In this article, you find out how to identify good suspension


Good suspension should provide independent shock absorption to individual wheels. That means, when one wheel rides over a hump, the shock will not be transferred to other wheels. 



Good suspension should have adequate body roll. Excessive body roll leads to too much weight transfer, influencing the steering response. Restricting body roll to minimal may create an uncomfortable driving experience because of excessive Gforce. Moreover, body roll could provide information to the driver, telling him or her the state of cornering and whether the car has reached its limit. Complete elimination of body roll is not optimal. 



Good suspension should have good geometry, such that wheel cambers remain unchanged in all conditions including acceleration, braking, cornering, load and bumps. 

Body roll suppression usually conflicts with ride comfort, because the former requires stiffer spring and dampers while the latter is opposite. Nevertheless, clever suspension geometry may improve body roll without altering the ride. 

Suspensions are employed to deal with humps in the road surface helping to enhance ride comfort. When a car rides over a hump, the springs are compressed, storing the energy to provide shock absorption.

The energy will be released quickly when the springs bounce back. Dampers are employed to smooth and slow the bounce motion, which is called "damping".

Without dampers, the car will bounce up and down severely and quickly, and potentially provide an uncomfortable ride.

    Cabin Air Filters

    The cabin air filter is responsible for cleaning outside air entering the vehicle. Because up to 100,000 litres of air can be blown into the vehicle’s interior in less than an hour, it can easily become clogged with debris. Unfortunately, a blocked cabin filter will not be effective, resulting in a below-par heating and cooling system, and causing the air inside the vehicle to become more polluted than the air outside up to six times more. Similarly, bacteria and fungi can accumulate in the filter, leading to unpleasant smells in the cabin. Fitting a high-performance cabin filter, such as Delphi, is essential in eliminating these harmful pollutants and odours, safeguarding both you and the air conditioning (A/C) system.
