Details
The active retainer makes the upper and lower spring seat surfaces movable with pillow balls, so that the spring seat surface is maintained horizontally regardless of the movement of the torsion beam. A proper rate is generated and the torsion beam moves linearly with respect to the road surface. This effect not only improves the feeling of contact with the rear when cornering, but also allows the rear to follow the movement of the front, so you can step on the accelerator more quickly and the start-up speed is greatly improved.
