IMPROVEMENT IN SUSPENSION 
RIGIDITY

• Based on the highly rigid full-flat crossmember, 

by adding the reinforcement part such as a stay, 
the respective rigidity of the crossmember has 
been improved significantly.

• The forged knuckle has been adopted. The defor-

mation of knuckle by ground contact force has 
been suppressed, and the camber rigidity and lat-
eral rigid brake caliper supporting rigidity have 
been improved.

.

IMPROVEMENT IN CORNERING 
PERFORMANCE

• The 18-inch low-aspect ratio tire has been 

equipped, the wheel tread has been widened, 
and the suspension rigidity has been improved, 
for better cornering performance and cornering 
limit.

• By adopting the 18-inch low-aspect ratio tire, the 

caster trail amount has been increased, resulting 
in the better steering feel and steering response 
for slight steering operation.

• The caster angle has been increased and the 

camber angle to the ground while operating the 
steering wheel has become negative, for better 
cornering performance within the middle and 
large steering angle range.

• By widening the stabilizer diameter, the optimal 

roll posture for cornering limit improvement has 
been secured.

.

IMPROVEMENT IN QUALITY

• The compact lower arm pillow ball bush has 

newly been designed. The stroke feeling by the 
pillow has been improved, the rubber damping 
characteristics has been tuned, and the vibration 
from the ground has been reduced, for improved 
quality.

• The Bilstein shock absorber and the Eibach coil 

spring

*

 have been established as options.

NOTE: 

*

: The Eibach coil spring has widely been 

adopted in the motor sport field; sports vehicles in 
Europe, F1, WRC, etc.

.

WEIGHT SAVING

• To respond the increase of weight and ground 

surface force by adopting the 18-inch low-aspect 
ratio tire, the suspension structure has been opti-
mized, resulting in weight saving.

• By adopting the Bilstein shock absorber, the 

outer cylinder thickness has been reduced, 
resulting in weight saving.

.

IMPROVEMENTS IN RELIABILITY

• The deep groove upper bearing, which support 

the vehicle weight to the strut upper insulator, has 
been enlarged and sealed for the better reliability.

• The upper part of the coil spring has been 

squeezed, making the big-tail shape. Conse-
quently though the vehicle weight is increased 
and the spring constant is high, the gap between 
coils can be widened, reducing the rattle noise 
and scratches.

.

HEXAVALENT CHROMIUM-FREE 
COMPONENT

• Hexavalent chromium has been eliminated from 

bolts and nuts.

.

LEAD-FREE COMPONENT

• The lead-free grease has been adopted for the 

ball joint.

REAR SUSPENSION

The low mount multi link suspension has been 
adopted.

IMPROVEMENT IN SUSPENSION 
POSITIONING RIGIDITY

• The arm layout has been optimized. (Each arm 

support span has been widened.)

• The rigidity of the arm installation part has been 

improved. (Better rigidity of crossmember, addi-
tion of trailing arm bracket)

.

IMPROVEMENT IN CORNERING 
PERFORMANCE

• The 18-inch low-aspect ratio tire has been 

equipped, the wheel tread has been widened, 
and the suspension rigidity has been improved, 
for better cornering performance and cornering 
limit.

• By adopting the non-linear coil spring, the suffi-

cient wheel stroke has been secured, and the 
cornering stability not affected by the road condi-
tion has been obtained.

• By widening the stabilizer diameter, the optimal 

roll posture for cornering limit improvement has 
been secured.

.

IMPROVEMENT IN STROKE FEELING

• The numbers of pillow ball bush and ball joint on 

the arm installation part have been increased for 
the better road-holding quality of the suspension.

.

IMPROVEMENT IN DAMPING FEELING

• The shock absorber, which is arranged on the 

same axle for the coil spring, has been mounted 
with a knuckle for better absorber efficiency.

• The shock absorber installation angle has been 

optimized.

.

IMPROVEMENT IN QUALITY

• The Bilstein shock absorber has been estab-

lished. <GSR: optional equipment, MR: standard 
equipment>

.

IMPROVEMENT IN ALIGNMENT 
ACCURACY

• Arms have been installed to the lattice cross-

member, and the rear suspension has been bro-
ken down into sub assembly for the better 
alignment accuracy.

.

WEIGHT SAVING

• The aluminum forged upper arm, trailing arm, 

and control link have been adopted for weight 
reduction and high rigidity.

• The light weight lower arm made with a steel pipe 

has been employed.

.

HEXAVALENT CHROMIUM-FREE 
COMPONENT

• Hexavalent chromium has been eliminated from 

bolts and nuts.

.

LEAD-FREE COMPONENT

• The lead-free grease has been adopted for the 

ball joint.
