Pro Sport Digressive Series Coilover Kit

The Yellow Speed Racing Pro Sport Digressive Series Coilovers are engineered to offer exceptional handling characteristics for the Subaru Impreza 2017-2023 (GK/GT), while also aiming to maintain a balanced ride comfort. Digressive valving works by providing increased damping resistance at low shaft speeds, which is crucial during activities like turning, accelerating, and braking. This results in enhanced chassis control and a more planted feel. Conversely, at higher shaft speeds, such as when encountering potholes or bumps, the resistance tapers off, allowing for more compliant shock absorption and a smoother ride. This technology aims to strike a balance between performance and everyday drivability. Key specifications include front pillowball upper mounts with camber plates for adjustable alignment, and rear aluminum upper mounts with hardened rubber bushings for durability and reduced NVH. The spring rates are set at 7k for both the front and rear, providing a performance-oriented stiffness. While these coilovers offer improved control, reduced body roll, and the ability to absorb larger impacts well, they may provide a firmer ride at low speeds compared to stock suspension. Potential NVH increases are also a consideration. They are best suited for enthusiasts who enjoy spirited driving, autocross, or occasional track use, and prefer a more performance-oriented, connected driving experience. It is important to note that this specific kit does not fit WRX or STI models, and some configurations may not be compatible with vehicles equipped with a Drive Mode Select System. Additionally, please allow 3-4 weeks for shipping as each system is custom-built to order.
