Construction & Design

The Bilstein B12 (Pro-Kit) suspension system features a meticulously engineered combination of high-performance dampers and progressive springs. The dampers utilize a monotube design with a digressive piston, which allows for precise control over a wide range of driving conditions. This design ensures consistent damping force, reduces brake dive, and improves handling during aggressive cornering or uneven road surfaces.

The Eibach Pro-Kit springs are crafted from high-tensile steel with a progressive spring rate, providing a smooth ride over rough roads while delivering the desired lowering effect. The springs are powder-coated for corrosion resistance and feature a precise fitment to ensure optimal suspension geometry. Together, these components create a suspension system that is both durable and performance-oriented, with a focus on maintaining factory-like ride quality while enhancing handling characteristics.
