okay?). The second and more viable option is to get the wheel with 6.625" backspacing and get an adapter. Question is, do you guys think the 18x9.5 wheel would fit with a backspacing of 5.625"? Do they make adapters less than 1" thick? I would gladly experiment, but I don't want to have to keep paying shipping and restocking fees, and most adapters are custom and, therefore, cannot be returned. Thank you!
