Saab 99 Cutaway Drawing in High quality KW Coilover Kit V3 2021+ BMW 4 Series Coupe 4WD (G22) w o Electronic Suspension. The KW V3 Leveling coilovers are ideal for drivers who are looking for the improved driving dynamics of a KW V3 coilover suspension with the ground clearance near that of a stock vehicle. The KW V3 Leveling coilovers are for drivers who frequent poorly maintained roads or use their car as a daily driver in environments where maximum lowering is not advised.? The KW V3 Leveling coilovers have separate and independently adjustable low speed rebound and low speed compression adjustments that utilize patented TVR A & TVC A multi valve technology. This allows you to further influence the preset damping characteristics to achieve the ideal ride you are looking for. If necessary, the seamlessly adjustable KW V3 Leveling coilovers allows for a subtle height adjustment to even out the car body front to rear and in some cases, you can even achieve a slight lift, providing additional ground clearance. With the KW V3 Leveling coilovers, the rolling and pitching movements of the vehicle body are reduced during compression and rebound, so you benefit from unadulterated directness and sportier handling when driving. 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. TVC A (Twin Valve Compression Adjustable) technology patented compression valve allows fine tuning of low speed. During sudden high piston speeds, the low speed needle and main valve blow off feature open to maximize flow. 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. Road legal motorsports technology featuring independent rebound and compression adjustability and application specific spring and damper tuning resulting in unparalleled performance. KW V3 Leveling coilovers are hand built by our expert team and given a uniquely individual serial number at our headquarters in Fichtenberg, Germany.
