Premium Competition coilovers are designed and developed for vehicles that participate in track events and competition racing often. Through years of competition and testing, we have made countless improvements in our setups for racing use. As a result, we have developed the most durable and competitive damper system on the market. Spring rates and shock valving are made specifically for competition use to make the vehicle more controlled and balanced.

This suspension system features 33-way dampening adjustment and full length ride height adjustment to accommodate every driver’s needs. The lower mounts are manufactured from lightweight alloy aluminum to reduce unsprung weight. The pillow ball top mounts are used on McPherson struts for maximum handling and performance. The Premium Competition coilovers feature stiffer spring rates than our Dynamic Pro Sport coilovers, as well as larger valving.

High quality components are adopted to ensure product durability and stability. Each application is test fit and completely road tested to guarantee perfect performance and comfort.

Please note that ALL of our coilovers are hand built and made to order. Please allow 2-3 weeks for delivery.
