If the car rolls, the hoop is kept from flattening by that bar, think of the rafters holding your roof up. They keep the walls up straight.

Removable just adds in places for pins to sheer etc.

You'd also run into the whole head smashing the rest of the main hoop deal. Hell, the rear bars over the top of your head wouldn't feel too great either.

As long as you realize it is just a feeling.

Eh, would rather be higher than someones bumper and have a nice working airbag system with ABS etc.

Just wear a helmet whenever you drive on the street

This is a good idea.

Don't get me wrong, I understand structurally why that bar is there. Just seems to me that something could be engineered to make a joint that would be as strong as a welded joint but removable, even if it had to be bolted in to install instead of popping a pin in.

You still have plenty of exposure to the main hoop and the downward rear bars. There is no way I would ride in the back on the street. Hit a big enough bump and you'll have a goose egg for a hat.

Yup, the back seat is off limits even with a 4pt

It actually wasnt bad at all in my GN with a 6 pt bar... once you were in the back it was pretty comfy. :kneeslap:

it's not about comfort. it is completely unsafe.

Which is why I'm keeping my build mild. A big part of the enjoyment of my car is taking the family for drives in it and last I checked you can't fit a third person (my daughter) without the rear seats.

If I had a family, I'd do just that.

Never mind back seats, Kohler rarely has the front seat in the car. Lettuce be cereal, this is a racecar that is driven on the street. It will need a 10pt or at least a 6pt to sneak by. If you build a car to run 9s you should be ready to give up some safety and comfort on the street.

Install the main hoop far enough back to recline some or get seats with a high back for your dome piece. Either do removable swing outs or copy what I did with the door panels for more room. Wrap the bar in padding around the hoop and sides. Dont be a dumb ass when you do play on the street.

:themayor:One thread talking about no bar and one thread talking about 150mph traps.

Do I race officially? No. (IE I am not looking for 100% adherance to NHRA rules being as its a street car before race car)

Is this a race tech area to hash out what safety stuff I need? Yes.

Not sure why I can't plan for MPH and talk about the required safety stuff at the same time.

(And no way in hell that pile is going 150mph)

To bump this back up, prior to hans devices catching on, a harness and helmet was all that you wore. Now, this seems like a great way to snap your neck no?

Harness holds you tight, added weight to head and hello whiplash.

PT thoughts on this Bonzo?

Neck collar thing? I have a foam one from old man Bill.

From what I have read, they are a useless piece of equipment meant to satisfy insurance underwriters.

Yeah. Pre Hans is a neck roll

Technically i think the head rest on the seat stops whiplash - the snap back. look at 60s muscle cars with those low back seats. I'll never have a car with those. I think what you are concerned about it breaking your neck and maybe basal (sp?) skull fracture - ala Dale Earnhardt. I'm not a doctor but i stayed at a holiday inn last month.

All the guys I know who road race seriously run a HANS. If i were at a point where i was wearing a firesuit and running a cage I'd probably consider a HANS a lot

Yea, the seat rest will stop you from snapping back but lets say you smack a wall or sudden stop due to whatever, your neck/head/helmet are snapping forward and body is held tight (within some amount) by the harness.

Obviously not all sanctioning bodies say hans is required so just curious on this.

Again, theory talk here.

Is it a good idea, sure it is. Do most do it, no. How much do the Hans devices go for these days?

Depending on which head and neck restraint you get you are looking at anywhere from $350ish to thousands depending on brand, material, and design. Beyond price you also have to consider how you plan use the device.

Fixed units like the HANS brand restraints are intended for specific ranges of seating position and driver size. Some of the hybrid and Hutchins style devices can be adjusted for various lay backs and neck/upright angles. The only deivce that I believe was designed to be adjusted from the outset is the necksgen sold by Impact.

I take it you didn't leave your original belts in? Just checking.
