For all models of the Porsche 911, including all air-cooled Porsche 911 as well as other Porsche vehicles such as Cayman, Cayenne or Macan, KW automotive offers a broad delivery program in height and damper characteristics adjustable coilover suspension kits. With its three-way adjustable KW shocks, the KW Variant 4 kit gives the current Porsche 911 (992 generation) an additional plus in driving dynamics combined with sporty rolling comfort. In fast narrow curves, demanding ride maneuvers with rapid load changes or on fast highway sections with transverse joints, the Porsche remains easy to handle with its straight-line stability. On undulating tarmac, the KW Variant 4 coilover suspension, which can be adjusted separately in the low-speed compression stage, high-speed compression stage and low-speed rebound stage, dampens harmoniously and prevents unsteady handling. Occurring pitch and roll movements of the body structure are significantly reduced. The KW coilover suspension can also be installed in all Porsche 911s of the 992 series with a front-axle lift system, which means that speed bumps or steep garage entrances are no obstacle despite the continuously adjustable lowering of 20 to 35 millimeters.
KW multi-valve technology provides enhanced driving dynamics and ride comfort immediately
The three-way valve technology of the KW coilover Variant 4 is based on current KW racing applications. “Relying on a three-way adjustable valve technology for coilover suspension kits gives us completely new possibilities in suspension design,” says KW Brand Manager Jonas Ehrmann. For example, in Porsche customer sport, KW racing applications are used in the 718 Cayman GT4 Clubsport, 911 GT2 RS Clubsport and 911 GT3 R. The adjustable compression damping influences the dipping speed of the damper piston rod to a certain degree. The compression damping also influences body pitching and rolling movements as well as turn-in behavior. If the compression damping is increased, the piston rod dips more slowly. This means that the vehicle acts more directly during steering movements. Turn-in behavior becomes more precise the tighter the compression damping is tuned. If the valves are opened, the compression damping is reduced, and the body immerges faster.
When adjusting the V4 further to your own driving style, you can separate the low-speed compression stage valve for slow piston rod movements, such as those that occur during steering and chassis rolling movements, and for fast damping speeds, such as those that occur during heavy compression due to bumps in the road, you adjust the high-speed compression stage valve,” Jonas Ehrmann explains further. The adjustable low-speed rebound stage has a direct influence on the operating speed when the piston rod rebounds. It controls how quickly the suspension spring relaxes back to its initial position. In a manner of speaking, the diameters of the rebound valves are opened for a more comfortable ride and closed for a firmer setup. “With our three-way adjustable dampers, this gives us much more flexibility to provide all Porsche 911 drivers with the best possible compromise between sporty driving dynamics and ride comfort on the road. The scope of delivery also always includes adjustment instructions that explain how the preset Sport+ basic setting can be changed to a comfort-oriented Street basic setting using the adjustment wheel, which can be operated without tools.” The parts certificate included in the scope of delivery allows stepless lowering from 20 to 35 millimeters on the front axle and from 15 to 35 millimeters on the rear axle. On the Turbo and Turbo-S models, a lowering of between 20 and 35 millimeters can be set on both axles with the suspension. But the main focus of the KW Variant 4 coilover suspension kit is to improve the ride quality and driving dynamics of the Porsche 911.
