For all open wheel/body cars where rear wings are permitted the wing may be fully mounted to the roll cage or frame structure only via plates and/or short brackets; maximum 6- inches center-to- center between the upper (wing tab) and lower (roll cage tab) bolts. Tube type or extended wing stands are prohibited when mounting wings to any components of the driver’s compartment of any SFI specification roll cage. Saw this on the classic FC board a short bit ago..... CLipper
