Hey does anyone have this harness bar? As much as I wish this was a pic of the back in my Supra, but it isnt. I found this pic (and the bar for sale), off of Titan Motorsports. I want to get it for mine because (I think) it still allows for the original 3 point belts.

The asking price is a lil... INSANE. But it's still worth it. I dont want anyone sitting in my backseat anyway.

I am not a fan of harness bars. They should be integrated into a proper roll cage along with the mounting points for the seats. The idea is to create an integrated cocoon inside the car. I suppose they are nice for show, but if you are racing and get in a wreck the seats can tear loose and you will be squished between the harness and the seats. Hence the full cage in my truck.

Actually, you're not safer without all the gear, and even with it not on the streets. All this equipment was designed around track collision scenarios, where head-ons with other vehicles and such are next to non existent.

A harness by itself has only downsides, and getting squished as TcmaBoy pointed out is the main reason. Not just from the seat though...in a rollover, the roof will collapse to a certain extent. Ever wondered why 3 point shoulder belts have the opening on the inside of the car? So your body has somewhere to go if that occurs. A harness will lock you in until the roof meets your brainstem.

A 4 point harness is the worst of all worlds, as it allows and actually promotes the "submarine". This is where your body has nowhere to go but down under the lap belt portion due to seating position and your internal organs rupture as you go...not pleasant!

So IMO, the use of a 5-6 point also requires a full cage, and a helmet (bouncing your skull off a cage tube will kill you pretty quick too, or worse leave you a pretty nasty brain injury), and those both require a HANS like device to keep your head attached properly. The only exception is perhaps off-roading, where the speeds are low and the only real worry is for rollovers, not high speed collisions, so you can probably omit the HANS device, but I'd keep the rest.

On a roadcar, they are in all a bad idea IMO...

I wish more folks wore helmets when playing in the rocks. If you flip the truck your head can meet rock in a hurry (and those cage bars do sting a bit).
