NHRA harness spec?

[Nadine UK GTS]

Did a search but couldn't find anything on the approved point harness spec.

What is the requirement for a below 12 second quarter mile car (besides 3" straps) I am wondering if it could be a 3-point type, or does it have to be a 4-point or 5-point?

As per the 2003 rule book:

"Driver: 10


Driver restraint system
Seat belt is mandatory in all cars. Three-inch driver restraint system meeting SFI Spec 16.1 mandatory in any car 11.99 (*7.49) or quicker, in convertibles running 13.99 (*8.59) 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"

I am trying to find the sections 10:5 and 10:11 on line for you. It is too much for me to type using only two fingers.

Sorry but the 2003 Rule Book is not available on line.

We need to find out exactly what the SFI Spec 16.1 is.

It does make a mention of how many points the harness must be. All the book says is "A quick release, 3 inch ......harness......meeting SFI Spec 16.1...."

Maybe Tom @ BTR will see this and give you a better answer.

Thanks Jerome, I didn't know about the 2 year update rule (I had heard they deteriorate if the sun gets to them). Yes, Tom would be the guy to advise re 4 or 5 point system. Thanks. I'm in favor of a camlock 4 point (with crutch strap) but, where the 2 shoulder straps go into one "Y" piece.
