Soft and rigid suspension: which is better?

Fuel consumption, appearance, equipment and comfort are the main parameters that consumers pay attention to when buying a car. The suspension takes a back seat and often goes unnoticed at all. At the same time it fulfills important functions, such as ride comfort and safety on the road. Let us consider in detail the device of the suspension and its characteristics. And if the suspension along with the rest of the assemblies of the car fell into disrepair, then sell your car for scrap metal:

Which is better, rigid suspension or soft suspension – arguments on this topic are popular among motorists. The suspension is an important element of the car and performs a number of functions:

Guarantees a smooth ride;

Reduces the roll angle when entering a corner;

Reduces body oscillation when driving over potholes, bumps;

Helps keep wheel alignment sharp.

All four wheels must move up and down and be in full contact with the road surface for confident traction. Adjustment of softness and firmness will help to adjust springs, and for damping of vibrations and constant contact of the car with the road, shock absorbers are responsible.

Shock absorbers directly influence softness. Proper adjustment will allow correcting the roll and body shift when driving on a rough road. Too soft shock absorber will transform the car into rocking pendulum, and too rigid will fraught with uncomfortable ride, the driver and passengers will feel all the irregularities of the road. Defective shock absorbers influence the acceleration speed and braking distance, maneuverability and smoothness of motion. Shock absorbers should be replaced every 70 thousand km. mileage.

What is the difference between soft and hard suspension?

A rigid suspension allows the driver to keep the road situation under control and react quickly to changes in the situation. This type is often installed in sports cars. But the tight grip will affect comfort – every bump and rumble will be felt in the car.

Soft suspension provides comfort when driving on rough roads, the bumps are smoothed out, the vehicle gets a smooth ride. But when making sudden movements, such as turning or changing lanes, the car will start to lurch and lose safety.

Trust the adjustment to the professionals of the car repair shops, any change can adversely affect the performance of the vehicle and the comfort of the passengers. The slightest change in the adjustment of the rigidity of the front and rear auto suspension in relation to each other affects the control.

Before changing the factory adjustment and giving preference to rigid or soft suspension, it is recommended to get acquainted with all pros and cons arising in operation.

Rigid suspension: pros and cons. How to make the suspension stiffer?

This kind of suspension tuning gives the vehicle safety and maneuverability. Other pros:

Confident traction of the wheels with the road;

No roll when turning;

Sharp maneuvers are carried out without effort;

Braking distance is shortened;

Faster rate of acceleration;

With an abundance of pluses, there are important minuses:

Uneconomical. It wears out quickly and must be replaced every 70,000 kilometers. If necessary, it can be replaced more often.

Health Hazards. The driver and passengers will feel the road bumps and potholes, shaking can cause spine problems and back pain.

Experts give an extra argument not in favor of stiffness. At these settings one of four wheels is often unloaded. When entering a turn and other abrupt maneuvers, the car weight is redirected to one of sides and the unloaded wheel is pulled off the surface. This causes loss of control of the vehicle and provokes accidents.

There are two ways to adjust the auto suspension to a stiff level:

Adjusting springs and shock absorbers;

Installing a transverse stability stabilizer.

Soft suspension: pros and cons. How to make the suspension softer?

The main pluses were stipulated above, let’s consider the non-obvious ones:

Comfortable driving without strain on the driver’s back;

Economy (parts wear out more slowly and fail less often);

Uniform distribution of load on the wheels in a roll;

Disadvantages are related to the design of the part:

Insensitive machine control, lack of maneuverability, presence of roll and tilt during sudden movements;

The need to reduce speed before turning, without reducing the speed there is a risk of overturning the car.

There are several proven ways to make the auto suspension softer:

Buying softer tires or reducing the pressure in existing tires. The second option is not economical – driving on flat tires will force the engine to consume more gasoline and flat tires will quickly fail;

Installation of gas-oil or oil shock absorbers;

Replacing shock absorber springs. Buy new, softer ones, or trim the old ones. Trimming the old ones will lower the car.
