Schroth Racing makes DOT street legal harnesses, they private label many of the harnesses for Sparco too.

I'm much safer with my Schroth/Sparco six point harness with my butt firmly planted in my Sparco DTM's - These seats have a carbon fiber honeycomb composite shell that has been proven to withstand stresses of over 2200 pounds!!! I'll have other things to worry about in a roll over other then the roof crushing me...

Before you go installing a harness bar or roll cage, replace your seat first! Buy something that was design to work with a four/six point harness...

I'm no expert, but I would like to see someone quick enough to crawl under their dash while in a roll over as the roof is crushing down on them sounds like the old 'scare' sales tactic - a harness bar isn't going to help you...

 

No one in the thread suggested a harness bar offered any sort of rollover protection or any crash protection at all - that is not what it is designed for. It is designed to give a harness someplace to mount to without resorting to a full cage.

It's easy to come up with a million scenarios where any of these items can be less than desirable, causing injury, or worse, to the occupants. The bottom line is no harness should be used on the street IMHO, nor should any roll cage. Those are safety devices designed for race cars, running on closed tracks with sanctioning bodies governing every aspect of each component.

 

Having an 'opinion' is one thing - telling people that they MUST purchase a harness bar in order to use harnesses is mis-information...

 

you obviously did not read what I wrote on page 1

you need AT LEAST a harness bar...meaning, that is the MINIMUM thing you need to install and run a harness

 

as posted on 7/23 in this thread

 

NO, you do not NEED a harness bar! What are you over stocked on these things?

As long as you maintain the correct degree angle with your straps mounting points, there's no disadvantage with installing some eye bolts and using snap-on or carabine brackets... That's just the point I'm trying to make...

Seat back strength is what people really should focus on before they use harnesses...

 

no, in fact I don't even have them in stock

there is no snap on bracket you can use in the hatch area that I've ever seen - those tend to be for the side areas on either side of the seat. Same with the eyelet hooks - you can't just screw those things into the floorpan of the car and be done with it...that is not safe

 

I'm just messing with you...

I have a G35 Coupe, a bit different setup, but still - some SAE grade 5 bolts, insure that you have individual mounting points for each harness that each mount to the frame (roll structure-seat base, etc...) is all that's NEEDED/Required... Obviously bolting to floor panels is just not going to cut it...

My point still remains, that there are options, and a harness bar is not required...

 

I know

You are comparing apples to oranges though

A G35 has back seats. As such, there are rear seat belts, and rear seat belt anchor spots predrilled/threaded into the car. So, you can install a harness just like you would in a sedan, like an Audi, or an STi or an Evo.

A Z obviously has no rear seats - there are no seatbelt anchor spots. Sure there are the areas where you could go to for the baby seat, but I believe that puts things on too drastic of an angle to make it legal, or even desirable.

I stand by what I said - to do harnesses on a 2 seater car, like a Z, you need, at least, a harness bar. A roll bar with integrated harness bar, or cage, is the preferred method of course for more serious competiton

 

First, I keep forgetting this is a 350Z site -

A harness bar would be easier in a Z, (not so in a G35 or any other four seater car) I'm in agreement with you there - but again, for the cost of a harness bar, you could still install bolts (weld in a plate bases, etc...) and have a cleaner look... It's up to the end user, but options DO exist.

 

We'll agree to disagree then - my point is this:

Could you weld in plates to the factory floor? sure - and then cut your carpet up so the eyelets peak through, and be left with a permenantly mounted plate and hook in the car.

Or, you can install a harness bar, which is a bolt in affair, and removable at any time you want

So do options exist? Sure, I guess they do - they just are not exactly practical, let alone reversible.

If it were my car, and harnesses were a "must have" for competition (ie a sanctioned event, not some fun time at the track type thing) at the very least I'd install a rollbar with integrated harness bar, ala Kirk, Autopower, et. al.. If I were doing non timed drivers days, a simple bolt in harnesses bar, of which there are many, would suffice, IMHO.
