KW V4 Coilovers – BMW M2
With the KW Variant 4 coilover suspension “inox-line” we combine our leading racing technology with a significant increase of everyday suitability for numerous high-performance vehicles. This enables an independent adjustment of the rebound stage damping as well as low-speed and high-speed compression stage damping. KW supplies the Variant 4 with a vehicle-specific performance setting. With the adjustable dampers, drivers can – if necessary – quickly change to a comfort setting by using the integrated setting dials on the damper.
Setup – factory-set pre-configured damper setup with separately 3-way damper adjustment
The three-way adjustable high-performance dampers with the independent setting of the rebound stage by the “TVR-A”-technology as well as the low-speed and high-speed compression stage damping by the “TVCLH-A”-technology are based on the successful racing technology of the multiple overall winner of the ADAC Zurich 24h Nürburgring race and are depending on the vehicle-specific version, braced with aluminum top mounts. The new KW coilovers Variant 4 are exclusively developed for selected high-performance-vehicles, which due to the sophisticated KW suspension technology can benefit from safer driving at the limits of their driving dynamics.
TVR-A rebound stage damping (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. This provides a big improvement in terms of ride comfort without influencing the high-speed in the safety-relevant range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVCLH-A compression stage damping (Twin Valve Compression Low Highspeed – Adjustable):
With 6 precise clicks in low-speed and 14 precise clicks in high-speed range of the compression stage damping, the cross sections in the valves are decreased or increased, in order to achieve either more or less compression stage damping. The “TVCLH-A”-technology has a blow-off characteristic with large cross-sections which allows high low-speed forces for an optimum bracing of the vehicle body without raising the body in the case of wheel-induced high damper speeds (driving over curbs). The separate low and high-speed setting is always supplied with an additional rebound setting (“TVR-A”-technology) for an in dependent 3-way damper setting.
CUSTOMIZED SUSPENSION LOWERING
Fulfills Every Wish
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. For example, our Street Comfort products allow for a customized height setting with gentle 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.
REBOUND STAGE ADJUSTMENT TECHNOLOGY
Two-Step Rebound Valve with Adjustable KW TVR-A Rebound Stage Damping Technology (Twin-Valve Rebound Adjustable)
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. Individual customization can be achieved in 16 precise click positions, allowing you to choose between more comfort or more body control. The two-step patented TVR-A technology allows the damper 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 improvement in ride comfort without influencing the high-speed in the safety-relevant zone.
COMPOSITE SPRING SEAT
Because the Devil is in the Details
The KW coilover spring seat is made from a wear resistant and friction-optimized polyamide composite material with a stainless steel insert. In contrast to the anodized aluminum adjustable spring seats, the polyamide composite material prevents any possible oxidation. In combination with the Inox Line, this guarantees the long-term functionality of the height setting.
The Perfect Height-Adjustable Coilover
In comparison to common coilovers, KW uses a friction -optimized and dirt insensitive trapezoidal thread that displays low adjustment forces. Its large cross-sectional area allows for a higher load-bearing capacity.
The Only Truly Permanent Corrosion Resistance
KW’s coilover suspension struts are manufactured from high-quality stainless steel that is rust-proof. In contrast to other solutions, coatings will not wear off while adjusting the suspension settings making KW coilover struts 100 percent corrosion resistant with an unlimited lifespan. Lowering the suspension using the dirt-insensitive trapezoidal thread in combination with the polyamide composite collar guarantees long driving pleasure. Even after years the stepless suspension lowering is not affected by environmental influences.
KW Twin-Tube Technology Knows No Limits
The use of KW reservoirs provides additional volume for additional oil and additional cooling capacity for particularly high-stressed systems. The reservoir, which is filled with low gas pressure, can be fitted anywhere and accommodate the adjustable compression stage valve to provide the damper with more working space.
7-POST DRIVE DYNAMICS TEST STAND
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. The 7-post drive dynamics test facility is essential for perfect fine tuning along with road trials 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.
