A harness is day and night vs an OEM seat belt. I autocross routinely almost every weekend of the summer, and when not autocrossing I'm at a road course event. I have go-pro vids of my oem belt vs my harness mounted behind me as well as on my helmet itself(went 3 years with an OEM belt before finally doing a harness w/ belt). There's no way of getting around your knee bruises from the door/inner pillar besides knee pads, but watching your shoulders/head shift limitations from OEM to a harness isn't even funny. The amount of focus you can retain on the course is literally day and night. I knew within the first 30 seconds that my harness and bar was easily one of my top add-ons for the track. The harness bar is the added support you need to safely/correctly mount a hardness belt. Also, the hardness bar allows you to still retain your OEM belts, making it easy to hop in and out for that quick drive around town. Your OEM support bar in the rear is...just that, a support bar. Its not strong enough to hold a belt. Replacing the OEM bar(Robispec) is not optimal as the max you want the mount to be is 20% from the seat openings.

I know the point of a 4 point harness, I don't know the point of a harness bar. Also the way that thin steel bar is done is just like the subie/evo bar and in an acciden the two bolts lower to the belt snap, the bar rotates on the other two where the seat belts were and the occupant goes flying out the windshield. Has happened several times on and off the track on other cars.
Also I should note that 4 point harnesses are stupid and you will be F'd up if you crash, you need to have an anti submarine belt when using rigid mounted shoulder belts. Throwing this in for some info http://www.ogracing.com/blog/2013/02...ing-harnesses/

2. I personally run the Schroth Anti-Submarine 6 point 3. The bar has no way of rotating in the 370. This is not an Evo/Subie. The 370's roofline is too low, and the support bar and actual subframe would never allow the bar to rotate around as you're suggesting. 4. Thank you for all of your concerns, any other questions I can answer or arguments you would like to throw my way, happy to help Last edited by 1cleanZ; 11-10-2014 at 12:45 PM. |

yup so driver + passenger + weight of the seat back + the weight of the belts * 6 applied to the bar where the harnesses connect and watch what happens. NO ONE actually crash tests these things to know what it is going to do in an accident. The amuse bar is a F'n death trap, the robispec bar is probably the closest thing to strong enough but in an accident who knows.

This is a pretty good bar that uses the factory mounting points. I am thinking about using it for autox. For $200 bucks its worth a try.

-The bar looks like its right behind your head?resisting how far the seat goes back? -The harness anchors are off centered? -The structure of the mounting points look kind of half a$$ed, making up for lack of engineering and fitment -The bar itself is actually 3 connecting bars (multiple screw connection points = weaker supporting bar) Last edited by 1cleanZ; 11-10-2014 at 03:39 PM. |

Good point about the anchors being off centered, I didn't even notice that. The mounting points arent perfect but I think they are better than that of the robi bar. I say that because those points are designed to be load bearing points and should be safe in a crash. If the bar is safe is a whole other question.

Here are a few photos in the raw of the actual connection points. You'll see that they do not go into the "support bar" which is very thin which is not recommended to support harnesses, rather they go into the actual supporting joints to hold in the support bar which are much thicker. Also, they bar goes back far enough to fully be prevented from rotating downward in the event of an accident, so all of this talk about it rotating around in the event of an accident, is irrelevant.
