I put an OMP harness in my car last year, it is fantastic. Would definitely recommend it. My UltraShield seat is okay, too, although I wouldn't say that it is amazing or anything; it gets the job done.

+1 for cobra suzuka. I love mine. I'm also a fan of schroth profi belts. I've got 6 points for driver and pass in my car. My driver side is a 2 inch lap belt 3 shoulder belt version and the lap belts are pull up. Passenger side is 3/3 and pull down.

2" lap belt pull up harnesses = win. Everything else is poverty level (to steal a page out of the book of hustler) uncomfortable.

Since I saw them mentioned earlier in the thread... latch and link had its day in the sun, but there are now SFI approved camlocks for $100 for the budget builds. There's no reason to use that dinosaur tech any more.

+1 for the Schroth Profi stuff. I have the Profi III Hans, another good deal I lucked out and stumbled upon, didn't know how good they were when I found them. Now every other car I get in with belts from a different mfg feel inferior and frustrate me haha. They spoil you.

The good part of a latch and link is that it will never pretend to be latched and will always unlatch, you cant really say the same thing about a $100 GFarce.

I've got latch and links. It's what I started out with in aviation decades ago and I trust it. So, maybe I'm a dinosaur?

Not saying they don't work well enough in a crash, they're certainly proven in that regard. But I'd never want to have to use them every time I got in and out of my car. I bought a miata last year to flip, budget-track build sort of car, and it had a latch and link. Drove it around a few times during the time I had it and never got used to how clunky and old-school it all felt.
Comparing the low-end SFI camlocks may be a bad choice, I don't think I'd ever choose to use a G-Farce (lol) either, the direction of thought in my mind is more that if you look at the proper camlock systems out there now, with all the details and thought put into them, there's so many things that contribute to both a nicer user experience day to day as well as a safer and more comprehensive system for all of the variables of a crash, that latch and links just look seriously outdated in comparison.

One of the main things I like about the schroth belts are that the cam locks are on the sub belts. I assume other manufacturers do this as well but it's a nice feature.

I havent seen one mentioned yet, but I have a Sparco EVO. I love it. Super comfy for double duty. I daily'd with it for almost two years early on. We have cheapo Kirkeys in the autoX car. They do what they need to, and aren't totally uncomfortable with the foam pad/cover.

Schroth built, Sparco labeled harnesses in my car. 3"/3" camlock. +1 to everything said above about Schroth quality and camlock convenience.

G-farce in the Autocross car. I actually use them alot more than my Schroths because of the in/out/in/out nature of co-driving autoX and they arent bad. For less than half the cost of my Schroth stuff, I would probably buy them again for a similar project.

The question of aluminum seats safety was brought up. Aluminum seats bend as they absorb the energy from a crash. Fiberglass/carbon FIA seats do a better job of absorbing the impact, and will do a better job of keeping your head and shoulders in line. Your body can absorb a large amount of G forces if you keep your head and shoulders in line.

If you are going to run an aluminum seat in i would highly suggest gusseting it to the roll cage/bar in as many places as you can. We strongly recommend you avoid back braces similar to this one. we have had reports of individuals going into a wall backwards with these seat braces and suffering major spinal cord injuries.


^ this video at 0:30 shows a crash in a aluminum seat and how that seat bends.

Racetech has some very igood information on FIA rated seats

Ok I will play.


I have two Sparco Pro 2000 seats (different versions/years) that came with my 91. One has a 6pt harness and one does not (passenger). My goal this winter is to swap the seats (passenger is larger). I would like both to have a 5pt or 6pt setup, it just seems like the way to go with the roll bar.

I would like to get a harness that is easily adjustable for my passenger. My current 6pt harness has shoulder adjustment, but doing the lower belts is a PITA. I like the idea of having something that the passenger can adjust when they get into the car. If my bank account is nice to me, I might replace my driver's harness as well. Nothing is wrong with it, but I am thinking black might be a better route, as it draws less attention when I am on the street.

Any advice on what you have?

Thanks for those vids OG.
The back brace in the Racetech vid is a good, simple design that at least personally I'd consider the mandatory minimum for any aluminum seat. It's a shame that most rulebooks don't go into any detail about back brace design - and the result is the kind of cheap/easy to mfg/easy to install brace you mentioned there that doesn't cut it being used all too often.
I also like about that vid that it shows a properly designed back brace has a place even on a composite seat, it's not just a band-aid for out-of-date seats.

