The low mount multi link suspension has been 
adopted.
There are the following features.

.

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.

• Cornering performance has been optimized by 

selecting the stabilizer diameter.

.

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 and the Eibach coil 

spring

*

 have been established.<GSR: optional 

equipment, MR: standard equipment>
NOTE: 

*

: The Eibach coil spring has widely been 

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

.

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.
