Michael,

When you mention that you were told that "officials" were not going to allow the single anchor point "Y" shoulder strap system anymore. What officials are you referring to? If it is for a race group or track day, I would be surprised that they would allow anybody to be in the passenger seat without a roll bar on that side.

as twobjshelbys says, it is a trade off. What do you expect to be more likely, a rollover or a front/rear collision? Without a roll bar and shoulder harnesses in a rollover situation the passenger is not able to duck down and their head and neck areas risk of injury. Without the shoulder harnesses in a front or rear collision the passenger will experience whiplash and may strike their head on the dash or the rear deck. While the suggestion concerning the passenger being able to duck low during a rollover without the shoulder harness seems reasonable at face value, in a rollover situation the G forces would be throwing the passenger all over the place and it is questionable that a lap belt alone would maintain the passenger in their seat as the G forces would either pull them out of the lap belt through the top or they would submarine underneath the lap belt.

A lot to think about.
