Toe is the angle of the wheels when looked at from above the car. Toe is used to stabilize
the car at the expense of traction, as it introduces friction and therefore some slip in the
tires.
• When the wheels are parallel with the centerline of the car, toe is 0° (neutral).
• When the wheels are closed towards the front, this is called toe-in (positive value).
• When the wheels are open towards the front, this is called toe-out (negative value).
Front wheels can have either toe-in or toe-out.
Rear wheels should always have toe-in; they should never have toe-out.
Toe may be adjustable at either end of a suspension arm:
• Inboard toe (if available) is typically adjusted by altering the angle of the suspension
arm’s inner pivot pin. Inboard toe adjustment is not available on all vehicles.
• Outboard toe (if available) may be adjusted in two ways: at the front by adjusting the
lengths of the steering rods; at the rear by altering the angle of the suspension arms
inner mounting pin (or other method)
EFFECTS OF TOE ADJUSTMENT
FRONT TOE
Increasing (more toe-in)
• Makes car easier to drive
Decreasing
(less toe-in, or more
toe-out)
• Decreases understeer
• Increases steering at corner entry
• Faster steering response
• Less stable under acceleration
• Makes car more diffi cult to drive
REAR TOE
Increasing (more toe-in)
• Increases understeer
• More stable exiting on-power at corner exit and braking
• Less chance of losing rear traction
• Decreases top speed
Decreasing (less toe-in)
• Less stable at on-power corner exit and braking
• More chance of losing rear traction
• Increases top speed
MEASURING TOE
INITIAL STEPS
SET-UP COMPONENTS:
Prepare the car as follows:
Use the following set-up components:
• Shocks: Attach all shocks
• Wheels: Remove all wheels
• Flat Set-up Board #108202
• Assembled Set-up Stands #108805
• Toe Gauge (for Truggy #108841)
• Droop Gauge Support Blocks #107703
When using the acrylic toe gauge, the toe gauge does not fi t over the pins on the set-up
stands so that the toe gauge is in one position. The toe gauge is designed to slide over
the pins from one side to the other, depending on which wheel you are measuring (left or
right). Follow the instructions carefully.
