I am 5'8"ish, and not many passengers I will carry will be taller than me by much... my grandfather is like 5'10-5'11ish so thats all should be fine, passenger/driver height speaking...
Umm.. So for stock seats, I can run a 4pt harness to the childseat mount?
or is it not possible?

 

Nope, it's not possible for that mount to support the weight of a full grown adult. It probably would fail even if a large adult experienced heavy breaking while wearing shoulder harnesses mounted to that fixture.

 

Anyone did DIY harness bar?

 

Uh, NO! While those threaded holes provide enough strength for prevent a harness bar from rotating, they should NOT be used to mount a harness. Please forget about using a 4 point harness. they don't prevent submarineing(SP). Get a 5 point for race seats, or a 6 point with OEM seats. Also, mounting a shoulder strap there without a harness bar will cause spinal compression. NOT a good thing!

Do it right and get a BCR harness bar!

 

Where to get the BCR harness bar?
Where to get affordable 6 points?

The ONLY approved harness bar.

Yes, it's my company.

 

...
kind of steep... the bar($500) and the harness ($280 per set = pair i expect) would cost more than the seats im about to get (corbeau FX1PRO $279 retail!)

 

Harness bars are worth their weight in gold.

They must be responsible for .5-1 second improvement alone and certainly offer better consistency between runs. Being strapped down allows you to loosen your grip on the steering wheel offering better communication through your hands and behind (which is pressed into the seat and not moving around).

As for submarining, get a Schroth 4 point belt which has the anti-submarining feature. In a major hit, one of the shoulder belts actually expand allowing your body to slightly rotate forward over the hips so you effectively fold over the lap belt and not under it. It's DOT and TUV approved for street use as well.

 

I think your post needs a healthy dose of IMHO. Plenty of national championships have been won without harnesses, which would be nearly impossible were there really that big a time difference. I tried back-to-back runs in my car with and without the harness and couldn't identify any discernable time improvement.

I absolutely agree that a harness helps feel, but to assign any time improvement to one, let alone a full second's worth, is pretty iffy in my opinion.

 

I have a 4 pt system in my car and I found that it could have possibly attributed to some improvement in my times. Maybe more on the order of a 0.1 or 0.2. However whenever I drive a car w/o a harness system I found that I am now worse since I have become dependant on the support that the harness system gives me.

 

Get a CG lock they are like 30 dollars and do the exact same thing as a harnes OR you can do it for free. Put your seat belt on. Push your seat all the way back. Make the belt lock and push your seat forward. Now you just saved a bunch of money. IMHO money saved on harnesses can gor to some koni DA and then you will see a seconds improvement.

 

I don't think so! The CG lock ONLY secures the lap belt. It does NOTHING to hold one's shoulders in the seat. Which is why I designed a harness bar.

 

Read my entire post on how to secure the shoulder belt for free. The BCR also might be in a gray area as far as being legal for anyone that drive BS solo2. Is it telescoping or ridgid? If it is rdgid it is questionable.

 

After looking at the pictures I'm fairly certain the bar is ridgid. I wouldn't protest it but someone might. The rule says the bar can serve no other purpose other than mounting restraints. Having a ridgid bar "may" increase the ridgidity of the car.

 

I can read, so I did read your entire post. Even if you can secure the OEM SINGLE shoulder strap, your right shoulder is still free to move.

I have no clue as to what you are referring to as to being telescoping or rigid? The harness bar is extremely rigid. It is a means of properly mounting competition shoulder harnesses.

 

Then it is illegal for b stock auto-x.

 

Well, OK, I think I understand what you are referring to. The BCR harness bar WILL improve rigidity between the "B" pillars (NOT a bad thing, IMO), but if the bar wasn't solidly mounted, it would defeat it's purpose!

It's kind of like a properly designed roll cage. Yes, attaching bars near suspension pick-up points improves chassis rigidity, it also adds strength to the chassis for improved crash protection for the driver.

 

I understand the benefits just stating that it is not legal for b stock unless it is telescoping. Usually the way telescoping bars are done is to make the harness bar in 2 pieces with one bar sliding into the other. It just as secure for the harness as there is no more forward backward movement than with a ridgid bar. Each seperate bar is nearly the same length as the other minus maybe an inch on each side so the car does not gain any ridgidity between the pillars. More to the point if it's not legal for auto-x where do you use it? You're risking killing yourself by wearing a harness without a cage on the track.

 

Sorry, I have no clue as to it's legality in auto-x.

The motivation for it's design was for HPDE's. I like sliding in 5th gear a LOT more than in 2nd gear!

 

Would you please share the rule about the "sliding" bar? I have never heard of such a rule. But, I'll admit I have a lot to learn!
