Meet the Mangione Press Corps Ashley Rojas, Abril Rios, and Lena KW Coilover Kit V2 BMW 4 Series. KW V2 INOX LINE coilovers are the perfect solution for drivers who want more than just outstanding looks and adjustable ride height. In addition to stainless steel coilover struts, and corrosion resistant components built for long term durability, KW V2 coilovers utilize TVR A (Twin Valve Rebound Adjustable) technology that allow Adjustment of the rebound damping characteristics with 16 clicks so you can fine tune the ride comfort or performance to your satisfaction. As with all KW coilovers our engineers develop vehicle specific damper settings that undergo comprehensive testing on the Nurburgring Nordschleife and in our KW 7 post Driving Dynamic Test Center. With a KW coilover kit the driving experience is more dynamic and direct. With the rebound adjustability you have a more direct influence on the handling or comfort of the car. With 16 precise clicks you can adjust the KW dampers (more firm or more comfortable) without affecting the compression damping fine tuned by our engineers. The two stage, patented TVR A (Twin Valve Rebound Adjustable) technology enables a small volume of oil flow through an adjustable, conically shaped, low speed bypass during low damper speeds, while at high damper speeds, the main rebound stage valve opens allowing a larger volume of oil to flow. This provides a big improvement in terms of ride comfort without influencing the high speed range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control. With KW V2 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension and adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar. Installation Instructions Installation Instructions Installation Instructions Installation Instructions Installation Instructions Installation Instructions TVR A (Twin Valve Rebound Adjustable) technology allows oil to flow passed an adjustable, conical low speed bypass during slow damper speeds, while at higher speed, the main rebound stage valve opens for maximum fluid displacement. Elastomer Bump stop with integrated dust protection system prevents water and dirt particles reaching the piston rod and seals. The highly resilient bump stops act as dynamic load limiters while maintaining ride quality and durability. Adjustable rebound damping allows you to influence the ride characteristics. Paired with vehicle specific spring rates precisely tuned by our engineers, V2 coilovers allow you to choose between more comfort or increased sportiness. Composite spring perch made from wear resistant, friction optimized polyamide composite encompassing a stainless steel insert. The polyamide composite prevents oxidation while the stainless steel insert maximizes strength. Inox Line Stainless Steel Truly Permanent Corrosion Resistance. Inox Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Seamless Ride Height Adjustment the corrosion resistance of the Inox line stainless steel and composite perches means easy ride height adjustability to help you dial in your preferred look KW suspensions V2 coilovers are hand built by our expert team and given a uniquely individual serial number at our headquarters in Fichtenberg, Germany. Every KW damper is dyno tested to ensure accuracy and preset to our recommended shock settings before being released for delivery.
