Suspension tuning refers to the process of adjusting a vehicle's suspension system to improve its handling, comfort, and overall performance. This involves modifying components like shocks, struts, and springs to achieve the desired balance between ride quality and responsiveness. By fine-tuning these elements, drivers can enhance their vehicle's stability during cornering and reduce body roll. Proper suspension tuning can also help in adapting a vehicle for specific conditions, such as off-road driving or track racing, ensuring optimal performance in various environments.
