In this video, we will focus on the importance of right rear spring load in race cars, particularly for modified, street stock, and late model vehicles. The video explains that the correct load is essential for maintaining grip and traction when accelerating through corners. We will explain how to determine the correct load using a chart, spring rate, and spring compression, and he also discusses the impact of weight transfer and how to adjust it using turn adjustments and lead weights. Finally, we will emphasize the need to maintain the correct load throughout the setup process and how adding lead weight can improve grip without significantly altering the car's balance.
