89-94 Nissan 240 SX (S13) Variant 3 Coilovers | KW

Unparalleled street performance bred from motorsports heritage

Independently adjustable in rebound & compression. 

 

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 Variant 3 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.
 
KW’s coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof.
  

Features

 

Customized Suspension Lowering

KW coilover suspensions, KW coilover springs, and KW DLC AirSuspensions allow the suspension to be steplessly lowered within the framework of the certified technical component report.

 

 

Rebound

The rebound stage damping is precisely tuned to the respective vehicle on our in-house drive dynamics test facility, with the setting fixed in the mid range. 

 

Compression (Low)

Two-Step Compression Stage Valve with Low-Speed
The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for small and large volume flow. 
 
 

Composite Spring Seat 

The KW coilover spring seat is made from a wear resistant and friction-optimized polyamide composite material with a stainless steel insert.
  
 

Trapezoidal Thread 

The Perfect Height-Adjustable Coilover
In comparison to common coilovers, KW uses a friction -optimized and dirt insensitive trapezoidal thread.
 
 

Reservoir 

The use of KW reservoirs provides additional volume for additional oil and additional cooling capacity for particularly high-stressed systems. 
 
 

KW 7-Post Driving Dynamics Test 

Testing Like in Formula 1
Used regularly by automobile manufacturers and international racing teams, KW’s in-house 7-post drive dynamics test facility optimally tunes the KW coilover suspensions according to the design and target group.
 
 

Technical Component Report 

The technical component report is always included in the package and outlines the individual options for lowering the suspension of the respective vehicle.
 

 

TVR-A Rebound Stage 

(Twin Valve Rebound - Adjustable)
The two-step, patented TVR-A technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows.
  
 

TVC-A Compression Stage 

(Twin Valve Compression Adjustable)
The patented compression stage valve with TVC-A technology features two separate spring pre-tensioned valves for low and high volume flows.
 
 
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 Variant 3 "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 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.

 

 

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 Variant 3 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 Variant 3 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 Nürburgring Nordschleife and in our KW 7-post Driving Dynamic Test Center. With a KW Variant 3 coilover kit the driving experience is more dynamic and direct. 
 
You are not buying a mass produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that has all developed in-house. With the KW Variant 3 "inox-line" coilovers, rolling motion of the body will be reduced during compression giving you the benefit of more direct handling and confidence while driving.
