I did not check the rule book. However, I do not think you can notch the frame. That being said, it is not needed. I run an O/SA Malibu wagon. You can run a 3.5 backspacing, 8in wheel or I personally run a 4in backspacing, 8in wheel and a 1/4in spacer. Either of these with 30x9 tires should clear if the rear end is the stock length.
