It is not so much that it lets you slide or what not, its that if the car flips, when you head hits in a 3 point, you body will get pushed by the weight of the car and the free shoulder is able come forward enough to let your head be displaced enough to not smash you spine/neck. and this can still happen in a racing seat as long as it doesnt have those large head extensions or whatever they are called. Based on all the accidents I have seen the aftermath of first hand, you would be amazed how much a body moves around in the OEM 3 point, even when the seatbelt is locked. There are forces much stronger than what you can exert on your own. However, in a 5/6 point there is no movement at all except for the neck, and this is not enough to allow your head to be displaced enough.

long story short: there is a reason many sanctioning bodies do not allow Harness - roll bar in a convertible.
You're assuming the forces that hit your head comes from slightly behind the head. What if the forces comes slightly in front of the head and pushing it back against the seat. Or what if the forces hit you right straight on top your head to your spine? When you roll over it is so violent, and confusing, since t is disorienting, you can't do or think to do anything. The best place you can be is strapped tightly on your seat.

A lot of sanctioning body doesn't allow a lot of things because of many issue. Some is to prevent a lawsuit.
Actually I assume a side force based on what I have seen in the numerous rollovers (some with convertibles) in 6 years with a fire company as a firefighter and vehicle rescue specialist. Rollovers usually are to the side applying said force. But in the end, a 3 point does allow your body to move around a LOT more under the stresses of an accident than you realize, even in a racing seat, especially since the belt material tends to stretch under such forces. You can try to figure it out logically all you want, but I am going go go off of both real world observation, and in car crash footage shown during training. You cannot replicate the forces of an accident by trying to move around. Yes, there are some situations where you are screwed either way in a rollover, but there are also much more common situations where a 3-point is a lot safer in a rollover compared to a harness when not paired with a roll-bar.

I have the regular one, If you would like to test sit in mine, you can either swing down here or, I will be in Dothan, AL (a little closer) tomorrow for an Autox.
Do you have any pictures of these installed in your S?

Jim
unfortunately no, but there are a few pics floating around this site of that seat in an S. Just FYI, I only have it in the drivers position, I have OEM on the pass side.

I guess, we agree to disagree. I'm not rationalizing. I'm an engineer by trade, and racer as second job. I've been in a few rollover my self, not something I usually brag about.

sounds good to me, its good to have info supporting both arguments available, both by people who at least are drawing on experience/education.

The evo2+ will not work on a street car, though.

I'm looking at the Evo 2 Plus and the Kirkey Intermediate, so you're a good source :-) I have a lower harness bar on my hard dog and am planning to use HANS. Why do you say that the Evo 2 Plus will not work on a street car.

Yeah, seat buying sucks. I purchased two seats myself without sitting in them. The first was too small, recaro SPG profi, the second was just right, sparco pro 2000. Both had required different hardware to fit properly.
2 questions, how is the fitment in the car of the Sparco? and what hardware did you need to fit the Sparco v. the Recaro
The recaro used taitec rails, the sparco could not go low enough with the taitec base so I purchased the buddy club base, and used the taitec mounting hardware. Then I cut (sparco) the left shoulder wing to fit inside the door. I also used some rubber to push the seat belt receiver out so I could reach it from above and between the tunnel and the seat. The sparco was much more work to fit, but it fit me better than the recaro.

What did your sparco end up looking like after you had to chop the one side some to fit the car?

Was the Pole position not right fit for you? Just seems like alot of work to make that fit, and cut up a new seat too.

Mugen s1R here.

Seats fit like they were made for the s2000. Waist lines over 34" need not apply. Seat is extremely light.

*Not planning for the future and purchasing the harddog bar with higher harness bar ftl.*

I keep hearing that the hard dog roll bars have harness bars too high. I also hear though that it's the only SCCA/NASA approved roll bar for the S2000.

How are we supposed to get a roll bar and harness that actually all work together then?

Whenever you buy a HD roll bar you can request for the harness bar to be welded at a lower position, so that's not an issue. But when doing that I believe you have to take out the factory hoops. I think you mean that it's the only SCCA/NASA approved "bolt on" bar for the S?

out of curiosity, what is the issue that is caused by the bar being too high? (not doubting that there is an issue, just curious as to exactly what it is)
