Each r
oad spring and is located between the wishbone in
tegral spring seat and the body suspension turret.
Each shoc
k absorber unit is installed
co-axially within the road spring.
The lo
wer end of each shock absorber is secured to the
wishbone by a bolt which also functions as a pivot.
Adaptive damping is av
ailable as an option.
A
rear stabi
lizer bar is installed on
Supercharged and Sport Suspension models . Mounted at the rear of the wishbone
tie assembly, the stabilizer bar is connected to the wishbone by short links.
Op era
tion
As each road wheel r
i
ses, move
ment is transmitted through th e hub carrier assembly to the wishbone and axle shaft. The
corresponding rise of the wishbone compre sses the road spring and partially telescopes the shock absorber. During this
action, the spring absorbs result ing shocks and the shock absorber minimizes spring oscillation.
During cornering, vehicle weight is transferred to the outer road wheel with a resulting tendency for the inner wheel to lift.
On Supercharged and Sport Suspension vehicl es, a rear stabilizer bar assists in minimizing this tendency by transferring a
proportion of potential lift of the inner wheel to the outer wheel. This results in enhanced body stability with improved
cornering capabilities.
