SECTION 11 GENERAL REGS, BODY:7,7:1 AIR FOILS, WINGS (PAGE 69)
Thats it---no changes, as was explained to me (this is a saftey committee ruleing and not the chassie committee) unless a SFI spec is written on the way the struts are mounted to the back of the car. That will not happen because even with a over-kill spec things can still happen and the racer will look for sombody to blame.
Its a grey area BUT---- If one were to make the struts a permanet welded fixture to the cage and not bolt on, one could argue that it is an extention of the roll cage and that constuction exceeds the MINIMUM specs for the cage itself since it is not removable. The thing that they are trying to get rid of is the bolt-on mounting method , because without a spec people are using too small of bolts-tabs(single shear)-heims and the tubing itself.
