Hey guys, I'm very new to track days and I want some new racing seats, harnesses and a harness bar but could really use some help from you veteran track guys.

I have a 2002 Protege5 with Recaro Evo8 seats mounted in the car currently. They are certainly an upgrade from the Protege seats but I want to add harnesses to feel better planted in the seat and connected to the car. But I want to do this safely and legally without spending a metric butt-load of money. I plan on tracking the car in 2012 locally through NASA's HPDE and don't plan on racing or TT within the next 7-8 years, so just local track days and HPDE at Mid-Ohio, BeaveRun and Nelsons Ledges (near Ohio, basically)

Here's my problem; my Recaro's are great and I would love to use them but I've been told that NASA isn't allowing 4-point harnesses anymore (new to 2011) so I would need to run a 5 or 6 point harness, which the Recaro's do not have the center belt cut-out necessary. However, I'm not even 100% positive NASA banned all 4-points or just for TT classes or for all HPDE 1-4.

Next; harness bars/roll bars. I have been told bolting the rear harnesses to the rear seat bolts is a bad idea and possibly illegal as well. So I would need a harness bar, like the one made by Sparco. But I've been told harness bars are also illegal in NASA. So I would need basically a rear roll bar. But the mounting locations aren't really that different for the harnesses from the "harness bar" to the "rear roll bar"? Granted, the rear roll bar is better mounted so maybe that's why harness bars are illegal. Then again, Modified Magazine just had a short article about the AMS harness bar they installed in their EvoX that is legal for SCCA. So I would assume legal for NASA too?

Next up, harnesses; I like this Schroth 5-point harness but apparently they will need to be replaced every 2 or 5 years depending on the safety label on them? But the factory 3-point belt is perfectly acceptable even though it's 10 years old? And a friend pointed me to Crow harnesses which can be returned and they can re-web the harnesses and re-use your hardware.

I'm not a rich fellow, but want to keep myself and especially my instructor safe while on track. I've had two 20min Hyperdrives at Mid-Ohio and I am officially hooked on tracking my P5. I just have a lot to learn and I'm sure there are other members who have similar questions regarding seats, harnesses and roll bars as well. So a huge THANK YOU in advance for any help.
 
I went through this whole process a couple years ago when I got seats and belts for my Miata so hopefully I can save you a bunch of time. I was really paranoid about doing it right so I did a ton of research and asked a lot of people.

This is by far the best document regarding harnesses: http://www.schroth.com/installation-instructions/en/index.html It has great information about how to properly route the belts and the forces that act on the body during a collision.

It sounds like you already know this but your Evo 8 Recaro's don't have the pass-through for 5 or 6 point belts... If you are serious about being safe you definitely want to get a seat with a pass-through for the sub-belt or stick with the OEM 3 point belt. The reason 4 point harnesses are no longer allowed is that they are incredibly unsafe.

Here is a quote from the above Schroth document:
The forward pelvic movement will lower belt angularity, which can result in submarining. If the initial angle is not within the suggested range, submarining may result in severe internal injuries or death as the belt rides into the soft tissue above the pelvic bone the liver and kidneys. This scenario relates into a harness belt worn in a 4-point configuration.

All belts that have FIA homologation will be valid for only 5 years. After that point you can send them in for recertification and they will be good for another 5 years. For HPDE/TT expired harnesses won't prevent you from going on track. I've done about 15 HPDE events and I've never once had anyone check my harness (or seat) FIA dates. Of course, this changes when you get into actual wheel-to-wheel racing.

I use G-Force 6 point harnesses because they got the job done. The Schroth belt you picked out will get the job done as well. The more money you spend on a harness the more comfortable and easy to adjust it will be, in my experience at least. I'd also recommend thinking about a 6 point as opposed to the 5. It provides a little less pressure in the nether regions ;)

As far as the harness bar, I really can't speak to that. I installed a hard dog roll bar in my Miata that had a harness bar built in.

Simply basing it on the Schroth documentation it looks like you'd want to have a harness bar at the very least to get the belts attaching in the right place behind the seat. Whether that is a bolt in bar or part of a full cage I really don't know. I would guess that if it's for HPDE/TT a harness bar would be acceptable but WTW would require a full cage...
 
I know there's some things in SCCA Solo rules about possibly needing DOT legal harnesses. What's up with that?
 
Hey guys...blah blah blah...So a huge THANK YOU in advance for any help.

Seems like you're just going off a lot of hearsay from other people with this crap. Isn't there a NASA rulebook or something where you could find all your answers, then order the appropriate parts afterwards??
 
Thanks for the post, Will! Your setup is pretty badass. I'll read that Schroth page more tomorrow. I'm already crosseyed from trying to understand the NASA rule book...

Josh, a lot of this is hearsay because like I mentioned, the NASA rule book is a bit batty... If anyone knows legit answers and could explain them to me in Lehmans terms then that would be ideal. :)

I know there's some things in SCCA Solo rules about possibly needing DOT legal harnesses. What's up with that?

SCCA Solo Rulebook says this:

3.3.1 Driver Restraints
Seat lap belts are required in all cars, and must be installed in cars with
passive restraint systems that do not include a lap belt. Installation and
the use of shoulder belts or harnesses is strongly recommended, however non-factory upper body restraints may only be used in open cars,
cars with targa-tops in the open position, or cars with T-tops in the open
position when two conditions are met:
A. The roll structure must meet either the requirements of Appendix C
or the Club Racing General Competition Rules (GCR) 9.4.
B. The top of the roll structure may not be below the top of the drivers
helmet when the driver is in the normal driving position.

