Although I don't have them yet, I am looking quite seriously at the Firestone air-bags. When I hook my unit up it moves my headlights up so much that 'I qualify for a spotter of low flying aircraft'
; I need to bring them back down so as not to blind on-coming drivers. So, adding air-bags will not only help your own ride but make it safer for others on the road (at least in my opinion).
