DIY Schroth ASM Harness install

[Optimum Performance]

Please do not use the Child seat anchors. Unless you are the mass of a child. Either use the seat belt buckles of the rear seats or place clips to the seat belt anchor points. As far as the seat belt tensioner issue. You are attaching a racing harness to a solid mounting point. No need to drag pre-tensioning into this. If using stock seat belts they still function properly. If using racing harnesses you should have them just tight enough so they are slightly uncomfortable. There is nothing misleading about what these harnesses intend to be used for. My Mustang was the Mustang used to initially prove these 5th Gen belts would work in a 6th Gen Mustang.

I agree, there is nothing misleading about what they are used for, your just missing the point. I’m sure mine will function just fine. But it is used as a selling point, why even advertise something that is clearly not true.

Selling point that it retains the use of the factory safety systems you are not defeating.

No Tommy, They state “Take advantage of”, not “Retain”.

The quotes in my original post are exactly what they advertise.

"Racing is dangerous" User assumes all risks. This is a thread where people are mounting the shoulder harness to anchors designed to retain a 75 pound child mass upon impact. No one has an issue with that except me who happens to work is Professional Motorsports but we are bitching about advertising claims...

Look, you are trying to locate yourself in the seat so you can control a vehicle under high g forces so you can maintain control. These harnesses, when properly anchored will allow you to do that. The fact that American Muscle just copies and pastes information from HMS to their website is not my concern. We have several customers running all brands of restraint systems in dedicated and dual purpose Mustangs, there is no lawyer language involved. You are responsible for your ultimate safety. Stay in bed.

Hey if you have an issue with installing these call the person you bought them from to guide you through it. We do that for our Customers.

Again Tommy, you are missing the point.

No need to get hostile about it and tell me to stay in bed. It’s used as a selling point and I have seen others make the same mistake and regurgitate the same misinformation.

It may not be important to overall function but those that still trying to decide on what different products they could choose from may want to know about the particular statement advertised about these. I know I would. That doesn’t mean they don’t work. I never made that statement. I have no issue installing these, never said I did. It is of no concern of yours then, but the only one making an issue at this point is you. Seems like your just trying to pick a fight here. So not going to discuss it with you any longer.

It’s bad advertising, get over it.

I did recently however get the BG trans and rear fluid change kit along with some shims and RBF from Optimum. good stuff, as advertised, “thankfully”. And fast shipping too

Anyways sorry to everyone else who is just looking for some info. as I was. It was the first thing I noticed when diving into it, and wanted to understand just how it was supposed to work as advertised. So here I am, and realized it does not... Some professional motor sports people may not care when spending 800 on a set of harnesses in fact they would prob be spending a lot more on just one, paid for by their sponsor, installed by their crew, and the safety stuff has been stripped out. But maybe a few others out there, who like to track there car now and then, or more, do care and want to know just what it is they are getting for their money.

These belts have been around for longer than the 6th gen Mustang. That pre-tensioner language was probably correct for whatever car they were originally made to work with. Its a lazy omission that the Ford was added to the list w/o correcting that language. You should email them!

While the advertising language for the Quick Fit should be corrected, but the belts are still a perfectly useful product. Like ALL harnesses, they must be manually tightened correctly to function.

They're incredibly helpful in keeping the driver planted in their seat, able to feel what the car is doing w/o struggling to stay put. When the event is over you can quickly and easily revert back to the stock safety belts and systems. Its night and day versus trying to do any serious performance driving with the stock belts while flopping around the cabin.

The additional feature of the Quick Fit (which is also possible by plugging in the stock belt behind the seat with the Rallye-4 harness) is you retain the stock airbags function which is desirable with the stock-like crash performance of the ASM system. With a true 5-6 point harness you hopefully won't go anywhere near the airbags, but the ASM system allows the belt to give on one side, like a stock 3-point belt, so keeping the airbags working is a good thing. I'd rather have a 6-point in a rigid seat and a HANS device for a track car, but since I daily the car, the Schroth belt combined with stock airbags seems like an ok compromise.

Updating this to included installation into a 2018. A few things to be aware of-

1. Installation of the anchor on the front/inboard side will most likely result in the factory receiver's mounting stalk rubbing against the center console.

2. Installation of the front/outboard strap will require substantial removal of plastic trim around the area of the factory mounting stalk (more than just a "relief" cut). I recommend removing the rear trim panel in order to make a clean cut and dress the cuts properly.

3. Tailpiece can and must be mounted to existing factory seatbelt mounting locations in the rear seat area. Nothing problematic with the belt by doing it this way and certainly much safer than going for the child seat tether points.

4. Schroth does not provide enough length for the rear/inboard strap (anchor to adjuster length) and as a result, the adjustment buckle barely sticks through the rear seat cushion. In addition, there is not room for both Schroth adjuster and factory receiver to both make it through the cut-out in the cushion. It's one or the other and I chose the Schroth.
