Build A Faster Car - helping drivers engineer

Higher spring frequency are frequently used in the rear of a car to produce what is known as a flat ride. With a rear spring frequency slightly than the front, the rear of the car will oscillate in a sightly shorter amount of time. Done correctly, the front and rear of the chassis will complete one oscillation at exactly the same time, reducing pitching in the chassis. This article will elaborate a bit on the subject, and show how damper tuning can make this feel even better.

Coil bind happens when all the coils of a spring are stacked on top of one another and the spring cannot compress any further. When the spring cannot compress any further, any additional force gets transmitted directly on the chassis and tires, leading to very high amounts of stress on those items (and the driver). A spring that cannot compress any further is said to be at its solid length or bound length.

The modern bump stop is more properly called a jounce bumper. Made from urethane and cut to varying sizes, today's bump stops are an integral part of most factory suspensions. Knowing their effects on the suspension is as important- if not more so- than that of your main springs. This page explores their effects when installing springs that lower a production car.
