Seat belt harness with stock seats

[Ducatijay]

Wouldn’t pass inspection here. That is dangerous. Worse than oem 3 point. You are a big boy. Do what you want with your own body. Odds are you will be fine. But it is neither proper nor safe.

Why are we still doing this? It will pass at any regional or national SCCA autocross. Again, I can't change the drivers seat in street (stock) class.

THIS IS NOT FOR TRACK EVENTS!!! Even though I see plenty of "track cars" with race seats and 5/6 point harness without proper rollbar or cage and no Hans device. I've even seen harnesses bolted to the seat. Those aren't safe nor proper.

Maybe we can have a political debate now......

Buy a seat and a proper harness. Anything else is a hack.

if it's just autocross with no light poles/other cars i might be willing to use this:

Perfect. Thanks

I have personally watched a Porsche GT4 spectacularly lose it at an autocross, taking out a jersey barrier (head on) and totaling the car.

Autocross is still a motorsport, and shit still happens. Be safe out there everyone.

Maybe we can have a political debate now......

more importantly, we need to discuss what oil you run in the engine…. And have you ever owned a corvette?

“Guys I’m looking for an answer to something I already have an answer for and I will ignore all input you give me.

Also, even with my utter lack of understanding of safety, I will lecture everyone on safety, and call out how everyone else is doing it incorrectly.”

Safety first! Just kidding, coffee first, safety is like 3 or 4.

Dude, are you ok? Did your domestic partner leave you again and now you're lashing out?

Read my question again. I never asked your stellar opinion. And I never wanted to start a debate about safety.

It is literally the #1 thing with any auto sports event if the event is ran by people with brains. Safety for the driver and everyone else is KING over everything else. If you want to stay in your class with a stock seat use the oem belt. There is no need for a harness for stock class. If you're fast enough where you need a seat harness then you shouldn't be running in the cars stock class it's that simple. Nobody on here who tracks or runs tons of autocross is going to suggest a harness for the simple reason @razorlab has reiterated to many times already

I guess we are "still doing this" because you keep responding
AND
more importantly as these threads are stored and can be referenced later by others, I just want future others to know this set up is NOT safe nor legal in SCCA. I do not know how that would pass? No submarine protection, cant use seat as anchor point. pic shows something wrapped around the head rest?

Cut and paste from SCCA:

Seat belts All drivers in SCCA sanctioned speed events shall utilize either a 5, 6, or 7 point restraint harness meeting the following specifications.7 point restraint harness is recommended. Arm restraints are required on all open cars including open Targa tops, sunroofs and T-tops. Arm restraints shall not be worn in a manner which limits the ability of the driver to provide visible signals to other competitors while on track. The shoulder harness shall be the over the shoulder type. There shall be a single release common to the seat belt and shoulder harness. When mounting belts and harnesses it is recommended that they be kept as short as reasonably possible to minimize stretch when loaded in an accident. The shoulder harness shall be mounted behind the driver and supported above a line drawn downward from the shoulder point at an angle of 20 degrees with the horizontal. The seat itself, or anything added only to the seat shall not be considered a suitable guide. Guides must be a part of the roll cage or a part of the car structure. Only separate shoulder straps are permitted. (“Y” type shoulder straps are not allowed.) “H” type configuration is allowed. The single anti-submarine strap of the 5 point system shall be attached to the floor structure and have a metal to metal connection with the single release common to the seat belt and shoulder harness. The double leg straps of the 6 point or 7 point system may be attached to the floor as above for the 5 point system or be attached to the seat belt so that the driver sits on them, passing them up between his legs and attaching either to the single release common to the seat belt and shoulder harness or attaching to the shoulder harness straps. Each seat (lap) and shoulder belt of the harness (5, 6, or 7 points) shall have an individual mounting point (i.e. 2 for seat belt and 2 for shoulder belt minimum). 6 or 7 point system anti-submarine straps may share a mounting point with one or both seat (lap) belt(s). The minimum acceptable bolts used in the mounting of all belts and harnesses is SAE Grade 5/Metric 8.8. Mounting hardware, including eye bolts, as provided by the belt manufacturer, may also be used for mounting belts and harnesses. Where possible, seat belt, shoulder harness, and anti-submarine strap(s) should be mounted to the roll structure or frame of the car. Where this is not possible, large diameter mounting washers or equivalent should be used to spread the load. All driver restraint systems shall meet one of the following: SFI specification 16.1, 16.5, or FIA specification 8853/98, 8853-2016 or 8854/98. Restraint systems meeting SFI 16.1 or 16.5 shall bear a dated SFI Spec label. The certification indicated by this label shall expire on December 31st of the 5th year after the date of manufacture as indicated by the label. If for example the manufacture date is 2014 the fifth year after the date of manufacture is 2019. Restraint systems homologated to FIA specification 8853/98 and 8854/98 will have a label containing the type of harness designation (‘C-###.T/98 or D-###.T/98) and date of expiration which is the last day of the year marked. All straps in this FIA restraint system will have these labels.



Again, if you run in a group that allows that somehow, godspeed you are an adult and only potentially hurting yourself.

Can you circle the part about not using a oem seats?

So if I'm fast in a stock car, I should not run a stock class? Got it. Makes sense. I'll bring that up in the next world meeting.
