Fitment Information

• BMW Z4 E85/E86 Coupe/ Roadster (2003, 2004, 2005, 2006, 2007, 2008)

Specs & Features

• Lowering adjustment ranges:
• Front: 0.8″-2.0″
• Rear: 0.6″-1.5″
• Spring Rates:
• Front: 285
• Rear: Progressive
• Stainless Steel Twin Tube Shocks
• Limited Lifetime Warranty through KW
• Professional install and setup recommended
• 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.
• Each damper is dyno tested to ensure accuracy and preset to our recommended shock settings before being released for delivery.
• 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.
• 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.
• KW suspensions V3 coilovers are hand built by our expert team and given a uniquely individual serial number at our headquarters in Fichtenberg, Germany.
• Road legal motorsports technology featuring independent rebound and compression adjustability and application specific spring and damper tuning resulting in unparalleled street performance.
• 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.
• 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.

Product Description

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.

Specifically Engineered Setup Vehicle specific with separately adjustable rebound and compression damping

The KW V3 “inox-line” 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 V3 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.

TVR-A Technology

The two-stage, patented TVR-A (Twin Valve Rebound – Adjustable) technology enables a small volume of oil to flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while in the case of higher damper speeds, the main rebound stage valve opens allowing a larger volumn of oil to flow. This provides a big improvement in terms of ride comfort without influencing the safety-relevant high-speed range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.

TVC-A Technology

With 12 precise clicks, the KW V3 coilovers utilize TVC-A (Twin Valve Compression – Adjustable) technology and can increase or decrease the flow of valve to achieve either more or less low speed compression damping. During sudden high speed impulses the spring loaded needle valve and the spring loaded main valve open to their maximum valve cross section, acting as a digressive blow-off characteristic to avoid transmitting undesired forces through the suspension into the chassis. This provides a better platform for the vehicle body and at the same time offers more comfort than with conventional valve technology during high wheel acceleration. The dampers come preset to our baseline shock settings right out of the box providing an optimal starting place for your car while providing a wide adjustment window for true performance optimization.

Continuous Ride Height Adjustment

With KW V3 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension with 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.

The Benchmark for Coilovers

As with all KW coilovers our engineers develop vehicle specific damper and spring specifications which undergo comprehensive testing on the Nrburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center. With a KW V3 coilover kit the driving experience is more dynamic and direct.

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.
