I had the same problem as GillesR - Moved front shocks to outer position no problem. Moved rear to outer position, and the back wheels no longer sit flat, the bottom of tires is pinched in and top of tires are sticking out. I have a 2020 Tracker 500s, same as the Kymco 450i, and arctic cat prowler 500. I do not believe there is any sway bar installed, shocks do not seem to be binding on anything - Any ideas??
