With three-way high-performance dampers, the KW Variant 4 coilover suspension for BMW M8 (F92), and BMW M8 (F92) Competition is an ideal way to combine the demand for a continuously adjustable lowering with increased handling, ride comfort, and driving safety. The damper technology developed by KW automotive, which is also used in the original equipment of the limited production series BMW M4 GTS, ensures a significant plus in cornering stability even at high velocities.
The body's tendency to roll in fast corners is reduced. " During the development of our Variant 4, the focus was on driving fun with a gain in driving and especially lateral dynamics. With their adjustable multi-valve KW technology, our dampers also increase driving comfort. This technology has already convinced the trade press several times, including the KW shock absorbers used in the M4 GTS ex works.
Through the independently adjustable compression and rebound damping in the low and high-speed range, our factory-set performance setting can be changed at any time to a drive comfort-oriented setup". With 16 precise clicks, the rebound forces can be set for stiffer handling or more ride comfort. Using the two compression adjuster wheels directly on the damper, it is precisely possible to adjust the steering behavior and other parameters such as ride comfort and tire grip. With six clicks in low-speed pressure (seven characteristic curves) and 15 clicks in high-speed compression (16 characteristic curves), the KW Variant 4 allows a large tuning range for an individual damper setup. In addition to the "Performance Setup" preset from the factory, our technical documentation also includes a recommended "Street Setup" for more driving comfort in the BMW M8.
The KW valve technology also features a blow-off characteristic. The resulting high low-speed damper forces provide support for the vehicle body without causing the body to lift off at wheel-excited high damper speeds (crossing bumps). Just a few clicks give the BMW more driving dynamics or ride comfort - depending on the individual settings. When converting to the KW Variant 4 coilover suspension kit, a so-called cancellation kit is also installed. With the exception of the adaptive damper control, all assistance and driving dynamics systems of the BMW M8 remain active.
As an alternative to the KW Variant 4 coilover suspension for the BMW M8 (F92) and BMW M8 Competition (F92), height-adjustable KW springs are also available. The springs allow a continuously adjustable lowering from 5 to 20 mm on the front axle and 5 to 15 mm on the rear axle of the BMW M8 (F92). The height-adjustable KW springs, also known as coil springs, are also available for the BMW M850i xDrive models in the BMW 8 Series Coupé (G14), BMW 8 Series Convertible (G15) and BMW 8 Series Gran Coupé (G16) versions.
Since these three BMW models have a different axle construction than the BMW M8, the height-adjustable KW springs on the BMW M850i xDrive Coupé (G14) allow for a continuously variable lowering of 10 - 25 mm on both axles. On the BMW M850i xDrive Cabriolet (G15), the apporved adjustment range is 15 - 30 mm on the front axle and 10 - 25 mm on the rear axle. The BMW M850i xDrive Gran Coupé (G16) has a high center of gravity ex works and can be continuously lowered by as much as 20 - 35 mm at the front and 30 - 45 mm at the rear axle thanks to the height-adjustable KW coil springs. Due to the easy installation of the springs with their height adjustment and the precisely fitting dust protection elements, KW coil springs are also ideal for leasing vehicles due to their quick retrofitting. When installing KW coil springs, all damper control systems remain active ex works.
