Version RR Coilover System

The Ksport Version RR coilover system is engineered exclusively for road racing applications, prioritizing maximum handling and acute responsiveness. This system features aggressive spring rates and valving, complemented by 36 levels of simultaneous compression and rebound adjustment to fine-tune ride characteristics to your specific needs. Constructed with a focus on performance and durability, the Version RR coilovers employ a monotube design, which excels at dissipating heat and allows for more precise damping adjustments compared to twin-tube designs. Many applications incorporate pillow ball upper mounts for maintaining suspension geometry and providing a more direct driver feel, with some offering camber adjustment directly through the mount. Height is adjusted via an adjustable lower mount, preserving suspension travel. The majority of the components, including mounts, are crafted from lightweight and durable 6061 billet aluminum, while the steel shock bodies are electroplated with zinc for enhanced rust and element resistance. The internal valving is carefully matched to the installed springs, ensuring optimal ride quality and reliability. This specific Version RR Damper System with Front Camber Plates (Part # CBM090-RR) is designed for the 2006–2011 BMW 325i, 328i, 330i, 335d, 335i, and 335is models with the E90/E91 Chassis Sedan. The spring rates are set at 18kg/mm (1008lbs/in) for both front and rear.
