CR14: DEFLECTOR PLATE
All rear-engined vehicles must have a deflector plate to protect the driver from the engine. Plates must extend from top blower pulley to bottom pulley and be at least 25mm wider than each pulley for supercharged cars, whilst others must have plate covering from shoulder height to bottom of chassis. Minimum attachment for any plate is four 10mm high tensile bolts.
CR15: DELAY BOXES
Any electrical, pneumatic, mechanical or other device attached to existing components that intentionally creates a delay between the driver releasing the clutch, trans brake, etc., and the forward movement of the vehicle will be considered a delay device and is prohibited.
CR16: DRIVELINES
16.1	On any car where the driver sits over or behind the engine, a suitable protective shield of 3mm minimum thickness steel plate must be installed over these units with universal joints securely mounted to the rear and centre section and the gearbox tail housing. Couplings are highly recommended in place of U-joints wherever possible. For those units with straight couplings, the minimum requirement is 2mm thickness aluminium which must contain an inspection cover for the removal and inspection of the coupling and must be securely mounted or as noted in the Class Requirements.
16.2	In place of a cross member in the immediate vicinity of the front universal joint, all competition cars using open drive shafts must have a 360° retainer loop of 6mm thickness and 50mm width securely mounted and located within 150mm of the front and rear universal joints to support the drive shaft in the event of a U-joint failure. Open drivelines passing any part of the driver's body must be completely enclosed in a 3mm thickness steel plate securely mounted to the frame or frame structure. All cars using open Hotchkiss-type drivelines must have radius arms, traction bars, or some suitable pinion support to prevent rear end housing rotation. It is highly recommended that a torque tube be used to enclose all drivelines.
CR17: DRIVELINE ANTI-ROTATION DEVICE
An anti-rotation device is required in any vehicle where the driver sits over or behind the rear-end (differential).
CR18: DRIVER'S COMPARTMENT
All interior panels (firewalls, floors, wheel tubs, doors, etc.) within the driver's compartment of enclosed-cockpit vehicles where the driver is located behind the engine must be constructed of materials other than magnesium.
