Just my two cents but I'd avoid power mods (obviously, not me personally!!). Keep the powertrain stock, under warranty and serviceable. Go for a signature suspension, wheels & tires and proprietary graphics. That would be my Stage 1. Buyers would arguably be starting with a Rubicon which they may already see as an upgrade to axles, transfer case and so on. My Stage 1 would be a small bump in height, big bump up in twist on 35's and a "look." If you want to go further, my Stage 2 would be a touch more height on say 37's, with flares and bumpers.
