New KW Suspension Solution For A Mercedes-Benz C63 AMG

Recently released Mercedes-Benz C63 AMG offers 476 hp at the rear axle, the C63 S AMG mobilizes even 510 hp, powering the rear wheels. With this amount of power, for some owners, the handling aspect of such vehicles needs to be further upgraded and ready for track use. Finally available, the KW coilover suspension Variant 3 made of stainless steel is available for the sporty AMG four-door model. Completely adjustable in compression and damping, allowing the vehicle to be lowered up to to 35 mm, while giving the C63 S AMG and C63 AMG a significant increase in driving dynamics. The adaptive KW DDC plug&play coilover kits and the height-adjustable KW coilover springs are already being developed.


The KW coilover suspensions Variant 3 made of stainless steel gives the new C63 AMG and C63 S AMG (W205) sedan the ideal balance of everyday practicality, driving dynamics and individual setting options in comfort and sportiness. “Nobody has to accept a compromise at his AMG anymore with the KW dampers that are independently adjustable in compression and rebound damping”, says KW Product Manager Johannes Wacker. The KW coilovers Variant 3 allow adapting the C63 to the personal driving style. It does not matter whether the AMG is constantly driven at its limits of driving dynamics or if it is used mainly as sporty touring sedan. “Those who drive their AMG with a KW coilover suspension Variant 3 installed, benefit from our experience with the equipment of different AMG Black Series models.”


Driving dynamics is a matter of adjustment
“As all the drivers experience their AMG completely different, they can adapt the sports car individually to their driving style with our coilover kits”, says KW Product Manager Johannes Wacker about the advantages of a KW Variant 3 kit. The KW bottom valve that is adjustable in twelve clicks in the low speed range of the compression damping, allows furthering increasing the performance of the AMG. So a higher compression damping at the front axle enables a more direct steering and on the rear axle, higher compression damping forces act against oversteering.

Due to the declining-balance valve assembly of the KW coilover suspension, the deflection behavior during sudden driving over bumps is not affected. If the compression forces are decreased by using the integrated adjustment wheel at the lower piston end of the stainless steel housing on the rear axle, the rear will steer more. With the adjustable rebound damping, it can directly be taken influence on the handling characteristics and ride comfort of the new AMG sedan. The 16-step click adjustment for the rebound damping allows to increase or decrease the rebound damping forces. A higher rebound increases the handling and road holding; while the comfort when driving slowly is improved with a lowered rebound force.

The continuous lowering can be adjusted via the dirt-resistant trapezoid thread directly on the stainless steel strut. So the C63 AMG can be lowered within the tested adjustment range from 0 to 30 mm. On the drive axle, the adjustment of the vehicle height is made directly on the rear-axle height adjustment within the range of 5 to 35 mm. The adaptive KW DDC plug&play coilover kit and the height-adjustable KW coilover springs for the new C63 AMG are already in development.
