harness rules for street prepared
I have been looking over the rules regarding harness requirements and was wondering if my stock Schroth 4 point harness which uses 2" straps would be acceptable with the addition of an anti-submarine 5th strap which the buckle has the ability to acept as an option.Thanks.Mark

I am not sue which class I would be required to run in,and after reading the class requirements,I'm still not sure.
The car does not have a conventional windshield,so I was assuming I would be placed in a prepared class.
It seems to fit in the street prepared B class as it is a 4cyl. supercharged motor with all factory running gear and is street legal and registered.I'm just not sure about the windshield issue.Photo:

The SCCA allows 2" lap belts if a six point & FIA Cert - page 74 of the GCR so I assume that we would allow it as well.
Lap Belts
B. A six or seven point system, recommended for use in all automobiles, consists of a three (3) inch seat belt or an FIA approved two (2) inch seat belt (SFI 2-inch seat belts are not currently allowed), approximately a three (3) inch strap over the shoulder type of shoulder harness, and two approximately two (2) inch leg or anti submarine straps. The seven-point system also has an approximately two (2) inch anti-submarine strap.
C. The material of all
Sholder Harness
Harness Threading: Assemble in accordance with manufacturers instructions.
J. FIA certified 2-inch shoulder harnesses are allowed when the HANS® device is used by the driver. SFI 2-inch shoulder harnesses are not currently allowed. Should the driver, at anytime not utilize the HANS® device, then 3-inch shoulder harnesses are required. The replacement cycle for the 2-inch harnesses shall be per Section

I agree with Bill and Don. Sounds like a good reason to submit a rule change.
With a 5+ point harness, we should allow 2" lap belts. I would also go along with 2" shoulder harnesses, especially if a HANS is used.
I think we should specify the certification required (SFI, FIA), and let the competitor decide which configuration works best for them. This may cause a nasty reaction from some, but we should also verify certification/dates. i would much rather have a participant in a new 2" harness than a 10 year-old 3" harness!
