[CH.CRAFT]

I LOOKED IN MY IHRA RULEBOOK AND THE WAY I UNDERSTAND IT IS THAT A CONVERTABLE HAS TO HAVE A ROLL BAR AT 13.49 TO 10.00. AND AGAIN MY TRACK HAS A WAIVER FORM FOR, I THINK, 2008 AND NEWER FACTORY PERFORMANCE CARS. I THINK THE E.T. CUT OFF WILL VARY FROM DIFFERENT TRACKS BECAUSE I AM PRETTY SURE I HAVE SEEN CONVERTABLES RUN QUICKER THAN 13.50 WITH NO ROLL BAR.
