Can the suspension be adjusted to be softer?

Suspension can be adjusted to be softer, but it is a relatively professional task. Each vehicle model is set to a fixed and optimal hardness from the factory, and it is best not to adjust it unless for modification purposes. Suspension stiffness adjustment is achieved by controlling the adjustment valve on the shock absorber through the control unit, thereby regulating the internal hydraulic circulation of the shock absorber to alter its damping coefficient. The primary purpose is to balance and switch between vehicle handling and comfort. It is important to note that adjusting the stiffness of the chassis suspension is distinctly different from adjusting its height. Height adjustment, typically seen in air suspension systems, involves balancing between improving vehicle ground clearance for off-road capability and lowering the center of gravity for better handling. Suspension stiffness adjustment is used to modify the comfort level of the vehicle's suspension, typically offering three modes: Normal, Sport, and Comfort. These modes cater to different driver needs at various levels, allowing the driver to switch between modes via a simple control switch to adapt to different road conditions, making the operation relatively convenient.
As a veteran driver with over 20 years of experience, I believe softening the suspension is fine, especially with some new cars featuring electronic suspension control. Like my SUV, it allows adjusting the stiffness via the central control computer. Softening essentially makes the shock absorbers less rigid, resulting in a smoother and more comfortable driving experience with reduced vibrations when going over speed bumps. However, not all cars support this—it depends on the original configuration. High-end cars often support adjustable suspension, while regular cars might require modifications like replacing shock absorbers or installing softer springs. Getting it adjusted professionally with instruments can cost anywhere from a few hundred to several thousand. After softening, the ride becomes much more comfortable, but you may notice more body sway during high-speed turns or on bumpy roads, so balancing comfort and safety is crucial. I spent a few months testing and adjusting parameters to find the right setting. Some cars even have active suspension that automatically adjusts stiffness based on road conditions—pretty smart.
