Backspacing for sport trac with superlift

[Bannanatruck02]

Hey guys and girls. After a lot of saving up, I am looking to do a Superlift for my Sport Trac within the next month. Currently, the vehicle has fx4 ii Alcoas that I powder coated and 31" BFG's, but I will need to replace them with a more aggressively backspace wheel to compensate for the lift and 33's I plan on putting on it. Any suggestion for a good backspacing that will be safe ( I want it to be as wide as possible) and I don't want it to rub... Any suggestions? Also, for wheels, I love the look of my alcoas- I just wished that they were available in 15x8. Also, after I finish the lift, I will be selling the wheels and tires.

3.75" backspace on a 15x8" wheel is typically the best option.
You don't want to go too wide because that will put too much strain on your front wheel bearings causing them to fail quicker.
