REGULATIONS AND SPECIFICATIONS FOR THE 2019 MSA REGIONAL EXTREME 4X4 CHALLENGE CHAMPIONSHIP SERIES

 

 

ELIGIBILITY OF COMPETITORS

Open to competitors holding a current MSA Competition license valid for 4x4 Challenge.

Competitors must hold a National competition license (Annual or One-event) to score points towards the National as well as Regional 4x4 Challenge Championship.   Annual or One-Event licenses must be acquired prior to the event date.

Two entries per vehicle will be accepted, as long as they consist of two separate crews in the same class.

Drivers and Co-Drivers may only compete in one vehicle on the day of the event.

Drivers must be a minimum of sixteen (16) years old and co-drivers must be a minimum of fourteen (14) years old.

 

ELIGIBILITY OF VEHICLES

The competition will be open to any lightweight 4-wheel drive vehicles for which a Code B (old code 08) driver’s licence would normally be required and qualifying to compete in the classes as defined below.

No agricultural equipment, trucks or tracked vehicles will be permitted.

The Organisers reserve the right to exclude vehicles at their discretion, deemed not suitable for this type of event or damaging to the obstacle course because of excessive     weight, size of tyres, construction of vehicle or any other reason. The decision to exclude such a vehicle will be done in consultation with the Stewards of the Meeting. Any objection against such a decision will therefore become the subject of an Appeal as to the future participation of the vehicle in question. The full entry fee for the event, from which vehicle is excluded, will be refunded to the competitor.

The following vehicle specific rules will be fixed for the duration of the 2019 season, unless safety reasons necessitate a change.

 

GENERAL CONDITIONS APPLICABLE TO ALL CLASSES

Production vehicles shall be production based 4-wheel drive vehicles of which a recognised manufacturer has manufactured fifty (50) or more of the same model.

A vehicle shall have exactly four wheels, each with exactly one tire.

Only standard tyres rated for use on the road and with a minimum speed rating of 100 kilometres per hour, will be permitted.

Paddle tyres, tyre chains, studs, double wheels, etc. may not be used.

Bead lock rims are permitted.

Tire studs, screws or any other items added to the tire are not permitted.

 

  • Where permitted, modifications to body work must be done professionally to ensure that the looks and image of the vehicle is maintained, at the discretion of the Scrutineer, who can refer it to the technical committee.
  • Only differentials from lightweight standard production vehicles (below 3500kg GVM) may be used
  • All vehicles must, in the opinion of the Organisers, be safe and capable of completing the course. Brakes and steering mechanisms will be strictly scrutineered and normal safety requirements, such as properly secured batteries, will be checked.  It is strongly advised that bucket seats be used for the competitor’s own safety.
  • A fire extinguisher, easily removable and fitted in a place easily accessible to driver, co-driver and officials, must be carried at all times. The fire extinguisher shall have a minimum capacity of 2kg and proof of purchase or service within the preceding twelve months shall be furnished. Fire extinguishers containing carbon tetrachloride shall not be used. The Chief Marshal at each obstacle will ensure that there are two (2) 1kg fire extinguishers placed at each obstacle, one at the starting gate and one at the finishing gate. In the event that a competing vehicle causes a fire that has to be extinguished with the marshal’s fire extinguisher, that competitor will have to pay the Marshal’s Association a fee of R150.00 for servicing and filling thereof per fire extinguisher. Competitors failing to comply with this ruling will not be allowed to start the next event on the calendar until this account is settled.
  • Vehicles with a passenger compartment and roof must be fitted with a roll bar. Open vehicles must be fitted with roll cages.
  • Roll bars and roll cages must be:

    Adequately mounted and positioned in such a way that the competitors are protected at all times.

    Constructed of steel tubing of minimum 32mm diameter with a minimum wall thickness of 2.5mm or 50mm diameter and higher with 2mm wall thickness. Tubes must have holes of 6mm diameter drilled into all members for checking the tube thickness.

    Mounted on the chassis, if the vehicle is fitted with a glass fibre body.

    A diagonal member or cross members, joining the main roll bar not more that 150mm from the top or bottom must be fitted.

    All welding must be of the highest quality with full penetration over the full perimeter of the tube.

    Headspace of at least 50mm shall be allowed between the outer surface of the roll cage and the top of the helmet of a competitor, when seated normally.

    Any design deviating from the specification must be presented to the Technical Committee and a ruling in writing obtained as to the safety of the vehicle, before entering an event.

  • Vehicles must be fitted with an internationally approved (FIA) safety harness. The scrutineer will inspect the expiry date on the harness. Up to five (5) years beyond their normal expiry date may be allowed. (See MSA General Circular 1/2011 for conditions.) Competitors must wear safety harnesses in all obstacles. This applies to all classes unless stipulated differently in class rules.
  • All open type vehicles or vehicles without functional side windows must have safety nets, securely fitted, covering the door or window opening from the top of the windscreen         height to the bottom of the door opening for the full width of the door. The net must not have openings of more than 70mm square and must be capable of withstanding the weight   of the competitor. Vehicles with functional windows must close the windows to 70mm below the top of the window frame if no nets are fitted. Doors must be properly secured at the discretion of the Scrutineers. A door, window or net opening in an obstacle will result in the competitor forfeiting all points for that specific obstacle.
  • All vehicles must be fitted with recovery hooks at the back and front, securely bolted down (welding is not acceptable) and easily accessible. Recovery hooks must be painted red and must accept a rope loop to be secured without requiring the use of shackles or other such attachments.
  • No loose objects will be permitted in a competing vehicle. Toolboxes, jacks, water bottles, etc. must be securely fastened or removed from the vehicle before starting an obstacle. A competitor will forfeit his/her points for an obstacle, should items deemed dangerous by the marshal fall out of the vehicle.
  • Where additional petrol tanks are fitted, the filler caps must be located on the outside of the vehicle and petrol caps must be properly sealed to avoid pollution and fire hazard.
  • It is strongly recommended that vehicles be fitted with guards over dangerous parts. The Scrutineer, in consultation with the Technical Committee, can exclude a competitor from competing if dangerous parts on his vehicle are not suitably protected.
  • Exhausts systems are unrestricted provided that they meet with the dBa limit as defined by MSA
  • Should any entrant have doubt as to the classification of his vehicle, he must obtain a ruling in writing from the Technical Committee before entering an event.
  • All vehicles must have some form of protection between the engine and the driver’s compartment(fire wall), suitable and sufficient in the case of:

    fire for preventing the passage of flame,

    rotating engine and driveline components,

    as well as hot or pressured fluids.

  • All vehicles participating in the 4x4 Challenge Series must have an audible warning system fitted that will allow the driver to warn bystanders. This can be either a horn or a reverse alarm.
  • Brakes may be upgraded but independent brakes will only be allowed in the classes as defined in class rules.
