I just added the 2" blocks on my truck w/ ACE. Haven't upgraded anything else; still stock shocks, steering, ECT. The ride is great on and offroad and the attenuation is still better than most Jeeps. I do plan to add the extended break lines and 2+ shocks, but looking at the rear of the Disco II I need the break lines first. They are close to their max reach with stock shocks.
