With the addition of a proper racing seat on side mounted bracket (as in this case) often you sit about 2 inches lower than stock, which would allow a good portion of individuals to be under the factory roll hoops.

That said, I think the issue with this set-up is that is a very flimsy place to loop the harness. That mounting location will not hold up to the forces in a frontal collision.

 

creativity: A
execution: B+
broomstick test: F-

 

4000 lbs of total load but divided by the number of mounting location. each mounting location would take part of the force, not the full force.

 

It doesn't work like that. Beams and trusses aren't quite as simple as this implies.

It's entirely possible for one or more of the mounting points to take MORE than the total load. That's because reaction forces can oppose each other, and only the net total has to be equal to tha applied load.

 

i think this would be a good idea to use as alternative harness mounting location but a proper roll bar is still needed to clear the head. this would be good to use with the hard dog roll bar because the harness bar that it comes with is not in the ideal location and it will also allow access to the secret compartment, but only with an additional diagonal support bar like Rob mentioned.


this is how i mount my shoulder harness.

 

beams and trusses are rigid structures and seat belts are not.

i have no engineering back ground and i'm just speaking from common sense but i would think that a 5/6 point harness is designed to spread the force out so that no one mounting point take the full load on impact. because i don't think that any single mounting point can take a full 4000lbs of load (other than the one bolted to the proper roll bar). that 1.5 times the weight of the car. and we are talking about a frontal impact.

 

Interesting. That's the best-looking load path I've ever seen for any of the "mount my harnesses to the roll hoop beam" solutions.

 

Thanks for all the input.

I understand your point but did tae them into consideration.

With this seat , with helmet I am actually just lower that the roll hoop and the angle of the harness is better than some of the full roll bars that I have seen.

Th strength of the bar I assumed (yes assumed) would be strong enough as a point for the original seatbelt is on the same bar. I am confident in the welds (done by FIA certified welder), who agreed with me it would also be strong enough.

??????????????????????????????????????????????

 

there are a lot of people on this forum that will give advice they really dont know about.. there are a few on here that you should take their advice seriously.

I personally have taken over 10 s2000 interiors apart for soft top swaps and guts including my own. i also trust that honda engineering is top notch. they knew what they were doing from every angle of this car.

I also have turned an s2000 upside down.

the fact is that in an overturned s2000 (depending on the impact) the roll bars should never touch the ground themselves.. infact the windshield frame and the edge of the trunk should hold the car up. I know from personal experience.

Take a long broom stick and rest it on the top of the windshield and on the edge of the trunk over a roll bar. it shouldnt touch. u should have a few inches of space between the stick and the roll bar.

regardless... running a harness and no roll bar can be unsafe. running a harness and no suit could get messy. there are a lot of what ifs when it comes to safety and sports cars. drive safe. if ur on the track frequnetly then u need to upgrade..

 

This is very foolish advice.

I take it you haven't seen the violence of a high speed track incident.

I tracked my car for years in stock form, but I knew I was taking my chances. All this stuff is personal choice, but at least it should be informed personal choice rather than ignorance.
