Leaf Springs and Cornering Performance​

Tracking Behavior​

Leaf springs can exhibit lateral movement during hard cornering. This is due to their design, which allows some flex and steer. The amount of lateral movement can vary based on several factors, including the type of bushings used and the overall setup of the suspension.

Factors Affecting Tracking​

Recommendations for Improved Handling​

By addressing these factors, you can improve the tracking and overall performance of leaf spring-equipped vehicles during hard cornering.