Since my Sparco Circuit is now out of date I've had building a back brace on the very long to-do list, I'm going to move that up the list and get that done.

Wow I didn't even notice the first time watching this because the vid quality is poor, but the shoulder tab and the halo both bend completely 90* and allow the driver's body to end up on the passenger side of the car. Seems to confirm all the gut bad feelings I've had about those when working with them. No thanks.

Can anyone expand on this? I have an fx1 pro on the way, I have side mount brackets, and was going to just bolt the side mounts to some steel and bolt the steel to the floor.

I read up on the Targa install of hte FX1 and I figured if it fit in an NA it would probably fit in an NB.

EDIT: You'll forgive me for not considering the clubroadster seat thread a source of authority on the matter..

We always recommend a FIA harness. They expire in 5 years instead of 2 years(SFI harness) . In the long run it is less expensive to use a FIA harness. if you're looking for easy entry and exit we would recommend a harness that has aluminum adjusters. Tightening and loosening action is silky smooth. The steel adjusters have a tendency to have some resistance, especially when new. out of the brands we carry - simpson, OMP, and sparco all offer aluminum adjusters. take a look and see what fits your price range. www.ogracing.com/car/harnesses

In a miata, avoid any pull up harnesses. They have a tendency to be too long and unable to secure you properly in our small cockpits.

In our miata we run the Simpson formula harness. It takes awhile to get buckled in, but once your secure it is very comfortable.


Due to our miata's use in auto cross. the constant in/out/in/out we need something that is faster. we will be replacing the current simpson formula with the sparco fia 6 point.

The FX1 has a very wide base where your legs exit the seat. the wide leg opening forces the shoulder area into the door. in a miata a BFH is needed to make it fit properly. I had a chance to see keith's car at the mitty this year. i have no idea how he got those seats mounted without cutting the fiberglass.

we had a fx1 in our miata before we went to a sparco Pro adv. we had to cut up the fx1 quite badly to get it to fit. now it serves as a video game chair.

Thanks for the tip about Advanced Autosport. I like supporting SPS since they are local but not if it means it takes 11x as long to get something to my door.

What I really want is whatever Emilio had in Crusher circa 2012. Super comfortable and tons of leg and headroom. I'm certain just one costs more than both of my seats combined though.
I ordered an ultra shield sm from solo performance in March and it took 12 weeks

I fell in love with these seats... and then I looked up the price per seat. Then I cried and started looking to see if any miatas showed up in the junkyard with leather :/

Is there a specific line of harness that has adjustable mid and lower belts that are easy to access. My current 6pt harness you have to spend a good amount of time under the seat and on the sides of the seat to adjust the belt length. I am not sure if they exist but I would love to have something that is easily adjustable near the center connection point, which would allow for adjustment in a min or two.

Thanks for the advice so far.

Thanks for the input on the FX1 pro.

It's funny, once upon a time, the thought of hammering or cutting or drilling my car was terrifying. I installed my first rollbar and it scared the bajeebers out of me to cut my parcel shelf and drill holes.. and I tried to do everything as minimally as possible.

Then I swapped out rollbars on a few cars, and turbo'd my car, and now it's like "wait, you mean all I need to do is hammer on my transmission tunnel a bit, and drill some holes in my floor? What's the big deal?"

At the begining of the year i bought a pair of Schroth Profi 6 point. Meanwhile i have not instaled them

Main reason is that i have Lotus Elise SEATS on my car and need to open the holes for the harness. But since the Elise seats donīt have enought support i think i am going in the corbeau direction.

Anyone around here have this ? Corbeau LE-X

I really like my seat, it's made for sedan though. Sparco Pro-ADV, require some time to fit it properly in the car and we made custom steering mount from the cage. FIA was mandatory and halo a big plus for me. The car don't really see public roads...

I was to buy sparco HANS with titanium turnbuckle but I tried some Racequip and was sold. FIA, magnesium turnbuckle, aluminum adjusters, pull up lap belts and HANS 2" webbing and all this for half the price compare to sparco's.

Happy man, far from Sparco Roadster seats and G Force harnesses that we're in there before...
