Before bags I measured 30.25 on driver front fender and now its 26.5. Passenger was 31 and now 26.25. I didn't trim the cups at all. Seems I can trim them 1/2 an inch and I think that would be an inch of drop if I did it. The plan is to go with 3 inch drop spindles since I have the heavy duty rotors. Right now I can put 90 psi in to lift the front and enough air to lift an inch it rides pretty good. I tried 2 inches of air and it was stiffer so im thinking 1.5 inches of lift should be ideal.
