This is the suspension for Alto Works.
30-way adjustable damping force and shock-body length adjustable front from Hipermax IV GT, camber adjustable pillow upper mount for the front side, shock-body length adjustable rear, and 65mm ride height adjuster increase the capacity and possibility for settings.
When testing this product in the circuit and street, the damping force for the front was tested by 6kgf, 7kgf, and 8kgf, for the rear, 6kgf, 7kgf, and 8kgf. Considering the ride quality when driving over the gap on the winding road and/or street, 6kgf for the front and 4kgf for the rear were selected; these damping force is able to derive the best performance for both circuit and street driving and take full advantage of the grip tires. With this product, the ride quality is appropriate for commuting and family leisure as well as driving on the circuit and winding road.
To enjoy circuit driving more, canceling the assist system, replacing with mild LSD, using axel collars or pillow for the front lower arm bush, etc. are recommended.
※In order to insert the adjustment dial to adjust the damping force for the rear side, drilling a 20mm hole in the interior resin panel is required.
