My wife and I have "his and Hers" Stallions. There is a difference of one inch in clearance from the floor of the garage to the tip of the front fender. One is at 19 1/2 inches and the other at 18 1/2 inches. The 18 1/2 inch clearance is causing some fender rub on the front tire in tight turns. Anyone know what the clearance is supposed to be.....and/or how to adjust the front wheel clearance?
