I just installed the toytec ultimate front coils set at 1 3/4 of lift, and T-13 coils with bilstein shocks in the rear. Rear before measurement was 36 1/2", after the lift and driving a couple days 38". This is to bottom of fender. Should have done center of axle to fender but the math still the same. So I got exactly 1 1/2". This is a 2013 trail with 265/70 r17 tires, stock bumper, full of fuel, the normal recovery/survival gear, and tire chains in the back. Turned out perfect. I like them more firm but not bad. That could be the shocks though.
