![]() Knowing this can help us to make educated changes to a car where we like the springs and shock settings but want to make minor adjustments to the car’s handling. Moving the weight ballast forward or increasing the split between the front and rear ride heights will also have this effect. When you do this the car will tighten especially on exit (where we need it this week). You are simply lowering the height.Īs you lower the front suspension you increase the cross weight (shift the center of gravity towards the front) of the car. If you lower the car equally in steps you should not notice much difference in handling or wear as you are not changing the “cross weight” of the car. Keep in mind that as you adjust the car, uneven adjustments will have adverse effects on the handling. Once set we will use a grease pen or similar implement to mark the position. ![]() This is similar to real life as we always “count the turns” we make on a spring perch and keep note of it. You will want to “step” the car down, first at the front and then at the rear slowly bringing the car down yet monitoring the setups to know your limits. Count the amount of “clicks” you make and make equal adjustments to the fronts and rears as pairs. We accomplish this task by adjusting the “spring perch.” Take note of the ride height as you make adjustments. We use a combination of the right spring/shock settings in addition to lowering the car to the lowest we can get it (especially in front) to try and “seal” the front and side skirts creating even airflow around the car. The trick however is to get enough play in the suspension to allow the front end to dive in the corners and remain “sealed” through the turn without bottoming out. Decreasing ride height reduces drag from air moving under the car and therefor increases speed. ![]() The first order of business is how to lower your car. We will discuss our theory on using a combination of lower ride height, the right amount of tape and softer shocks/springs to create a setup that handles well in and out of the draft, has speed off the corners and runs consistent lap times. Seeing as we are at a speedway this week, it seems an appropriate time to discuss aerodynamics and how your setup will affect the car in and out of the draft. So the first adjustments you may want to make here, drawing from our previous lessons, are to lower the track bar, soften the springs and increase the forward weight distribution. The base setup is inherently loose and with ambient temperatures in the eighties, it’s like driving on ice. By now you should be familiar with most of the common changes we can make to the chassis of a race car to adjust its handling, control its temperatures and increase its speed off the corners and through the straights.
