KW V4 coilovers are a combination of our innovative, race proven technology, as well as decades of experience tuning high end sports cars, super sedans and exotics such as the Audi R8, Audi RS6, BMW M5, Lamborghini Aventador LP 750-4 SV, Dodge Charger SRT Hellcat, Mercedes AMG GT and more. In addition to the individually adjustable ride height the KW V4 coilover kit allows an independent adjustment of the rebound damping as well as the low-speed and high-speed compression damping. Each KW V4 coilover kit is delivered with a vehicle-specific comfort setting and with the integrated adjustment controls the damping characteristics can be set quickly and intuitively transformed to an optimized performance setup.
Specifically Engineered Setup Vehicle specific with independently adjustable rebound, high and low speed compression. The 3-way adjustable high-performance dampers in the KW V4 coilover kits feature independent adjustment of the rebound damping utilizing patented TVR-A technology, as well as the low speed and high speed compression damping utilizing TVCLH-A technology. The KW V4 coilovers are based upon successful race technology utilized by multiple overall winners of the ADAC Zurich 24h Nürburgring race.The new KW V4 coilovers are exclusively developed for select high-performance vehicles, which benefit greatly from the KW suspension technology to improve their driving dynamics.
TVR-A Technology The two-stage, patented TVR-A (Twin Valve Rebound - Adjustable) technology enables a small volume of oil to flow through an adjustable, conically shaped, low-speed bypass during low damper speeds, while in the case of higher damper speeds, the main rebound stage valve opens allowing a larger volume of oil to flow. This provides a big improvement in terms of ride comfort without influencing the safety-relevant high-speed range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVCLH-A Technology With 6 precise clicks in low-speed and 14 precise clicks in high-speed range of the compression damping, the cross-sections in the V4 valves are decreased or increased, in order to achieve either more or less compression damping. The TVCLH-A (Twin Valve Compression Low High - Adjustable) technology has an engineered blow-off characteristic providing a large cross-section that allows substantial low-speed forces to provide optimum support of the vehicle body without unsettling the body in the case of sudden high damper stimulation induced by the wheels, like driving over apex curbing. The separate low and high-speed settings are always supplied with an additional rebound setting utilizing TVR-A technology for a truly independent 3-way damper setup.
