Features

•  Double angular ball bearings which integrated the wheel hub and the wheel bearing have been adopted for the front and rear axles.
•  An aluminum front knuckle and rear knuckle have been adopted, and unsprung weight has been reduced.
•  An aluminum differential carrier and differential rear cover have been adopted, reducing rear differential weight.
•  A super-LSD has been adopted (limited slip differential (LSD) vehicles).
•  The following parts have been adopted to reduce vibration and noise:
―  Bell-shaped constant velocity joint has been adopted for the wheel-side joint of the rear drive shaft.
―  A tripod-shaped constant velocity joint has been adopted for the differential-side joint of the rear drive shaft.
