I built my car to go racing and it has a single hoop homologated roll bar, with forward brace down to the main chassis on the passengers side, the bar is mounted on a strong part of the chassis!

The roll bar is made out of very strong material as per the regulations here in New Zealand, and I would argue that a full hoop bar is safer than a single hoop, I dont intend and wouldn't take a passenger out on the ciruit with a single hoop bar, so from the point of view of driver tuition for the newcomer - great I am all for safety!

My point is if you are not going to take a passenger then why do you have to change for racing - "You dont race with a passenger" what a load of cr*p.
