Camber Adjustment
Camber is the angle from vertical of the wheel when viewed from the rear, 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 shim plates are fitted between the top wishbone ball joint plinth and the hub carrier.
- Shims are available in 1 mm thickness. Note that on the left hand side, the shimplate fitted against the hub
carrier must always incorporate the mounting bracket for the wheel speed sensor harness connector.
- Reducing the shim pack thickness will increase negative camber. Adding shims will reduce negative
camber.
- A 1mm shim plate will alter camber by approximately 0.3°.
- 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.
