DYNAMIC PRO SPORT coilovers are designed and developed for motoring enthusiasts desiring excellent handling without sacrificing ride comfort. This suspension system features 33-way adjustable dampening settings and full length ride height adjustment to meet every driver’s handling desires. Pillowball mounts and adjustable camber plates are included for front and rear on most kits to increase steering response, while aluminum upper mounts with hardened rubber bushings are used on some applications for noise reduction. This suspension system is ideal for daily driving and occasional track use. Vehicle ride height can be lowered at least 2.5" or more on most application. 

A steel lower bracket is utilized for MacPherson strut type to increase rigidity for safety (where applicable). For most MacPherson strut models, the brake line bracket is welded manually perfectly to the steel lower mount. A high quality forged alloy aluminum lower bracket is used for Double-A Arm strut type (where applicable). The steel/aluminum lower bracket is processed with electroplated/ anodized surface treatment to prevent corrosion or rust in the harsh conditions of motorsport. The vehicle ride height can be adjusted easily with the lower bracket by winding up and down to drop and raise. With the lower bracket, it allows maximum suspension travel without affecting the shock stroke.

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.
