CR79: VENT TUBES / BREATHERS
Mandatory on all Top Eliminator vehicles and accepted in all other classes. Where used, the tubes must terminate into an acceptable, permanently attached catch-tank with a capacity of four litres per engine. The catch-tank must be able to keep over-flow off the track and a sight glass or tube is recommended to verity that tank is empty prior to each run.
CR80: WEIGHT
80.1	All weights are applicable after a vehicle has completed a run and must include driver.
80.2	MSA is currently evaluating cars/vehicles and performance and will create certain minimum weight requirements, for specific engine, car and drivetrain combinations to compensate for increasing performance and maintaining of safety standards. (MSA circular to follow).
CR81: WEIGHT DISTRIBUTION
Each vehicle must have an adequate percentage of its weight carried on the front wheels to ensure proper handling ability at all times. Additional front-end weight will be required by the scrutineer on vehicles experiencing excessive wheel stands or carrying the front wheels during acceleration.
CR82: WHEELBASE
Minimum wheelbase is 2.30 metres, unless the vehicle has original engine. Maximum wheelbase variation from left to right is 50mm.
CR83: WHEEL WELLS
See Class Requirements.
CR84: WHEELS
84.1	All hubcaps must be removed. Scrutineers must check for loose lugs, cracked wheels, worn or oversize lug holds, spindles, axle nuts, cotter pins, etc. Snap-on hubcaps are not permitted on any class of vehicle during competition. Stock mag wheels may use lug nuts as supplied from the factory.
84.2	Each vehicle must be equipped with automotive-type wheels with a minimum diameter of 1325mm unless class regulations state otherwise. Rim width for enclosed, i.e. Sedan, bakkie, Coupe, etc. vehicles must be a minimum of 75mm.
84.3	Motorcycle rims or lightweight automotive wire wheels acceptable on front of Dragster only, provided total weight of vehicle does not exceed 900kg including the driver. Each wire rim must be equipped with 3mm minimum diameter steel spokes properly cross-laced to provided maximum strength. All available spoke holes in rim and hub must be laced, and omissions to lighten wheels are not permitted.
84.4	Where it can be established that a "beam breaker" shield is required on wire rims, it is mandatory for a competitor to securely and permanently fit a device to clearly cut the startline staging beams before entering a competition.
84.5	Maximum rim width on any vehicle is 406mm.
84.6	No rear wheel discs or covers permitted in any category and the use of sports car or automotive wire wheels is restricted to vehicles to which they were originally fitted.
84.7	Either steel or good condition rubber valve stem caps are required on all wheels.
CR85: WHEEL STUDS
A wheel stud must protrude from the outer face of the wheel by a distance at least equal to the diameter of the stud. Scrutineers are required to check the fit by removing at least one lug nut on each rim if it is not readily recognisable that the stud extends through the rim far enough.
CR86: WHEELIE BARS
Wheelie bars are permitted as per class regulations. Wheels must be non-metallic.
CR87: WINDOW NETS
85.1	All enclosed vehicles with doors, i.e. Sedans, Bakkies, Coupes, etc.) requiring the use of a "roll cage" (i.e. those capable of 10.50 or quicker) must be fitted with a driver-side ribbon-type window net with minimum dimensions of 450mm x 600mm or alternatively properly adjusted arm restraints.
85.2	Net must be attached to the inside of the roll cage top bar and also to the intrusion bar. The net must be permanently attached at the bottom either by hose clamping to the intrusion bar or some other acceptable method whilst the top must be clipped at each end to eyebolts or a seat belt-type fastener. Chief startline Marshall must ensure competitors have net or restrains correctly fastened before going into stage. Rubber shock cords are not acceptable for mounting net.
CR88: WINDSCREENS AND WINDOWS
86.1	On open bodied vehicles, a metal, plastic or plexiglass deflector must be installed to divert wind, liquids, foreign matter, etc., over the driver's helmet. The wind deflector must be securely mounted and installed in such a manner that it does not in any way obstruct the driver's frontal view.
86.2	Windshields, when called for in class requirements, must be safety glass, plexiglass or other shatterproof material. The front screen must be clear, without tinting or colouring except factory-tinted safety glass.
86.3	Tinting of side windows cannot be such as to prevent visibility of driver through side windows at night events. Where Funny Cars have full side windows fitted, a 150mm diameter opening must be provided to facilitate access from the outside.
