Front End

Wheel Alignment
Wheel alignment should be set between 0 & 2mm toe-out. Make sure that the steering shaft arm is centrally positioned when making wheel alignment adjustments.

Front Track
The standard front track is set-up with 35mm of spacing inside of each rim. Moving the front wheels in will make the kart easier to turn into the corner but the down side is it will not give as much drive out off the corner. Moving the front track by 5mm at a time is all that should be required. If you have a track that is predominately one direction and would like the kart to turn in more directly try moving only the outside front wheel in by 5mm.

The steering shaft and stub axles have several adjustments. The standard set up is the back holes on the stub and the bottom centre hole on the column. If you tend to drive very straight and do not use much opposite lock, you will find by using the two outside holes on the steering column that the kart will turn in more directly. This is due to the fact that that the inside tyre will turn at a faster rate than the outside, dragging the front of the kart quicker into the corner. The Adjustments on the stub axle will mostly change the rate at which the wheels will turn.

Rear End

Rear Track
The standard rear track is 175mm and is one of the most common ways you will change the handling of your kart. This is measured from the bearing hanger face to the hub face where the wheel bolts on. Lighter drivers will be able to move this in to 155mm if required. The closer you move the hub into the chassis the more grip you will gain. The only time this is not the case is if you have the rear hubs in too close. When they are in to far sometimes it will make the axle to stiff and not allow it to bite into the track. In this case moving the rear track out will generate more grip. You will only need to move the rear track by 5mm steps to notice a difference.

Rear Hubs
The karts are supplied with 75mm hubs. These hubs will be suitable for most drivers and tracks. If you need to loosen the rear of the kart up, you may use a 90mm rear hub at the same rear track. This stiffens the rear axle up.

Tyre Pressures
  • Front: 9psi
  • Rear: 8psi
These are the standard tyre pressures. The less grip the track has the lower the tyre pressure required. We will range between 11 & 8psi in the front and between 6 & 10 in the rear. Generally we will always run more tyre pressure in the front.

Seat Position
The standard seat position is as follows
  • Front of seat to inside front chassis rail 665mm
  • Top of seat to top of axle 300mm
  • Level with the bottom of the chassis
We will normally leave the seat position alone except if we have divers that have great hight differences. For short drivers we will lift the seat up, but normally no higher than the top of the chassis and for tall driver we will drop the seat to 10mm below the chassis. Lowering the seat will give you less side bite, and lifting the seat will give you more side bite. For 125cc karts you may move the seat further forward due to the extra weight of the engine and radiator.
