Looking at custom offsets online a lot of trucks with same size wheels with same offset etc and same size tires have different stances. Some still stick out further than others. Then I read where some lift kits force the front tires out more than others. The Superlift I'm getting says it maintains the original stance. Doesn't widen the front track. Also have seen where some have had to add spacers to the rears because of this. I was told by the shop that the 20x10 -18 wheels I'm getting should keep the edge of the tire within an inch of the flare which is exactly what I want. Will know soon enough. Can't wait to add pics to the "show us your lifted 4th gen" thread.
