I got a set of BSA wheels for the track and I want to put some 305 TOYO RA1s on the back but I am wondering if they'll rub.

Do they in fact have 45mm offset in the back? What is the factory stock 18s offset?

LVDell

wide body? if yes, then you have the right offset. If narrow then you will be sticking WAY out.

Ditto from LVDell's comments. Stock narrow body 18x10's have a 65mm offset. I have seen C4S wheels on a narrow body and they do stick out. Since these are an inch more narrow, it won't be as bad. They will also rub if the car is lowered. You will have problems with a 305/35 on this wheel. It is too tall (1.3" taller than the normal tires for these cars). In addition, I would not recommend running that tire on less than an 11" rim. Those tires are about 2.5" wider than the wheel you are using. This is no problem in a straight line, but tremendous amounts of sidewall flex in corners. Don't be surprised if they rub badly on both the inside and outside if you choose to get these.

Tire size is right... wheel is pushing it. We do run 40mm on the Volk Racing Track wheel in the rear which does fit on the cup race cars. So you will be close.

LVDell

Correct that the wheel size is pushing it and should be an 11", but no way will it be "close" Dan. It WILL be sticking out way past the fender. I don't think he is running the camber and suspension setup that the cup cars are.

The GT 2 has 305 on 12 inch wheels, turbos have 295 on 11 inch. But I have seen 305 on 11 inch and they look OK.

Actually the GT2 has 315/30-18's on 18x12" wheels. These tires are shorter and wider than what Bowman is looking at using. This is also on a wide body car (GT2, Turbo and C4S) that has the bodywork to fit these.
