08 sport here too. Did you get the rear spring tsb? The front 5100 Bilsteins are adjustable, not the back. A year after i had my tsb done and it has settled so .85 looks best. Use your jack and see what looks level. I have the Tire size you are planning on-- 265/70/17 and they will fit with stock shocks. First thing I did was go up a size with tires and no problems.
