Rear Suspension

GENERAL INFORMATION

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, addition 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 sufficient wheel stroke has been secured, and the cornering stability not affected by the road condition 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 crossmember, and the rear suspension has been broken 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.
