The Eibach PRO-KIT for the 2014-2018 Ford Focus ST is the ultimate solution for street-driven vehicles seeking both performance and visual enhancement. This legendary spring system lowers the car’s center of gravity, reducing squat during acceleration, body roll in corners, and nose-dive under braking. When paired with Plus-1 or Plus-2 wheels and tires, the PRO-KIT perfectly fills the wheel arches for a sharp, aggressive stance. Using a proprietary progressive spring design, Eibach’s PRO-KIT delivers the optimal balance between ride quality and high-performance handling. Every set is engineered and tested by Eibach’s suspension professionals for exceptional durability, safety, and performance.