In the NASA CCR it says this regarding seat belts in section 11.3.2 and this is what is required for HPDE:

2. The driver and any passenger must utilize modern style* stock seatbelts in very
good condition, or a DOT approved restraint system, while operating a vehicle on
the track. Restraint system requirements are listed in Section #11.4.8. *Lap
belts used without any shoulder restraints are not permitted. Note- no four point
belt systems allowed after April 1, 2011, regardless of DOT certification or
approval, except that belts with current tags labeled FIA B-xxx.T/98 and meeting
FIA 8854/98 standards may be allowed with advance special approval. Effective
May 1, 2011, the only four-point belt systems that are allowed for use in HPDE /
TT are 1) those that carry an FIA B-xxx.T/08 certification, or 2) those that carry a
label from the belt manufacturer stating that the belts meet Federal Motor Vehicle
Safety Standard (FMVSS) 209 AND that the belts were designated for the
specific vehicle (e.g. For use only in BMW E36 models). Such label must be
easily visible to the NASA inspector.

Here is NASA section 11.4.8 which provides more detail:
2. The driver and any passenger must utilize modern style* stock seatbelts in very
good condition, or a DOT approved restraint system, while operating a vehicle on
the track. Restraint system requirements are listed in Section #11.4.8. *Lap
belts used without any shoulder restraints are not permitted. Note- no four point
belt systems allowed after April 1, 2011, regardless of DOT certification or
approval, except that belts with current tags labeled FIA B-xxx.T/98 and meeting
FIA 8854/98 standards may be allowed with advance special approval. Effective
May 1, 2011, the only four-point belt systems that are allowed for use in HPDE /
TT are 1) those that carry an FIA B-xxx.T/08 certification, or 2) those that carry a

Safety Standard (FMVSS) 209 AND that the belts were designated for the
specific vehicle (e.g. For use only in BMW E36 models). Such label must be
easily visible to the NASA inspector.

Section 15.5 basically outlines the minimum requirements of a harness and it's installation. If you follow the Schroth documentation you will satisfy those guidelines.

Thanks! :D I'm glad I can help you out. I'm pretty sure that some people were sick of me calling/emailing asking questions when I was going through the process so I'm happy to pass anything that I learned along.

And with regards to the harness bar thing, I don't see anything in the NASA CCR that prohibits you from using one.
 
Hmmm... So if I want harnesses for HPDE I will need 5 or 6 point belts. Which my Recaros can't use because they don't have the cut out in the bottom of the seat for them. Boo. But my friend wants to buy them so I can use the $450 towards legal racing seats that can use the 6 point harness. The HPDE rules don't mention any dates or regulations for the seats so a pair of Corbeau's should be acceptable.

And as far as the harness bar, if I can use the AMS/Sparco style bar then that would be better since I don't necessarily want to spend $600 on an Autopower rear roll bar right now. I also didn't see anything mentioned about harness bars.

My huge fear is that I spend $1000 on seats/harnesses and a harness bar and not pass tech inspection. That would suuuuuuuck. haha. So I'll keep doing research. Idealy, I would love to have everything mounted and ready to go mid-February for the VIR track day.

And the NASA rule book had this bit about appearance that cracked me up.
11.4.1 Appearance
All entered vehicles must be in good condition and appearance. Vehicles with excessive
body damage, primered body panels, etc., are not allowed. The vehicle must meet the
50/50 rule, which means they must look undamaged and straight at fifty (50) mph from
fifty (50) feet.

I think my car juuuuuust barley passes the 50/50 rule. lulz.
 
sub for good info

also if the harness bar is allowed i picked one up on ebay for pretty cheap and it was for a MR2, only thing you need are new bolts for mounting it to the seat belt bracket, the bolst that come are to long.
 
Yeah, that's the one I would snag, Fatti. The 47" one if I recall without the bolt-in ends.

According to a post from AMS they discontinued their harness bar anyway. It was stupid expensive too...
 
I skimmed the thread quickly, so I apologize if this has already been stated. If you are moving to 5-point belts, double check the rule books of the various sanctioning bodies for the events that you plan on attending. I know locally, 5 point belts are not allowed without a rollbar.

That being said, autopower makes a great bolt-in rear cage for the Protege and I think they do the protege 5 as well.

Good luck!

You'll be fine after Josh fixes the rust with you. I didn't know that was an issue until a potential buyer for my Miata said that they didn't allow Spec Miatas with rust on them. Seems like a waste of perfectly good cars (Spec Pinatas)...

The HPDE rules don't mention any dates or regulations for the seats so a pair of Corbeau's should be acceptable.

Based on the way the rules are written, it sounds like you can still find a 4 point belt that would be OK, but they are phasing them out. If safety is your concern it isn't really what you want anyway. 5 or 6 point is where you want to be.

For HPDE you don't have to have FIA certified seats or anything like that. Plus you might even be able to pick up a couple of out-of-date harnesses on the SCCA or NASA forums for a lot cheaper than new ones. Don't buy them if they've been in an accident though or show any signs of wear at all.

It's not that hard. Those Corbeaus and the Schroth harnesses that you linked so far would be perfectly fine.
