Two-Step Rebound Valve with Adjustable KW TVR-A Rebound Stage Damping Technology
The rebound stage damping is precisely tuned to the respective vehicle on our in-house drive dynamics test facility, with the setting fixed in the mid-range. Individual customization can be achieved in 16 precise click positions, allowing you to choose between more comfort or more body control. The two-step patented TVR-A technology allows the damper oil to flow through an adjustable, conical low-speed valve during slow piston speeds, while during higher piston speeds the main rebound stage valve opens to handle the flow of large volumes of oil. This provides a major improvement in ride comfort without influencing the high-speed in the safety-relevant zone.

Two-Step Compression Stage Valve with Low and High-Speed KW TVCLH-A Adjustment Technology
This is the high-end motor sports technology for the most demanding street and track performance customers. Two separate valves and a two-way adjustable compression stage valve allow separate compression damping changes in the low and high-speed range. The adjustments are made via two adjustment dials with click increments that feature 16 settings (with 15 clicks) in the high-speed valve housing and 7 settings (with 6 clicks) in the low-speed housing. During tuning at the KW drive dynamics test facility, the groundbreaking V4 coilover suspension is tuned to a mid-level basic setting for the best road performance with an additional recommended setting for occasional track day use. The 3A Clubsport coilover suspension is tuned to a mid-level factory setting especially for track day use, with an additional recommended setting for the drive to the race track. Starting from the factory setting, the damping can be set firmer or softer for low and high-speed. 

External Reservoir
The use of KW reservoirs provides additional volume for additional oil and additional cooling capacity for extremely high-performance setups. The reservoir is filled with low gas pressure and can be fitted anywhere and accommodates the adjustable compression stage valve to provide the damper with more working space.
