Square the car Most often this is done by taking off the wheels and hubs and placing the car into a set of alignment bars. All car manufacturers have different settings they prefer and I recommend following those. If you were to measure from the bottom of the car to a level surface underneath your left side heights are going to be somewhere around ¾ to 1 ½ inches while the right side will be about 1 ½ inches. This means that comparing ride heights with other handlers may not always be a proper apples to apples comparison but it will make sure your process is consistent. Because this is kids racing and they are not always easy to find doing without driver is the most common. Choose whether or not to complete these steps with or without driver and then always do it the same way for uniformity. Even though this step will be repeated later it is important to do it now at this point also to ensure the next steps are accurate. Approximate Ride Heights Put the car on a level flat surface and then set each corner to the height you want it in race trim. For asphalt this can be anywhere from 10 to 14 lbs for the right sides at the start of a race and between 5 and 8 for the left rear and 8 to 10 for the left front. Tire Pressures Each time the car is setup make sure to put the tires at the pressure you will race them to make sure that any other measurements taken are relative to how the car will be raced. Actual settings are not provided as they are different for each brand and model of car plus the class the driver is racing in.
