Suspension (04.00)
Front Suspension (04.01)
Description
Suspension Arms
The upper suspension arm is attached to the body structure.
The lower suspension arm is attached to the front subframe.
Each upper suspension arm has a press-fit ball-joint, and two
interleaved rubber bushes. Two bolts attach the upper
suspension arm to the body structure.
Each lower suspension arm has a press fit ball-joint and
metal-to-rubber bonded bushes which are attached to the
front subframe by two eccentric cam bolts (Camber and
castor settings).
Anti-roll Bar
The anti-roll bar, is attached to the subframe in two positions
by rubber bushes and clamps. The outer ends of the anti-roll
bar are attached to the lower suspension arms by drop links.
The anti-roll bar provides the required stiffness to control
body roll.
Vertical link
The Vertical link (Knuckle Joint) swivels on the upper and
lower suspension arms via ball-joints, and carries the hub, a
unit 3 wheel bearing (including the ABS encoder ring), the
wheel speed sensor, the brake caliper, and the brake disc
and shield. The position of the Vertical link is determined by
the movement of the steering rack, which is connected to
the Vertical link by the steering track rod.

Suspension (04.00)
Rear Suspension (04.02)
Description
Anti-roll Bar
An anti-roll bar, mounted on the rear subframe connects to
the LH and RH lower suspension arms via drop links. The
drop links, with a ball joint at either end, transmit vertical
movement of the rear suspension to the anti-roll bar,
minimising body roll.
Vertical Link
The vertical link carries the hub, the cartridge wheel bearing,
the ABS rotor, the wheel speed sensor, the brake caliper, the
hand brake caliper and the brake disc and shield.
A toe control (track-rod) arm secures the rear of the vertical
link to the subframe. The toe control arm is adjustable, on
an eccentric cam, to alter the rear road wheel toe alignment.
