Toe-in
>
Turning the tensioning screw counter-clockwise (to the rear) lengthens the track
rod, and the rear of the wheels is pressed outward.
Toe-in during travel brings about better directional control of the tyre and more
direct response to steering. Driving with toe-in makes the inner sides of the tyres
wear faster.
Toe-out
>
Turning the tensioning screw clockwise (to the front) shortens the track rod, and
the rear of the wheels is pressed inward.
Adjusting with toe-out brings about a softer response to steering.
Driving with toe-out makes the outer sides of the tyres wear faster.
. Adjusting the camber
The wheels are attached between the upper and lower wishbones. Changing the length of the top wishbone
brings about a change in the incline of the plane of the wheel.
The wheel camber is the incline of the plane of the wheel with regard to the vertical plane.
When the top edges of the wheels on one axle are inclined inwards (toward the middle of the vehicle), this
is called negative camber. Eine nach aussen geneigte, V-förmige Stellung der Räder wird als positiver Sturz
bezeichnet.
Negative camber on the front axle increases the directional control forces of the wheels when cornering --
the steering responds more directly. The steering forces become less, and the handling smoother. At the same time the axial
bearing play is eliminated, because the wheel is pressed toward the axle onto the
steering knuckle.
Negative camber on the rear axle reduces the tendency of the rear of the vehicle to
swerve out in curves.
Adjusting with negative camber causes the contact surface of the tyre to shift
inward, increasing wear on the inner side of the tyre.
Adjusting the camber on the front and rear axles
The camber is adjusted using the tensioning screws (arrows) in the top wishbones.
>
Turning the tensioning screw clockwise (to the front) shortens the wishbone, and
the wheel is drawn inward at the top toward negative camber.
>
Turning the tensioning screw counter-clockwise (to the rear) lengthens the wish-
bone, and the wheel is pressed outward at the top toward positive camber.
. Readjusting the rear spoiler
Besides the set up of the chassis, the handling can also be influenced by readjusting
the rear spoiler.
Setting the rear spoiler at a steep angle provides for downthrust and thus for grea-
ter attraction on the rear axle at low speeds, and a more level position provides for
downthrust at higher speeds.
The angle of the rear spoiler can be set to be more steep or more level by and doing
the mounting device and readjusting it in a different fastening point.
