I watched the races and enjoyed them very much...Hight was moving at a fast pace when he hit the sand for sure...I would have thought the fire system would have handled the job but really you could not tell it did anything at all to retard the flames...I have to wonder if he failed to activate it of it failed on its own..When he hit the right wall he nailed it really hard so may have confused him some..and yes A. Force had terrible rt....If they change the chasis rule then they can use any little excuse to enter a totally different car, so I think leave it as is....
