If your dropping down to 10" rims then I would definitely go with the 22/23 set up so u dont loose any stock ground clearance especially since your riding in rocky areas. Why sacrifice any clearance and your skid plates if you dont have too??
If I rode in around rocks no way would I go down to 10" wheels if u banged ur rim on the inside might smash into ur spindle I read it online some guys complaining about it. Just a thought. Take it or leave it
