I almost bought these but decided to check in here first to see if I can even use them on the track. Car is a 2008 M3. Brand is Schroth Quick Fit 4pt Harness. https://www.schrothracing.com/products/quickfit#3366. Thanks in advance.

That's why you are up there and I'm down here. Thank you. Kinda cleared it. Restraints have the necessary certifications but it may not have the right configuration? One section seems to allow it, another says it no good? Oh well, I guess just roll with the factory seatbelt.
Thank you for the info

If you stick with the seatbelts, look into a device called CG-LOCK. Works good. I used it till I was ready for a 5-pt harness (much better than a 4 pt) and race seat.

I'm pretty dang sure Four point harnesses are not permitted as per the CCR. There has been instances of drivers being partially ejected from the seat in a roll over. Safety first, get the safest seat and harness system you can afford. You're not replaceable everything else is. You'll have better control driving not having to brace yourself while braking and cornering.

They are allowed, if they are the correct specification if I'm reading 11.3.2 correctly.

even the part that states "AND that the seat belts were designed for the specific vehicle"?
the quickfit claims it works on your model car not that it was designed for your car.
Let's try this again...
there has been incidence's where a drivers were partially ejected from the vehicle in a roll over.
it doesn't end well.

Not sure what you're seeing, but here is the rule.

11.3 Required Safety Equipment - Driver
Disclaimer: Conformance to these regulations is the driver’s responsibility. These regulations do not guarantee
or imply that injuries or death will not occur. If there are any questions or problems with these regulations it is
the reader’s responsibility to contact the NASA office, or a NASA official immediately.
All participants shall utilize equipment that meets or exceeds these minimum requirements, while driving on
track (Note- passenger equipment must meet or exceed these minimum requirements; but do not necessarily
have to match the driver’s equipment):
1. Use a proper fitting helmet that meets Snell 1995 2000 (SA1995SA2000; M1995M2000) or newer (or
equivalent) standards for cars or motorcycles.
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.

3. Non-synthetic fabric clothing (i.e. cotton).
4. No open toed shoes, or tank tops may be worn in the car while on track.
5. Drivers should wear eye protection such as goggles, safety glasses or face shields preferably made of
new impact resistant materials.
6. It is recommended that any corrective eyeglass material used be made of safety glass type that meets
U.S. Government standards

If the quickfit complies with 11.3.2, then they are CCR legal. I see they are "designed for the vehicle" part is met, but I can't confirm the FIA or not however.

Not sure what your point is. Are you saying a 4 point is less safe in a rollover than a 3 point?

Oh, and don't be an internet jerk with your "lets try this again" crap. We are all here to help each other and learn. Want to be an internet hero, there are other forums you can visit with that tude.

apologies...
I think you'd have the same "tude" if you witnessed a 4 point harness partial ejection that didn't end well.
doesn't meet FIA.
My point is to the inquirer.
Safety first. Proper seat and harness before a new set of wheels.

A little of my background. I am an HPDE instructor, race license holder (last 7 years), and support races as part of the fire/rescue safety team (since 2001). I have seen a lot more than you can imagine.

In my opinion a 4 point isn't any worse or better than a 3 point in the situation you describe. Not an expert mind you, just my opinion. That said, I agree with you that a 4 point isn't a great solution, I personally wouldn't use them. If you want better harnesses, go 5+ point, proper seat and a roll bar. Trouble is, a rollbar is dangerous on the street without a helmet. It's a tough call for most of us.
