I want to do road coarse events,probably once a month if time permits.

I don't really have a lot of faith in the stock belts at high speeds, but it's probably all mental.

I want to get 3 or 4 point restraints for my car and the forum for autocross/road racing has very few posts. So I hope that someone here can shed some light on things...


Corbeau has some 3 and 4 point harnesses that appear to be able to bolt in or attach via eye-bolts etc...

Simpson has almost the same thing but looks like it wouldnt work too well with the stock seats unless I got the Y-belt setup.

I'm not looking to be certified to race full out, just track days and normal events that arent hard core.

Has anyone installed aftermarket restraints in their new Mustang? If so, what are your recommendations?

Suggestions or advice?

I'd really like to avoid buying racing seats for a daily driver... i'm just looking for a little more belt to hold me back in the seat.

Thanks
Jake

Just make sure you check out carefully whatever santioning body you decide to race with cause many require 4pt and even 5pt. Make sure to get the rulebook for that sanction to be sure.

I put a 5pt system on my stock seats just fine. I have a roush car and liked the roush seats and didn't want to lose them for the extra weight shaving.

 

I spoke with a friend who does road racing / track day events and he has and likes www.schrothracing.com harnesses.

I bought the Rallye 4 ASM belts.

You mount them to the factory seatbelt points and in the rear it has a DOT approved disconnect seatbelt type attachment that allows you to disconnect the harness and use the rear seats. This still allows you to use the factory seat belts if you want to.

they are Dot approved and he says a lot of the guys he goes to events with use them. It's probably not full on die hard go every weekend type equipment but he said it should be good for me since i'm not doing full on racing and I wont have to buy a seat.

any input?


thanks,

I think it would be interesting to see them on the stock seats.

 

When they arrive, I'll install them and take some pictures and post. Apparently they are designed for use on stock seats only if you have two posts on your head rest (they fit between the posts). Their instructions do show them on a seat with one post, but I dont think thats as common these days.


Can't wait to read the service manual that arrived via ups today ...

 

I am of the logic that it's not smart to install harnesses without rollover protection. Harnesses hold you upright and if the roof collapses, it's not going to be fun.

 

I have to agree with you. Someone at our local track rolled a 340 duster 3-4 times this year and the roof was touching the steering wheel. If he was in a harness he'd be dead. Do not think for a minute that I believe being unbelted would be better. A 3 point belt is probably the best for a car without rollover protection.

 

Well if its like Solo I, I would think you would have to have and want a basic roll bar ... not a full cage but a primary bar with back braces. Its your head so the risk decision may or may not be your choice.

Whether you do the bar or not, with a full shoulder harness set up what is critical is getting the anchor point high enough. If its below horizontial you can expose yourself to back injury if you run into something. This is because there is a load componet going straight down that will add compression to your spine. While tempting, your seat is not designed for such forces. Accidents do happen on the track.

Enjoy.

 

I agree, shame someone does not make a functional rollbar (not a full cage, just a 2 point should do) to add just a level of protection (kind of like the 68 shelby did)

 

It would be nice to have a roll bar behind the seat that could be taken out when not on the track... but I've not seen anything like it.

aesthetics are nice for a street car that sees track time.. so it would have to be somewhat oem looking....

Does DOT approved mean that they have taken into consideration the back problems? www.schrothracing.com belts are DOT approved.

any thoughts on them?

 

I have RCI 5 point harness setup.
I used the two factory seat belt mounting points, used a bolt through the floor pan for the center belt and the two shoulder belts anchor on the rollbar crossbar anchor point.

 

They are an appealing design. DOT means they meet or exceed the minimum design standards established by DOT ... likely strength and elongation.

Setting yourself up for (or avoiding) back problems is simply an installation issue, nothing to do with DOT. Shoulder harnesses are meant to keep you from moving forward, not moving up ... that is what the lap belt does (as well as keeping your hips from moving forward). Optimum shoulder harness installation results in the harness line of action being above horzontial. This reduces the compression your spine might see. If you ran you anchor all the way to just under the rear window glass, the angle might not be too bad. Not too god for someone sitting in the back seat 9not that the back seat is all that inviting anyways.

The Shelby style might work if you ran the vertical members to the floor pan (anchor it there) thru the rear seat arm rests, and then anchor the bar at the existing roof shoulder harness anchor point as well. That would be effective and strong. Then you could anchor your shoulder harness and inertia reel just like the Shelby's used to.
