During the Essen Motor Show 2023, KW automotive unveiled its next generation of motorsport dampers designed for hybrid prototype sports cars and formula cars. These new KW V6 Formula Racing CPR Heave dampers and KW V5 Formula Racing CPR Roll dampers will be used for the first time in the Lamborghini SC63 LMDh (Le Mans Daytona hybrid).
As the official technical partner of Lamborghini Squadra Corse – the motorsport department of the Italian car manufacturer – we from KW automotive are making the next big step and entering the top class of the FIA World Endurance Championship with our KW suspension technology.
Through the partnership with Lamborghini Squadra Corse, we are also equipping LMDh racing cars with our KW Solid Piston dampers for the first time in the world’s premier WEC and IMSA sportscar championship hypercar classes.
Following our meticulous fine-tuning on the KW 7-post test rig, the Lamborghini SC63 underwent a successful test phase in recent months as we collaborated closely with our technical partner, Lamborghini Squadra Corse, on the racetracks.
Equipping and supporting the inaugural Lamborghini Squadra Corse LMDh prototype with our suspension technology for the 24 Hours of Le Mans, 24 Hours of Daytona, 12 Hours of Sebring and the entire WEC Endurance Championship is a source of immense pride for us all from KW.
Formula Racing Series, the next generation of KW Solid Piston dampers
The new innovative KW Formula series, based on through-rod technology, offers a comprehensive range of CPR heave, CPR roll and CPR rad dampers tailored for prototype sports cars, including Le Mans hypercars, LMDh hypercars and formula cars.
Our Formula Racing solid piston dampers operate at a high frequency over a short stroke. What is new is the utilization of a continuous piston rod for the V6 Formula Racing CPR Heave damper and V5 Formula Racing CPR Roll damper employed in the SC63.
With their continuous piston rod design, solid piston dampers possess the distinct advantage of nullifying gas expansion force and minimizing hysteresis.
As a result, temperature fluctuations within the damper do not exert any influence on ride height alterations in the racing car. This is a particularly big advantage for vehicles with a lot of downforce, such as the SC63.
The V6 CPR Heave damper is five-way adjustable. The low-speed and high-speed parameters of the compression and rebound valves can be adjusted.
The dampers also have an adjustable blow-off valve in the compression direction. In defined steps, the spring preload of the coil spring can be increased or decreased using a click mechanism.
The V5 CPR Roll damper is adjustable in three ways. The valves function uniformly in the low-speed, high-speed and blow-off directions, both in compression and rebound.
The KW Formula Racing dampers utilized in the Lamborghini SC63 are optimized for weight and feature a slim design.
Our unwavering commitment to research, development and production at our headquarters has solidified our position as a trusted partner in the automotive industry’s customer sports programs.
Alongside the Lamborghini SC63 by 2024, about one third of the GT3 race cars in the FIA World Endurance Championship and the IMSA WeatherTech Sportscar Championship will be racing with KW Racing dampers.
With its notably concise decision-making processes and the capability to produce customized products down to individual builds, an increasing number of OE customers are establishing partnerships with this family-owned business from Fichtenberg for specific motorsport projects and special models.
