SUSPENSION
The suspension which has been adjusted to new
body dimension with the optimal tuning has im-
proved its cornering ability.
A McPherson strut-type suspension has been used
at the front, and a multi-link suspension has been
used at the rear.
FEATURES
High Steering
Stability
1. Suspension geometry optimized by linearisation of toe change, etc.
2. Wider tread
3. Optimized the roll center height
4. Increased the suspension stroke of the compressed side
5. Increased the lateral rigidity equipped with crossmember bars and flatted
crossmember
6. Damping forces of front struts and rear shock absorbers as well as
their coil springs’ characteristics optimized
7. Optimized suspension bushings
Enhanced Riding
Comfort
1. Increased the suspension stroke of the compressed side
2. Damping forces of front struts and rear shock absorbers as well as
their coil springs’ characteristics optimized
3. Spring characteristics of bump rubber optimized
4. Characteristics of suspension bushings optimized
Reduced road
noise
1. Increased the volume of stabilizer bushings
2. Adoption of two mounting bolts to the stabilizer bracket
FRONT SUSPENSION
FEATURES
A McPherson strut independent suspension-type
suspension has been adopted as the front
suspension.
It has improved its limitation of
capacity as well as securing the sufficient lateral
rigidity and rolling rigidity as a high performance
vehicle.
D
With widened tread and optimized roll center
height, the cornering performance from initial
responce to limited performance has been
improved.
D
Adopted the two-stage selectable structuare
of camber angle according to driving mode like
EVOLUTION-VI.
D
Stabilized the vehicle behavior during cornering
by lowering the installation position of the
steering gear box with linear toe change.
D
Increased the horizontal strength, improved the
steering feeling and the rigidness at the time
of cornering by making the cross member flat
and connecting two reinforced bars
(crossmember bar) at the installation part of
the both right and left lower arms.
D
Improved the cornering limitation with improved
adhesion at the time of rolling by increasing
bump strokes.
D
Achieved the weight reduction being equipped
with aluminium lower arm like EVOLUTION-VI.
D
Improved reliability by making the size of
mounting bolts larger at the front and rear
bushing installation parts of lower arm.
D
Improved the stroke feeling by replacing the
rear bushings of the lower arm with the pillow
ball bushing with rubber.
D
Restricted the useless movement of lower arm
equipped with stopper rubber at the front and
rear bushing mounting parts of the lower arm.
D
Improved the reliability and steering feeling by
reducing friction as well as making the ball size
of lower arm ball joint larger.
D
Improved the camber rigidity by adopting an
inverted strut like EVOLUTION-VI.
D
Improved the steering stability by optimizing
the damping force of shock absorbers and
spring constants of coil springs.
D
Adopted a strut insulaor with previous results
like EVOLUTION-VI.
D
Prevented the occurance of unusual noise by
increasing the volume of stabilizer bushing.
D
Prevented the occurance of unusual noise
caused by lateral sliding of brackets with
installation of two mounting bolts to the
stabilizer bracket.
