* Sport Car Club of America specifications for Solo I track events. Solo II requirements are much less strict often not even requiring any roll bar at all. ** You may see a large number of different double hoop bars on Miatas. Unless they have a brace running from the top on the hoop towards the rear of the Miata and are mounted to the body, they are just style bars that offer no protection in a roll over and are not covered here.
