How often are you going to be at full droop? Not very so you should't have any probs with wear, but if you don't like it run a small spaer made of plate steel bolted into the spring pack as thick as it needs to be to eliminate it 1/4 or 3/8" should cover it, that's what I did but I used a relocating plate to get my axle an extra inch forward at the same time.
