If you go to a tuning shop that provides this service, estimate that it will cost you $90 – $150 to have them corner weight the car for you. Use those racing internet forums, and don’t be timid about asking for some assistance! Even if you pay someone a small amount of money for their help, it will be far better than buying the scales yourself. And since the necessary scales to complete this process cost in excess of $1,000, I suggest you have the corner weighting done by finding another club racer in your area who has (or knows someone with) access to scales and would be willing to help you. Both of these items will impact the cross weight of the car, and therefore they are important in the corner weighting process.Ĭorner weighting can be a complicated process for you to complete without someone who is experienced helping you. A good starting point would be ¼ – ½ tank of gas. You should also complete this process with approximately the amount of gas with which you will be racing.

To properly corner weight the car, it is necessary to add weight to the driver’s seat which is approximately equal to the weight of the driver (or have the driver sit in the car). This approach is commonly used in oval track racing. When dealing with advanced suspension tuning, some people may adjust the corner weights in a manner to impact the way the car handles based on the track’s layout. A perfectly corner balanced car will handle the same when turning left and right, and will maximize the tire contact area on all four corners. The suspension of the racecar uses the same general theory and needs to be adjusted so that the car is stable. If one leg is longer or shorter than the others, the table will rock and thus be unstable. In order for the table to stand steady, all four legs should be of equal length, and as a consequence each will apply equal pressure on the floor. Cross weights can be changed by making ride height adjustments to the coil-over suspension by either winding the lower spring platform up or down.Īn analogy which is commonly used is to imagine that the car is a four-legged table. Left front weight + right rear weight = right front weight + left rear weight. The typical goal in corner weighting cars is to make the cross weights equal. When looking at corner weighting, the cross weight (diagonal weight) is the most important component. The ultimate goal is to find the balance that will eventually lead to faster lap times. By changing the weight distribution on the car, you affect the way your car will behave when cornering. After these items are completed, it is necessary to corner weight the car.

Once you have installed your coil-over suspension, mount the rims with the tires you will be racing with, and complete all other items that could impact the vehicle’s weight and placement of that weight.
