Andy, the original rims on mine are 17's so i adjustsed the size to be what looked like 1.5" bigger on each edge, they will be larger once I get them on as the tires on there are still the ones on the 17's. That and she gets lowered before I get them rims. I just haven't decided if it 1.2" or 1.8" drop.
