Riaction GP1 Coilovers for 2015-2020 BMW M4 3-Bolt (F82/F83)

Riaction GP1 Digressive Coilovers for the 2015-2020 BMW M4 3-Bolt (F82/F83) have much more low speed control in comparison to a Linear valve in the Riaction GT1 Coilovers. The resistance rate on the digressive valve increases as shaft speeds increase, but only to a pre-determined level. The digressive valving then has resistance that tapers off and as the shaft speed continues to increase, the resistance remains constant. This setup will do a better job of managing unwanted body motions while also still providing a comfortable ride.

The digressive coilover system is great for street use, canyon carving, and track days.

Each set of Riaction USA coilovers are made from high quality materials with precision design, to ensure a reliable and durable product. Riaction proudly stands by all of their products, and each Riaction GP1 Coilovers kit comes with a 2 year warranty.
