Re: 2005 GC opinions
I would keep stock height, renew all suspension bits. and get engine upgrades. Lowering, big wheels, etc gives better handling, but a MUCH rougher ride which creates squeeks and rattles, and can't go off road any longer in your Jeep. Lifting is if for those who often go off road, but doing so means it will ride and handle worse on road, and get worse mpg. plus the added cost for big wheels and tires.
Stock height with Koni FSD's IMO is the best of both worlds; handles superb in the twisties, and ride is not harsh, also good for off roading, and can stick with stock wheels and tire size, good for both on and off road.
