KW V4 Coilover Kit for W205 Mercedes-Benz C63 / C63 S Sedan with Electronic Dampers [3A725081]
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 w/ 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 volumn 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 provice 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 truely independent 3-way damper setup.
Continuous Ride Height Adjustment
With KW V4 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension with adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar.
The Benchmark for Coilovers
As with all KW coilovers their engineers develop vehicle specific damper and spring specifications which undergo comprehensive testing on the Nürburgring Nordschleife and in their KW 7-post Driving Dynamic Test Center. With a KW V4 coilover kit the driving experience is more dynamic and direct.
You are not buying a mass produced, generic coilover kit, a KW coilover has been developed specifically for your particular vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that has all developed in-house. With the KW V4 coilovers, rolling motion of the body will be reduced during compression giving you the benefit of more direct handling and confidence while driving.
KW’s Experience Means Your Driving Pleasure
For over 20 years, KW automotive has been the market leader and driving innovation as a manufacturer of individual suspension solutions for the road and in all types of motorsports. No matter where in the world, gearheads, automobile manufacturers and reputable tuners rely on our KW coilovers “Made in Germany”.

Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate.

Shipping Policy
-+
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
BP Pricing Difference
-+
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well.
For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
