was not sure if only in dragsters and roadsters.

Used them in my Grand National only thing I needed to do was make a loop on cross bar so they couldn’t slid because I had factory seats if I had a race seat that it went threw a hole would’ve been fine tech told me

Exactly. My belts just go over my shoulders instead of through the hole in the seat. On the cross bar, I have two hoops that keep the belts in place. This just keeps them from sliding down the crossbar so that they stay behind the seat. That's all that's required.

DRIVER RESTRAINT SYSTEM
Seat belt mandatory in all cars. Driver restraint system meeting SFI Spec 16.1 mandatory in any car running 11.49 (*7.35) or quicker, in convertibles running 13.49 (*8.25) or quicker, and
all dune-buggy-type vehicles running 12.00 (*7.50) or slower. SFI 16.1 restraint system, when required, includes crotch
strap and must be updated at two-year intervals from date of manufacture. See General Regulations 10:5, 10:11.

•Shoulder harness mounted level with shoulders to 4” below
•Seat belt anchored at 45° angle to the floor of car
•Crotch strap to go through seat and anchor behind chest line. With OEM-type seat, crotch strap may route in front of seat.
•Seat belts anchored apart, width of driver

10:5
10:5 DRIVER RESTRAINT SYSTEMS
A quick-release driver restraint system meeting SFI Spec
16.1 or SFI Spec 16.5 is mandatory in all cars in competition required by the rules to have a roll bar or a roll cage. (Permitted in all other classes.) Driver restraint system must be clearly labeled as meeting SFI Spec 16.1 or SFI Spec 16.5 and be dated by manufacturer. SFI 16.1 or 16.5 3-inch-wide shoulder harness straps folded over and sewn to be 2 inches wide by the original manufacturer in order to fit into head and neck restraint lips/channels are acceptable. See Class Requirements for additional requirements for Top Fuel and Funny Car. SFI Spec 16.1 or 16.5 Y-type belts prohibited. (In cases where the class does not require an SFI 16.1 or 16.5 driver restraint system,
the two-year recertification does not apply.) System must be updated at two-year intervals from date of manufacture. All seat-belt and shoulder harness hardware must be originally designed to be used with each other and produced by the same manufacturer. For harness installation, see illustration. Cars using OEM or OEM-type seat may route crotch strap in front
of seat instead of through seat; otherwise, install according to manufacturer’s instructions. Mandatory that units must release all attachment points (five, six or seven, if applicable) in one action. When arm restraints are worn with a restraint system that utilizes a “latch lever,” a protective cover must be installed to prevent arm restraint from accidentally releasing the latch lever. Protective cover not required if system utilizes “duck-
bill” latch hardware. All harness sections must be mounted to the frame, crossmember, or reinforced mounting, and installed to limit driver’s body travel both upward and forward. Seat
belts may not be wrapped around lower framerails. Under
no circumstances are bolts inserted through belt webbing permitted for mounting.


10:11 SEAT BELTS
All cars not required by Class Requirements to use SFI 16.1 driver restraint systems must be equipped with an accepted quick-release-type driver seat belt. Belts must be securely fastened to the frame, crossmember, or reinforced mounting
so that all fittings are in a direct line with the direction of pull. Seat belts may not be wrapped around lower framerails. Steel castings of the type recommended by FAA or U-bolt-type mounts are permitted. If used for installation, flat steel plates must be a minimum of 1/4-inch thickness and have rounded edges to prevent cutting seat belts. Under no circumstances can belts be installed with bolts through webbing. In all cars with fiberglass floors, a crossmember (minimum 2-inch x 2-inch x .083-inch wall thickness square tubing) must be installed between framerails for proper driver’s seat-belt installation.

I started putting a mounting tube in my cars a few years ago in case somebody wants to use them. I also still put provisions for tab mounted belts. The one piece wrap around shoulder belt was a life saver for a guy like me that struggles to get everything on quickly in my roadster.

How does a wrap around shoulder belt make it easier for you?

I don’t use “wraparound” style belts with a single shoulder strap in my door car, but I don’t use bolts for the shoulder belts.

Each belt is wrapped around the roll bar a few times and then back through the harness hardware.

Because I can pull the first belt real long to hook it in, then the other end is the last one to hook so I already know where the buckle is to pull the short end up to it and latch it. I then pull my belts tight on the adjusters before a pass.

My dragster has wraparound belts, but they don’t slide easily enough to do that. I just loosen them a lot before I get out after each pass.

Gotcha, I didn't realize they would slide like that.
