Camber Adjustment
Camber is the angle from vertical of the wheel when viewed from the front, and is said to be negative when
the wheel leans inwards at the top (positive when leaning outwards). The primary purpose of camber is to
achieve the maximum efficiency of the tyre under cornering loads and body roll, with the specification closely
allied to a particular wheel/tyre combination. The camber angle changes with suspension travel, becoming
more negative on bump, and should be measured only at the specified ride height. Incorrect camber can result
in handling deficiencies and excessive tyre wear.

Camber adjustment is effected by adding or deleting shim plates between the steering arm (to which the
upper steering swivel joint is fixed) and the hub carrier.
Steering arm
- Shimplates are available in 1mm and 3mm thicknesses.
- Reducing the shim pack thickness will increase negative camber. Adding shims will reduce negative
camber.
- A 1mm shim plate will alter camber by approximately 0.25°.
- In March '04 the caphead bolts securing the ball joint plinth to the hub carrier were upgraded from 8.8 to
10.9 grade, with a corresponding increase in torque from 45 to 68 Nm. Before fitting these bolts, inspect
the cap head for the grade marking, apply Permabond A130 (A912E7033) to the threads, and torque
tighten to the appropriate figure.
