Well this is my car stock springs KYB GR2's, stock body with a 15x8 4.5 inch backspace 275-60r15 MT ET Street. Just picked them up today.
Im changing out the wheels for 5.5 inch backspace as the fender lip is almost on the flat of the tread. No amount of rolling will help the contact other then lifting the car. I will take direct comparison pictures.
This is the Whole Car.
There is about an inch of gap around the whole tire. They rub on moderate bumps, and really bad on big dips/bumps. A 5.5 Inch backspace would make them clear with rolling of the fenders.
There is A TON of room on the inside of the tire to strut and fender well.
