I dont remember what the back spacing is but i can tell you that they were made for tahoes and trucks in mind. They stick out about 2"s.
No rubbing, and I have tried soo hard to make them rub and I cant. I will tell you at total collapse to the bumpstop they are very close though. =) Belive it or not that even though they stick out 2"s they will tuck very nice into the fenderwell in the rear. The front would hit but they hit the bumpstop so you can still turn your tires while under max flex and not hit the fenderwell like we would on the Jeeps.
