The front fenders are to accommodate 9"x15" factory Fuchs rims with 225/50/15 Yokohama AVS Intermediate tires at the front.
In the photo on the left, the fenders are mounted and the bumper is tacked in place with tape to mark the location for the front dam mounted oil cooler.

The photo on the right, shows the rear flares attached without the supporting pins. They are ready for final blending in.
