Re: index changes
The roll bar requirement for M/SA was because the record was in the 11.'s and at that time the rule book required a bar at 11.99. However, that should still hold true for the A cars as well since the record is well into the nines but it doesn't. Just like needing a certified cage for GT/GA and not for H the G record is or at one time was in the 9's.
