As usual someone is on the ball with changes. Some of us have already run two divisional races and purchased new stuff. Oh well it looks so much better than the perfectly good one it replaced

NHRA has changed its thoughts on the window net rule for cars slower than 7.49 (4.50). The section in RED has been REMOVED and replaced by the section in BLUE.

SECTION 20: GENERAL REGULATIONS, INTERIOR: 6, WINDOW NET (Page 29) (3/5/2012) An SFI 27.1 ribbon-type or mesh-type window net is mandatory on any full-bodied car required by the rules to have a roll cage. An SFI 27.1 ribbon-type or mesh-type window net is mandatory on any full-bodied car running 7.49 (*4.49) or quicker. For full-bodied cars running 7.50 (*4.50) to 9.99 (*6.39) or if vehicle runs 135 mph or faster a ribbon-type or SFI 27.1 mesh-type window net is mandatory unless otherwise specified by class requirements. SFI 27.1 window net, when required, must be updated at two-year intervals from the date of manufacture. Window net must be securely mounted on the inside of the roll cage, with the permanent attachment at the bottom. All attachment points must be designed in an attempt to protect the driver and avoid contact with track surface or guardwall. Eyelet clips, dogleash hardware, hose clamps, etc. prohibited. Penetration of webbing, except as performed by manufacturer, prohibited. Any modification to net must be performed by manufacturer.

NHRA members can find this information in the "Rulebook amendments" section on the www.nhraracer.com site.

This change means the SFI ribbon style nets are not needed until you run faster than 7.49. So you don't need to be changing your ribbon net every 2 years, unless you have a mesh style net, or run faster than 7.49 (4.50)

I don't know what your talking about. Your last sentence about not changing a ribbon net every 2 yrs contradicts what the rules says. I've read it 3 times. If you run between 7.50 and 9.99 with a ribbon net you have to change it every 2 yrs.

No it says if you run between 7.50 and 9.99 you have to run a Ribbon net or a SFI 27.1 mesh net. then it goes on to say all the SFI nets have to be re-certed every 2 years. It does not say the ribbon ones for 7.50 to 9.99 have to
