Is it necessary to install suspension stiffness adjustment?
2 Answers
Suspension stiffness adjustment is necessary to install. Suspension stiffness adjustment: Suspension stiffness adjustment refers to adjusting the comfort level of the vehicle's suspension. The suspension is the general term for all the force-transmitting connection devices between the car's frame and axle. Function of suspension stiffness adjustment: Suspension stiffness adjustment works by controlling the adjustment valve on the shock absorber through the control unit, thereby regulating the internal hydraulic circulation of the shock absorber to change its damping coefficient. Its role is to transmit forces and torques between the wheels and the frame, cushion the impact from uneven road surfaces to the frame or body, and reduce the resulting vibrations to ensure smooth driving. Suspension stiffness adjustment modes: The suspension stiffness adjustment modes are: Normal, Sport, and Comfort modes.
I don’t think adjustable suspension is a must-have, but it depends on your daily driving habits. I’ve been driving for over a decade, mainly commuting and picking up kids in the city where roads are smooth—standard suspension is enough, with minimal bumps. Adding this feature lets you switch between soft and firm settings: soft for comfort over speed bumps like sitting on a sofa, and firm for better cornering stability. The catch is the high cost, and a botched installation by a shop might mess with the car’s balance. A friend of mine tried it and had to keep going back for adjustments—annoying. If you often drive on rough roads or have family prone to motion sickness, the upgrade could be worth it; otherwise, it’s just burning money. Remember, safety first—don’t risk mods for minor comfort gains.
