2. FRONT SUSPENSION (DOUBLE WISHBONE)
Advantage ▶
The advantage of a double wishbone suspension is that it is fairly easy to work out the effect of
moving each joint, so the kinematics of the suspension can be tuned easily and wheel motion can
be optimized.
It is also easy to work out the loads that different parts will be subjected to which allows more
optimized lightweight parts to be designed.
They also provide increasing negative camber gain all the way to full jounce travel unlike the
MacPherson strut which provides negative camber gain only at the beginning of jounce travel and
then reverses into positive camber gain at high jounce amounts. 1.

Disadvantage ▶
The disadvantage is that it is slightly more complex than other systems like a MacPherson strut. Due to
the increased number of components within the suspension setup it takes much longer to service and is
heavier than an equivalent MacPherson design. 1.
2. Double wishbone suspension is an independent suspension design using two (occasionally parallel)
wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis
and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical
movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel
throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll
center height, scrub radius, scuff and more.

3. REAR SUSPENSION (MULTI LINK TYPE)
Multi-link (5-Link) type suspension is the independent suspension. It provides good ride comfort and
drivability by reducing the coil spring weight. Also, it increases the space for passenger compartment by
lowering the floor. This type of suspension consists of multiple links such as coil spring, shock absorber,
upper and lower arms, lateral rod and stabilizer bar.
