If your car’s wheels point inwards slightly when looking from above then they are said to have ‘toe-in’. If the opposite is true and they point outwards, then ‘toe-out’ is present. If they sit parallel then they are at ‘neutral toe’. Most cars R/C cars will be set to have neutral toe or toe-in. With the correct toe angle on the front you will have a stable car that generates good front-end grip, and by setting the correct toe angle on the rear, this will give good rear end traction through corners and aid straight-line stability off road.
You can adjust the front toe angle simple using the steering links. By shortening the links you create more toe-out, and by doing the opposite and lengthening the links, you can set the wheels to have neutral toe or toe-out. The rear angle is altered in different ways dependant upon the make and model of car you own. Almost all adjust the rear lower wishbone to give desired angle, and simply swapping rear toe-in blocks can achieve this, or by adjusting rear toe may be set by changing the uprights or hubs, and some even offer adjustment by turnbuckle link arms.
