Default Backspacing and shock help.

I own a 1997 XJ Cherokee Country 4.0L 6cyl and it is currently stock. I bought a Rubicon Express 3.5 inch Super Ride with full leaf spring lift kit and I'm waiting to install it until I get wheels and tires. I've decided I wan't to run 32x11.5 inch tires on a 15x8 inch wheel. So my question is what is the best backspacing for 32x11.5 on a 15x8? The specs for the RE lift kit recommends a backspacing of 4-4.75 inches for a tire wider than 10.5 inches, but I don't want my tires to rub the control arms during a turn. I was thinking either a backspacing of either 3.75 or 4 inches so what backspacing would you recommend? If you all have any pictures of 3.75 BS or 4 inch BS please share. My next question is what shocks would you all recommend? I was also thinking about buy/installing front and rear bar pin eliminators so are they worth it?

I'm running 33x12.50 ,and my wheels are 15x8" with 3.75" backspacing. Nothing rubs on the control arms. No rubbing even at full lock, and the stops are still set to the factory position. Sorry, no pics at the moment.

4-4.5" will be fine for an 11.5 tire. Eventually you will go to 33's (a 32x11.5 really isnt much different in size, but is harder to find). Go for 4" backspacing. Allot of folks run bisltein 5100's. I ran Skyjacker hydro 7000's and found them to be a tad soft on the pavement, but great off road.
