Performance Suspension
Street Use
Springs
Springs can be used to lower or raise the height of the vehicle. Lower springs cause the cars center of gravity to lower. This can be a great improvement for handling. Additionally, the springs may also be much stiffer then stock springs.
Shocks
When upgrading other suspension parts, such as the springs, it is a good idea to have new shocks installed. Normally, the cost does not change when having a mechanic install both springs and shocks. Changing the height of the springs will put more pressure on the shocks, so new ones that can handle the additional compression are recommended. If the stock shocks are left on they will wear out much faster

Coilovers
If you are looking to upgrade both the springs and shocks, coilovers can be a great upgrade. Coilovers are a combination of springs and shocks that are flexible and can be adjusted. Therefore, you can lower and raise the vehicle depending on the driving environment. For instance, a truck may need to be lifted for off road driving. Then it is lowered when back on the road.

Stress Bars
To reduce any stress on the strut towers when turning, an upper stress bar can be installed. These bars reduce twisting and flexing when cornering and are very easy to install.
Sway Bars
When turning at high speeds and the vehicle is leaning a lot, feeling like it is falling over, then new sway bars are needed. Look for a sway bar that is part of an anti roll kit. The new upgraded sway bar should be stiffer and thicker than the stock sway bar. Because the bar is stiffer, it will keep the car flat when turning.
