I'm in the same boat as you, I just tried to buy a clubman from IO Port, but they are on back order. They suggested this:

SFI and FIA. Any seen these before? Couldn't find much about them doing a quick Google search. I was going to do GForce, but now I'm second guessing that based on the reviews here.

I have my 6pt mounted just in front of the rear mounting "hump" using CAMS approved mounting plates. I don't know what size they are but they certainly look beefier than the large washers pictured above.

Also with the original (non-V) Sparco Sprint you can unpick a few threads holding the two sections together without cutting any of the cloth:

well, the "washers" go on the inside. there is still a required backing plate on the outside (bought/made separately). G-force plate is 4"x4". Scroth's is 4"x2" and has a nut welded on it.

Don't get me wrong - you can do a lot worse than the G-Force belts, especially at $179 or whatever they cost. For a budget belt, they do a great job, but if you are willing to splurge you'll notice a big difference between the G-Force belts and the Schroth belts.

Put it this way: If you are serious enough to have a HANS device, grab the Profi II-6H belts. Otherwise go with the G-Force belts and sell them for ~75% of retail in 2 years when/if you upgrade.

BTW - We only use pulldown belts. The pull-up adjusters are strategically placed to interfere with the seat in pretty much every Miata I've ever seen. I run the extra belt out through the lapbelt holes, then back up, and they turn into pull-ups then.

^+1. Its good to start off on. Its not a bad harness, you are generally paying for harness size (2" or 3"), weight, camlock mechanism, and the certification.

Its generally cheaper in the long run to go with a 5-year cert. belt (for example, clubman $200 for 2-year cert. but the avg. profi is $360 for 5-years, you can do the math), but since this is the first harness I am buying, I wanted to have the chance to change it out for something else in case I don't like it. It also gives me the chance to get rides in other people's cars and see how their harness of choice, which will help with future decisions.

With that said, I rode in a miata with G-force harnesses and they worked great. Just rubbed on my shoulder some (but they all will unless you get the padding).

The G-Force 6-point harness is the only one I've had (blue one in the photos on page 1) but I've been fine with it. There's been a time or two where the shoulder strap itches the side of my neck but I just adjust my shirt. Almost no issues with the sub-belts interfering with my junk; only one or twice I had to readjust. I'll give Schroth a go next time around.

oh, well I was going off there Harness Install instructions, but I guess they could be making a different 2 year belt:
http://www.gforce.com/pdf/Harness_Install_Info.pdf

Anyways, the Clubman at least is a 2-year cert.

You can get either with a 2-year or 5-year tag. The difference is SFI vs. FIA. Same belt usually, you're just paying for a different tag.

Belts were delivered and installed today. Kudos to FedEX for delivering on Saturday, and/or SafeRacer for shipping a Saturday deliver option at no expense to me.

Anyway, the sub belt is long enough to wrap under my thighs and out the lap belt holes and anchor to the lap belt points. And as far as I can tell, that is an SCCA approved mounting scheme. However I ended up carefully opening up a seam in the front of the seat (as suggested by a previous post) and ran the sub belt through it. It's still anchored at the lap belt mounting points. I used eye bolts and have the lap belts and sub belts each on snap mounts. The shoulder belts are bolted to the roll hoop with class 8 1/2" bolts.

Other than wanting to put some pads on the belts, they seem fine. We'll see. Oh, they have a 5 year tag.

+1 for harness pads, makes the cheaper belts feel great, especially if you put the more expensive pads on. I have Willans pads on my G-force, and G-force pads on my passenger side. Big difference.

Unless you plan to use a HANS (or similar device), then you should get this:

The doubles have two shoulder harnesses, and usually for racing regulations.

Question

Oh, hey guys. Just doin' a little grave diggin'.


After spending some time searching in this thread and others, I am about to pull the trigger on two sets of the G-Force Pro 6-point camlock harnesses, in the pull-down variety. Where I am confused is on the mounting hardware.

The images for all of the various harnesses show standard bolt-ends. I am getting thrown off a little by RayvnX's post and talk of the eye bolts and clip-in bolt ends.

Am I correct in understanding that you replace the standard bolt ends with the clip-in bolt ends to use with the eye bolts? Is there a reason not to just use Grade 8 bolts with the standard bolt ends?

Or do the belts not actually come with any bolt ends and the pictures (of the harnesses) are deceiving?

This is on a pair of Sparco Rev seats, factory floor seat mounting brackets/bridges still in place. Driver seat is on a slider, the passenger seat will not be.

I recently became aquainted with safecraft belts. You have to call them their website is completely useless. But they will make belts custom to fit your car. I have no idea on price, but honestly this falls under the same argument as the schroth stuff. Just have a look.



If I for some reason ever end up owning a formula car or a car that would go on a track, pretty set on buying these. Failing that scroth, because they're also amazing.

G-Force belts to come with normal bolt ends. Do you notice how far off the car he has the eye bolts?

Speaking of G-Force belts. I've only ever used older ones but the cam locks suck, never reset all the way. And on rare occasion get quite stuck (in the un-locked position thankfully). I'd rather go with crow at the price point.

I wouldn't bolt the bolt in brackets to the floor. If you are ever in a collision, the force would be normal to direction the load was designed to be applied. You can remedy this by purchasing the snap ends and an eyebolt that allows the sub belt to load in the intended direction.

Alternatively, I think you can use a u-bolt with a substantial backing plate if you're deadset on using the bolt in brackets. I would mount my harness this way if I was out of options, but it is easy to switch to the snap clip.

just my .02

I'm using G-Force and they come with regular eyes for bolts. I used the stock NA lapbelt hole for the outside lapbelt, drilled a hole for the inside one in the tunnel, and drilled for the other three as well. I used large steel backing plates behind every drilled hole (4x4 or 3x3, depending upon location) and thick grade 8 washers.

I am certain I would be killed by the force of an impact long before it reached a level of force in which the mounts would be ripped loose.

You used to be able to specify snap in or bolt in. I guess they standardized to bolt in now. You should still be able to purchase 2" and 3" snap hooks separately, but the price may get you towards what you'd spend on a higher end belt that comes with snap hooks.

I used eye bolts and snap hooks for the lap and crotch belts, and standard bolt in rings on the shoulder belts. I recall having to drill a hole for the passenger, inside lap belt. I used stock mounting points for both outside lap belts, and installed the driver, inside lap belt eye in place of the stock rear o2 sensor wiring.
