Race Car Spring Rates. This will put shock compression near 50 of its stroke when the car is resting at ride height. When in doubt choose a lower spring rate.
The most common type of spring used in race cars is the coil spring which is typically installed together with a damper see picture. Editor s note springs are one of the most important and noticeable parts of a car s suspension to consider when preparing it for track use choosing spring rates in the most effective ballpark rates for your application and desired use can be tough but the following is a good way to spend a little time calculating what might be the best optimal choice for you. Once the desired frequency has been established for a given corner axle you can now start calculating proper spring rates.

We are fortunate in circle track racing that we only turn left. It was in germany in the 1980 s when wilfried eibach engineered the first designs of today s legendary eibach race springs we still have saved a typenliste just one sheet of paper from the year 1986 which pictures the first 50 ers part numbers all metric 60 mm id inner diameter obviously this basic approach was spot on as. If we find the calculated spring rate with a 2 0hz front and 1 8hz rear suspension frequency yields spring rates that we feel are a bit too high or low we ll adjust sf to coincide with our years of experience choosing and testing spring rates on a wide range of track cars and race cars. So we can manipulate the spring rates on the four corners to.
