[Dave Steltz]

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.


So I'm still a little confused I guess...This says that for 7.49 to 9.99, I have to have a window net, a ribbon type OR a SFI 27.1 mesh-type net...and if a SFI 27.1 net is required, it must be certed every 2 years...

What am I missing ???? Is it saying that the ribbon type doesnt have to be SFI 27. and the mesh type does ?

Dazed and confused by the constant bombardment of NHRA rules makers...
