Driving pleasure³: KW coilovers for all current BMW M3 (G80) and BMW M4 (G82) with rear-wheel-drive or xDrive (all-wheel-drive)!
For many years, the suspension manufacturer KW automotive develops several suspension components for the motorsports and accessories program of the car manufacturer BMW. The KW V3, KW V4, and KW V5 Clubsport coilovers are now available for the current BMW M3 and BMW M4 of the G8x generation. Even the KW V3 coilover suspension, which is separately adjustable in compression and rebound, provides a significant increase in the driving dynamics of the BMW M3 (G80) sedan and the BMW M4 (G82) coupe.
On the other hand, the redesigned KW V4 is a further development of our standard suspension for the limited BMW M4 GTS (F82) and KW Clubsport suspension kit. Similar to the standard suspension developed by KW for the BMW M4 GTS (F82), the new redesigned KW V4 coilover suspension kit is adjustable independently in the low-speed and high-speed forces of the compression damping as well as the low-speed rebound damping. The KW V4 coilover suspension is our recommendation for all BMW M enthusiasts who simply expect more from their BMW M on the road.
The BMW M3 (G80) and the BMW M4 (G82), which are already lowered in standard production, can be further lowered by installing the KW V3, KW V4 and KW V5 Clubsport. According to the technical parts certificate, an additional lowering of 20 to 35 millimeters at the front axle and 15 to 30 millimeters at the rear axle is possible despite the factory-lowered BMW M4 body. The KW V3, KW V4 and the KW V5 Clubsport enables the same adjustment range in terms of lowering for the BMW M3 sedan (G80). This roughly corresponds to a lowering of 50 millimeters on the BMW 4 Series coupé (G22) and 60 millimeters on the BMW 3 Series sedan (G20).
The KW V5 Clubsport in the BMW – No Need to Decide Between Street And Track Use
Thanks to numerous setting options, the KW V5 Clubsport is the perfect choice for those that crave the streets and track. We deliver the V5 Clubsport in the best-fitting setup for your car model. Nevertheless, you can easily adjust the basic damper setup at any time. Here, further adjustments in compression and rebound (high-speed and low-speed are possible). You can adapt your car setup to its weight, tires, or circuit depending on the use. In the case of the BMW M models, KW damper cartridges were used in a monotube design. Inside the M3 and M4, the V5 Clubsport also enables continuous lowering of 20 to 35 millimeters at the front axle and 15 to 30 millimeters at the rear axle. The result: The M models get a sportier look and better street connection.
The KW V4 coilover suspension kit - simply more BMW M power for the road
On the M4 GTS standard suspension, we still worked with a reservoir and installed the adjustable low-speed and high-speed compression valves there. In contrast, we redesigned the entire damper setup for the next generation of the KW V4. The valves, which can be adjusted separately in the compression’s low-speed and high-speed range, are positioned in a compact valve housing laterally on the strut and damper housing for the rear axle. The golden adjustment wheel can be used to set the damping in high-speed compression with 14 clicks and with the purple wheel, the damping characteristics in low-speed compression can be fine-tuned with 13 clicks.
When the valves are open, the compression is reduced and the M4 body dives faster. The compression influences the diving speed of the damper piston rod to a certain extent. Moreover, the compression has an impact on the body's pitching and rolling movements as well as its turn-in behavior. If the compression is increased, the piston rod dives more slowly. Consequently, the vehicle becomes more stable during steering movements. The turn-in behavior gets more precise the tighter the compression is tuned.
The low-speed rebound, which is equally adjustable on the KW V4 coilover, has a direct effect on the operating speed when the piston rod de-compresses. It controls with 16 clicks how fast the spring gets back to its original position. So to speak, the diameters of the rebound valves open for a more comfortable road behavior and close for a more firm tuning. Braking, accelerating and steering, for instance, are low-speed stimuli in everyday driving. The preset Sport+ tuning of KW V4 can be altered to a comfort-oriented road setup with just a few clicks if desired.
Typical high-speed excitations occur when the wheel rolls over bumps or transverse joints. Anyone who drove rapidly over a badly constructed road certainly noticed that this makes the whole car become unsteady. Nevertheless, a suspension that disposes of shock absorbers with adjustable multi-valve technology can integrate much more calmness into the entire body structure, even with a sporty set-up. The possibility of tuning the dampers of KW Variant 4 in accordance with one’s individual everyday driving profile makes the KW coilover made in Germany the first choice when it comes to BMW tuning.
The KW V3 - the coilover kit for every BMW M fan who demands more as stance
Actually, the KW V3 is similar in its setup and design philosophy to the BMW M Performance suspension we developed for BMW M for the BMW M3 (F80) and BMW M4 (F82). The KW V3 enhances the M3 sedan and M4 coupe and provides a phenomenal driving experience while making the typical oversteer of modern cars much more neutral and easier to control. The KW coilover suspension features sporty handling and convincing ride comfort - and this even with a maximum lowering.
