However it appears to me that there are no exceptions, this is from the 2019 rule book.

"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."
