Rear-End Setup:
How to Add more Rear-End Grip
1. Narrow the width of the rear hubs on the axle
2. Use optional seat stay from seat mounted to the bearing carrier on the axle
3. Lower the rear axle (raise the chassis) – not highly recommended only in extreme conditions
Conditions to add Rear-End Grip:
On a green track, or in damp / wet weather conditions
If you need to increase rear end traction
If front end is too reactive and the rear end is stepping out
How to Remove Rear-End Grip:
1. Widen to width of the rear hubs on the axle to the max. permitted length at 140cm
2. Raise the rear axle (lower the chassis) – not highly recommended only in extreme conditions
Recommended Seat Position:
Factory Recommendation for a driver sizes 5ft 6” – 6ft:
From Front Chassis Rail to Front Of Seat RHS: 63cm
From Rear Axle to Crown of the Seat: 20cm
It is possible to alter this seat position for a very small or larger driver so the seating position is more
comfortable. The max range recommended is from:
From Front Chassis Rail to Front Of Seat RHS: 58-66cm
Tyres Pressures:
Maxxis Sport T4 Slicks:
This tyre is a medium compound which is extremely durable. The recommended window for this
tyre is from 12Psi – 18Psi. The occasion to run lower tyre pressures would be in very hot track
conditions or for a very long race so the tyre will not drop off a lot during the race.
The time to run higher pressures will be in cold conditions or in damp weather so it is necessary to
generate as much tyre heat as fast as possible so the tyre will work.
Maxxis Sport T4 Wets:
The wet tyre is a soft rain tyre so care needs to be taken so not to overheat the tyre from new. The
recommended window can range from 10Psi – 20Psi depending on how wet the track is and also
how abrasive the surface of the track is. Here is a typical recommended guide for setting the tyre
pressures in wet conditions:
