H&R 17-21 Audi A4 Premium/Premium Plus/Prestige (2WD) B9 Street Perf. Coil Over Kit (w/o MRC)

Cutting-edge motorsports technology for more performance on the road. Like every suspension product developed by KW automotive, the suspension manufacturer, and manufactured in Germany, the KW V3 Coilover suspension kit also provides a significant plus in safety reserves in road traffic. Thanks to the chassis with its high-quality dampers, springs, and elastomer spring elements, pitching and rolling movements during load changes such as evasive maneuvers, cornering, acceleration, and braking are significantly reduced. The braking distances are also shortened. Thanks to improved support and feedback, drivers not only feel safer but driving in everyday life becomes even safer. With compression and rebound stage damping, that can be set separately and independently of each other, the damper setup can be customized to your personal driving preferences or vehicle changes such as weight, tire characteristics, or altered vehicle rigidity. True performance optimization is only possible with this unique, patented system. For example, this allows the compression damping force to be increased and get more grip from the tires, to improve cornering behavior and reduce squat without simultaneously altering the rebound stage damping which is optimally matched to the spring rate, a scenario which results in reduced grip and the associated loss of performance. The KW V3 coilover kit is the ideal tool for performance-oriented drivers and experienced tuning enthusiasts who place a strong emphasis on the overall performance of their suspension. The Variant 3 features patented TVR-A and TVC-A technology that provides separately adjustable rebound and compression damping. The extensive adjustment range of the independently configurable rebound and compression make it easy to directly influence the steering behavior, directional stability, grip and handling characteristics for confident and repeatable results at the limit of driving dynamics.
Unparalleled street performance bred from motorsports heritage, the patented KW-valve technology -or the separate Adjustment -f rebound and compression damping, allows you to individually adapt the vehicle-specific base setup.
For over 20 years, KW automotive has been the market leader and driving innovation as a manufacturer of individual suspension solutions for the road and in all types of motorsports. No matter where in the world, gearheads, automobile manufacturers and reputable tuners rely on our KW coilovers “Made in Germany”. Every KW coilover kit undergoes extensive stress testing before production and is developed and manufactured exclusively in our company headquarters in Fichtenberg, a small in town in Germany, to meet the high standards of our KW quality management. For us as a German manufacturer, it goes without saying that our KW coilover kits will exceed the original equipment manufacturer quality and offer useful and innovative solutions. With an application list comprising more than 4,600 options KW guarantees an outstanding selection backed by our Limited Lifetime Warranty.

• 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 street performance.
• KW suspensions V3 coilovers are hand built by our expert team and given a uniquely individual serial number at our headquarters in Fichtenberg, Germany.
• Each damper is dyno tested to ensure accuracy and preset to our recommended shock settings before being released for delivery.

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 afte r years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.
For sporty drivers who want more than just outstanding looks and lowering within the tested Adjustment -angle, the KW V2 “INOX-LINE” coilovers are the perfect suspension featuring TVR-A adjustable rebound damping technology.
