I recently purchased a pair of Shine Js rep front fenders and Forcewerkz CG rep rear flares. The fronts are 35mm wider and the rears are 75mm wider. Using the wheel fitment calculator, I compared my current wheel set up to the stock ap1 wheels and my front are "supposedly" poking out 50.4mm and 55.4mm rear. With the 35mm front fenders and 75mm rears, that means the fronts will be sticking out +15.4mm and the rears will be sunken in by -19.6mm. Does this sound right? Can I add a 20mm spacer in the rear to make it sit flush?
