What is required in a cage to go 9.90 I was at the fab shop and he was installing a cage and off the main hoop he had put bars down at a 45 degree angle that went into the aera around the mounting point for the lower control arm. It looks like if that was done on a regal those bars would have to be at a angle and would go through the rear seat. Are these bars needed to be a true 8 point cage.
