Re gear your axels. People only talk about this when it comes to large tires but combined with this 8 speed i think it would make the jeeps accelerate a lot faster. My sport s with its stock 31" tires has a first gear that red lines somewhere around 35 mph. Its geared tall enough to not spin the tires when full throttle off the line in 2wd. Lower the gears enough so that first gear only goes to 25 mph and this thing would be a lot faster. Your fuel economy would start to suffer above 40-45 ish mph, and would really be noticeable at highway speeds however.
