CG Lock or 4 Point Harness

The Schroth 4 point per the call I just had is certified on the S550 mustang so they are good to go with Nasa.

I will confirm when i get the belt

Did you specify the Quick Fit /QF Pro? I know the belts are FMVSS 209 in the S197's, but I don't have paperwork showing they have been certified on the S550. The belt itself shows the FMVSS 209 on the ASM cover, I just don't have anything other than that to prove it's just not a S197 belt in an S550, if that makes any sense.

I believe that is all that is needed to be legal in NASA for these belts, the FMVSS 209 cert.

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. Lap belts used without any shoulder
restraints are not permitted. Restraint system requirements are listed in Section #11.4.8. The only
four-point belt systems that are allowed for use in HPDE / TT are 1) those that carry an “FIA B-xxx.T/98
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.​

Note- four-point belt sets that have a DOT-only certification are not allowed.

Pro belt, The regular QF you cant use a Hans device. The tech said they are labeled to include mustangs through 2017.

Scrotch racing 4 point is FIA B-xxx.T/98 but then you need a bar per NASA

Per the rules below just being DOT isnt enough. Nasa also said this in a email

Ok, that's what my gut was telling me was the case with the QFP. I believe I was just waiting for Schroth to publish the year/make/model specification for the belt for it to be good in NASA HPDE. Good deal.

That's sort of what I remember, but the latest rulebook seems to say otherwise:

11.4.8 (HPDE) Any harness or any restraint system, other than factory stock, shall conform to CCR section #15.5, in all respects except for the expiration regulations.​

15.5​

​

​

​

Driver restraint system​

1. All vehicles should have a five (5), six (6), or seven (7) point seat belt system.​

So stock or 5, 6, or 7 point (with race seat and roll bar?) with nothing in between.​

Hmmm

From NASA current rules (https://nasa-assets.s3.amazonaws.com/document/document/282/2017.8.pdf)

Section 11.3
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. Lap belts used without any shoulder
restraints are not permitted. Restraint system requirements are listed in Section #11.4.8. The only
four-point belt systems that are allowed for use in HPDE / TT are 1) those that carry an “FIA B-xxx.T/98
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.
Note- four-point belt sets that have a DOT-only certification are not allowed.

And I emailed NASA and confirmed they would accept the belts

It's very bad rule making when 11. 3 and 11.4.8 (all of 2 pages apart) say opposite things.

Harness arrived! It says valid for all 6 gen mustangs!

Installed

Looks great. I will have a set before my next track day.

Wonder if I should get one for passenger side (for instructor), too.

At 500 each I passed on the instructor. If I have one Ill just use the stock belts

Thread bump..

Has anybody used these for NASA HPDE events with success..?
Were they tech approved.? Pro only.?

I looking at the 4 point for my next trackday upgrade. Probably going to make a trip out to Schroth near Charlotte, NC for review and fitting in the not too distant future.

Isn't using 4 point harness putting you at a greater risk due to "submarining" in case of a crash? Also in case of a roll-over you'd be in a bad situation if the roof collapses since you can't lean to the side and have no roll bar to protect you.
