Vehicle Classes - the reasoning behind them

A Winch Challenge in concept is for production based 4wd vehicles. The events are to test all manner of general 4wd skills. With that in mind the rules should cater for all types of 4wds and ones that have been modified with all manner of competition in mind. Trials, off-road racing and team events all have differing specific requirements but a Winch Challenge crosses over into all of these sports.

The goal is safe, fair and consistent racing. Safety is paramount so all changes to rules at the bare minimum maintain the current safety or improve upon it. All sanctioned events should have the same rules so that competitors know basically what the event is, that they will be able to race, that the rules are the same and they will be racing against guys at a similar level.

The plan is to change the vehicle specification rules to provide for four classes. There is no requirement for any event to have all or any of the classes. That will be the sole discretion of the event organisers.

The new vehicle specs have been written to encourage people into the sport and then provide a logical pathway for them to progress through to a higher level if they choose. If they don’t want to progress then they can stay at any level they want as long as the vehicle complies. Also as long as you comply with the safety requirements, then you can compete in any class as long as you don’t exceed the modification limits.


Standard Class

This is for your basic club truck with minimal mods. 4 point rollbars only are required. No WOF required but extra mods are possible if road legal. This is for the experienced club member who likes the idea but doesn’t want to do specific mods just to compete in an event.

Club Class

This is the next level with more mods and is probably for someone who is aiming higher but is learning the sport as they go. The modifications are limited by either Challenge or Super Modified specification with points for each modification. At the current limits you would be able to do 12 performance modifications. No WOF required. This is really for the very well setup tough truck or someone who has already had plenty of hard yakka experience.

Challenge Class

This is the traditional winch challenge truck. Road legal production based with rules to keep factory type vehicle. This is what has traditionally been a Winch Challenge truck.

Super Modified Class

Pretty much if you can do it road legal then you can do it here. Basically production based vehicle, must look like a Challenge truck but far less rules. The rules around chassis and body modification are more relaxed and while no WOF required all mods must be to WOF or LVVTA standard.


So what you end up with is an entry level class that is easy for people to have a go in. Minimal safety requirements but the tracks MUST be set to minimise the chances of rollover and high speed must be eliminated. This is the level we would assume most local club competitions would be at. At the local level it could be run without a rollbar as long as the tracks are set accordingly.

You can then progress into the Club Class and get exposure to high speed and the steeper tougher courses. This is where you really learn the sport.
From Club you would progress to either Challenge Class or Super Modified Class depending on level of modification and whether you have a road legal truck or not.

Club, Challenge and Super Modified would be able to compete at the same time on the same tracks. Maybe there would be some tracks that Club would go through first or the tougher sections bypassed. The safety is the same, so the only difference would be the speed they compete at.

To limit modification in the Standard and Club Classes but still allow the variety we are used to, we have proposed a points system. This allocates point per performance modification and then there are a limits set for the two classes. In some cases, factory specification will be allocated points e.g. factory diff locks and PTO winches. The goal is to provide a level playing field. It is not to tell people what they can and can’t do.
