Any time you use a drop coil inner tire wear will be increased. The more drop in the coil the worse it is. Even if the arms are set to proper camber at static drop height the camber curve is accelerated due to the arms sitting at the wrong angle. This is claimed to be corrected by some aftermarket drop members and can somewhat be compensated for by changing the suspension geometry. If you drive the truck a lot spindles are a no brainer. Adding a drop coil to them will increase tire wear. With a spindle and 3" drop on the coil in my 94 10-15 thousand miles is all I could expect on the front tires and it was aligned properly. Went through 3 sets of tires at that drop height. I enjoyed it and expected the tire changes.
