Has anyone had any inspection trouble running adjustable seats in a "fast" car. I would like to bolt a set of these seat sliders under my Kirkey driver and passenger seats, and have the sliders bolted to my cross bars going from the door sill bar to the tunnel: http://www.summitracing.com/parts/SUM-G1153/
The 2012 NHRA Rule Book says the following; I believe the Section that I have highlighted in red makes this idea not legal:
The driver’s seat of any car in competition must be constructed,
braced, mounted, and upholstered to provide full back and shoulder
support. The driver’s seat must be supported on the bottom and
back by the frame or crossmember. Except as noted in SFI
Specifications, seats must be bolted with four bolts (and nuts and
washers) on the bottom and one bolt in the rear into crossbar; all
bolts must go into frame or crossbraces. Ball-lock pins for seat
attachment prohibited in all classes. All seats must be upholstered,
or as noted under Class or SFI Requirements. All front-engine,
open-bodied, supercharged or turbocharged (gasoline or methanol)
cars running 7.49 seconds and quicker must have a flameretardant-
material-upholstered seat.
Properly braced, framed, supported, and constructed seats of
aluminum, fiberglass, carbon fiber, or double-layer poly
(accessory seats) permitted. Single-layer fiberglass seats must
have steel tube framework, 1/2-inch-minimum O.D., for support.
Aftermarket aluminum seats must have reinforced head rest.
Magnesium seats prohibited.
Has anyone gotten away with anything like this? I have an idea in my head to still utilize a head rest support bar.
