Thinking about gettin new rims for my car.Going to keep 16's on there(sorry no 17'or20's)Just bought new 16in tires so don't have the extra cash for tires to.Any way whats the backspacing for 16-8 or 16-10's?Thinkg of going wider in the back so what would be proper spacing for 10in wide rims in the back?Keeping 16-8 in the front,but may keep 16-8 in te back also.So any help would be great.Whats stock backspacing anyway?
