Ditto on each of the previous posts. The only reason I have spacers on mine is that I like the Baja wheels. If your going to buy new wheels, get a proper offset. If you keep the wheels and use spacers, ensure you buy concentric spacers with the 108 mm lip. Lastly, T6061 spacers only, retorque at 100 and 500 miles, then retorque every 10000 at tire rotation. Cut these mileage’s in half if you dune or wheel frequently. I also replace them with each set of tires, but that is a me thing. Lastly, NEVER buy used and never sell them when you are done with them. While this seems extreme, aluminum will stress fracture like steel, but at less pressure, so with hard use they will fail...eventually. Just like wheels...
