Harnesses with factory seats
Wasn't there a big thread regarding this?
What was the tldr version? https://www.schrothracing.com/products/tuning |
TLDR Version: No
|
Do you like negcats? Because using a harness with stock seat is how you get negcats. Schroth harnesses designed to work with OEM seats list the model they're designed to work with. You won't find a Miata in that list.
|
The point of harnesses is not to die. If use harnesses with stock seats you might die. Therefore don't use harnesses with stock seats.

Might as well get a cheap stage 3 clutch off ebaY while you're doing stuff

Harnesses will not stay on the stock seats and will do bad things to your back in a crash. Plus, the stock seats are about a supportive as my mother when going around a hard turn and a harness wont fix that.

I'm sorry that your mother doesn't tell you what a good job you do on a daily basis.

Everything I've read here says that four point harnesses are dangerous, and full harnesses without HANS are dangerous. These setups lack sub straps and HANS compatibility.
It seems clear that they wouldn't be nearly as safe as a "real" harness setup. It's possible that they're safer than stock seatbelts, but unless they do the full NHTSA crash testing regimen (which seems unlikely), we'll never know. Sometimes good companies do dumb things when they want to expand market share. |
Simple lesson is;
Stock seats = Stock harness, G-lock and foamectomy will help. Race seat = Properly mounted pull up race harness w Hans. Note: Race seats don't recline. It they are advertised as reclining race seats, they are actually street seats the advertiser is lying about and you shouldn't believe anything they advise after that. |

Just make sure you buy a cusco roll cage too. Otherwise you will die.

OK if the objective is to not slide around as much, then a reclinable supportive ("race"...not) seat with stock belts is a good step up and not less safe than factory everything?
Then the next step up from that is to add a harness, then some kind of HANS device, correct? Is the problem with reclineable "race" seats, that they're not as strong in a crash as a real bucket? |

See also accidents with ebay race seats and harness bars with other makes of cars. Also take note of what aftermarket steering wheels look like when your body makes contact with them.

I have been using the CG Lock with my stock seats/belts on track, and it helps. I'm having fixed race seats and harnesses installed as I type, and will be swapping between those and stock for track/street.

OEM or other reclineable seat + OEM 3-point belt + OEM airbag suite (frontal + side)
OR Fixed-back race seat (preferably fiberglass FIA or better) + 6-point SFI or FIA harness + SFI or FIA HNRS No mix and match, no exclusions. |
About as useful as tits on grandma

OK so 6 point harnesses will not work with a reclineable "race" (not) seat.
What is the lethal failure mode of said reclineable "race" seat in a crash, if used with a 6 point harness that's attached to the car's chassis / harness bar? (assume said seat has shoulder strap holes at the right height, which AFAIK is *below* the shoulders, right?) |
