ALTEZZA Height Adjustable Suspension for Racing (Exclusively designed for competition)

■Car height and damper force can be adjusted freely
By enabling the car height and damper force to be varied to match driving conditions and driver preferences, the vehicle's steering characteristics, center of gravity, cornering weight, and more can be easily adjusted.
■Preload and vehicle height adjustment types
Enabling the spring preload and car height to be adjusted individually allows you to adjust the car height without changing the suspension stroke, enabling you to maximize Altezza's potential for each individual circuit.
■Selectable spring rate
We have springs ranging from K= 98.0 Ns (10 kgf/mm)/mm to 235.2 Ns (24 kgf/mm)/mm. This means that you can select the optimal spring rate according to driving conditions and preference.
