1. spindles are expensive. (not that expensive, but they will be once you finally get them cause u have to deal with aim)
2. They push the wheel out a little, which gives many people clearence problems. (espeically if its bagged)
3. I've seen a 15" wheel fit, its just depends on the offset. Its just not worth the headache to spend money to have issues to have fitment issue.
I have a set on the shelf for when I find a crew cab, then it will be to clear the 20-22" wheels. Heck, ihave just about everything exept the cab right now to make it, someday i'll smuggle one back from mexico.
