The KW Variant 2 "inox-line" coilovers are the perfect solution for drivers who want more than just outstanding looks and adjustable ride height. In addition to the stainless steel coilover struts, and corrosion-resistant components built for long term durability, the KW Variant 2 coilovers give you the ability to adjust the rebound damping characteristics with 16 clicks of adjustment allowing the fine tuning of the ride comfort or performance to their satisfaction. As with all KW coilovers our engineers develop vehicle specific damper settings which 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 on our KW Variant 2 coilovers you can have more direct influence on the handling or comfort of the car. With 16 precise clicks you can adjust the KW dampers (firmer or more comfortable) without affecting the the compression damping fine tuned by our engineers. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.

KW Variant 2 Coilovers Feature:

• Customized Suspension Lowering. KW coilover suspensions, KW height adjustable springs, and KW DLC Air Suspensions allow the suspension to be lowered within the vehicle's technical limitations. For example, our Street Comfort products allow for a customized ride height setting with mild suspension lowering from 10 - 50 mm, while the Street Performance products allow the maximum technically possible suspension lowering range from 45 - 85 mm, depending on the vehicle. This means that the suspension can be lowered to suit the personal needs of the user and, depending on the product category, a setting ranging from Comfort to Performance can be chosen.
• Composite Spring Seat. The KW coilover spring seat, also known as a spring perch, is constructed with a wear-resistant, friction-optimized polyamide composite material encompassing a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation while the stainless steel insert maximizes strength.
• Trapezoidal Threads. In combination with the Inox-Line stainless steel coilover struts, this guarantees the long-term functionality of ride height adjustability. In comparison to common coilovers, KW uses a friction-optimized trapezoidal thread which is less sensitive to dirt and requires less force to adjust. Its large cross-section also provides a higher load-bearing capacity.
• INOX-Line. KW's coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, Inox-Line coatings will not wear off while adjusting the suspension making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the trapezoidal thread in combination with the polyamide composite spring seat guarantees long term usability. Even after years the ride height adjustability is not affected.
• Rebound Adjustment. The rebound stage damping is precisely tuned to the respective vehicle at our in-house drive dynamics test facility, delivered in the middle of the range out of the box. Individual customization can be achieved in 16 precise clicks, allowing you to choose between more comfort or more body control. The two-stage patented TVR-A technology allows the oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides major improvements in ride comfort without influencing the high-speed.
• 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.
• KW 7-Post Driving Dynamic Test. Used regularly by automobile manufacturers and international race teams, KW's in-house 7-post drive dynamics test facility is utilized to optimally tune KW coilover suspensions according to the design and target group. The 7-post drive dynamics test facility is essential for fine tuning along with actual on-road evaluation on public roads and race tracks. In objective laboratory conditions, which can be reproduced at any time, we work everyday to give our customers the internationally-esteemed KW driving experience.
• Technical Component Report. The technical component report is always included in the package and outlines the guidelines for lowering the suspension of the respective vehicle. The technical component report ensures the vehicle remains usable when set within the guidelines provided in the installation instructions, allowing for an inspection and subsequent entry into the vehicle documents to be carried out without any problems. The technical component report also includes precise vehicle classification, requirements, and tips for safe fitting.These reports are required for road legal approval in many countries, check local laws.

KW is the Benchmark for coilovers. KW Variant 2 "inox-line" coilover rewards the sporty driver with its harmonious pre-configured setup. For each vehicle our engineers develop a specific damper setup and spring rate to increase the driving pleasure with an optimal balance of sportiness and practicality. As with all KW coilovers, the engineers at KW develop the vehicle-specific KW damper tuning and spring rates with comprehensive testing on the Nurburgring Nordschleife and in the KW 7-post chassis dynamics test center. 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 2 "inox-line" coilovers, body roll will be reduced during compression giving you the benefit of a more genuine and direct sporty handling while driving.

Height adjustable front and rear axles (front axle threaded strut housings, rear axle adjustable springs + dampers). Not for vehicles with electronic damping. Valving is adjusted by adjustment knobs, rebound is only adjustable if the top of the piston rod is accessible. This will depend on the design of the vehicle.
