The biggest racecar suspension set up mistakes

Race car suspension set up serves multiple purposes,  as it is  more prone to wear and tear compared to regular car suspension. Its design is not only different, it is also essential in determining the overall performance of a race car. If you wish to find high quality suspensions and learn more about this particular car component. The main benefits of a good race car suspension system are:

  • It offers a stable platform for better vehicle control
  • It provides an improved isolation of the chassis and driver protecting them from shocks and jolts at high speeds
  • It allows the vehicle’s tires to stay in contact with the surface even if it is uneven
  • It dampens the oscillations created by rubber tires, springs and uneven surfaces.

The importance of a race car suspension set up is undeniable. However, race teams can still make errors when choosing their suspensions, because there are a lot of options in the market. Here are some common mistakes you should avoid when buying your race car components:

  1. Not testing

You cannot predict the perfect set up no matter how experienced you are, because there are too many variables. What is more, even the most ideal spec formula can fail you for the smallest reasons. In this case, you should forget about playing by the rules when choosing your suspension setting and rely on comparative testing.  Testing can improve the overall speed and dynamic of the race car, not to mention its control.  You can ask the help of a suspension manufacturer and they can  offer you a tested set up.

 

  1. Not checking the tire readings

The tyres are the most complex and important component of a race car set up, so you should carefully check the pyrometer temperature readings of the tyres during testing to see what is happening with the car with the new suspensions installed. Some tyres work better with a particular type of suspensions and the only way you can find a balance is through testing. For instance, a tyre that has better grip will require greater roll stiffness.

 

3.Not checking the spring frequency

Generally, race teams know their spring rates, but are not interested in the spring stiffness and roll stiffness of their vehicle.  You can measure the ride stiffness easily without using motion ratio calculation with a bounce test that measures the spring frequency directly. The front to rear roll stiffness should not have a difference larger than ten percent except special situations. Unfortunately, most race cars have a lower rear spring stiffness that makes the vehicle unbalanced and more difficult to control. If your rear roll stiffness is too low, you can change the springs, the rear ARB or the roll centre height.
