370Z Harness Bar

The 8G estimate seems very low. F-16 fighter planes pull a constant 12Gs and the pilots have no vascular injuries...they just pass out if not wearing G-suits. In a sudden, frontal collision, depending on your speed, I'd expect something between 30-60Gs for a 30mph head-on collision. This however would be incredibly transient which is why people can survive these accidents.

Also, as one increases the number of mounting points to the car, the required load-bearing capacity of each mounting point, for the same maximal collision load, becomes less as well.

My concern with these modifications is that people will replace their well-engineered seat belts from Nissan with aftermarket, 'these look like they can bolt-on here' harness bars and then be in big big trouble when a serious accident occurs. You may be fine for the small accidents, but the big time crash may turn a poorly thought out harness bar into a bent coat hanger with you landing 3 turns further up the track.
