Suspension is the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels. Suspension systems serve a dual purpose — contributing to the car's roadholding/handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps, and vibrations,etc.
In our time it is very usual to see numerous cars, from commercial cars to sports cars fitted with different types of suspension on them. The exterior fashioning and aerodynamically well-organized design for reduction of engine load which reflects in the reduction of fuel consumption and producing the down force for the stability are the two essential factors for an effective operation in the modest world. An aerodynamically optimized car body will result in a change of lift and drag forces the car experiences and thus influence the cars overall performance, fuel consumption, safety, and stability.
