Doubt anything 9" wide wide will fit with stock suspension, unless you run some larger spacers to keep the wheel/tire from rubbing on the strut. Then you're gonna need to roll fenders for sure. I had to run 5mm spacers and roll fenders just to fit 7.5" wide wheels, due to the meatier tires I have on them. Coils will help out since they eat up less wheel-well area. Camber will always be an issue on G20s, since there's not a simple camber adjustment screw option for our fronts like most vehicles have available to them.
