MCS 4WR
The MCS 4WR damper is a 4-way adjustable suspension system with an external reservoir, offering fully independent adjustments for high-speed compression, low-speed compression, high-speed rebound, and low-speed rebound damping. Gas pressure is also finely adjustable via a Schrader valve, providing advanced tuning capability for professional motorsport applications.
The high-speed and low-speed compression adjusters are conveniently located on the remote reservoir head, while rebound adjustments are made via a dedicated single knob. High-speed damping is precisely controlled by blow-off valves, while low-speed damping is managed through precision-engineered orifices, delivering accurate hydraulic control and an extensive tuning capability.
Reservoir pressure can be set between 6 and 18 bar, allowing drivers to increase chassis support during high-speed cornering or fine-tune weight transfer for enhanced traction in low-grip conditions.
The monotube construction ensures exceptional stability, with increased oil capacity and superior heat dissipation compared to twin-tube dampers. Large-diameter shafts provide low-friction side-load support, while a divider piston prevents cavitation, guaranteeing consistent damping performance. This advanced design allows for precise and repeatable adjustment and effective management of high-speed forces, delivering maximum mechanical grip and driver confidence
Knob in “down” position controls high speed rebound damping forces.
Knob in “up” position low speed rebound damping forces.
Adjustability
The MCS 4WR damper is a 4-way adjustable suspension system offering 18 clicks of high-speed compression, 10 clicks of low-speed compression, 18 clicks of high-speed rebound, and 10 clicks of low-speed rebound adjustment. Its user-defined valving is precisely tailored to the vehicle’s preparation level, incorporating valuable insights and data gathered during development.
Compared to the MCS 2WR and 3WR systems, the 4WR provides a more refined and clearly defined operating range, allowing for finer adjustments and greater control over the shape and progression of the damping curve, giving drivers the tools needed to achieve optimal handling response and grip in even the most demanding conditions.
18 Clicks of High Speed Compression Adjustment
On the MCS 4WR damper, high-speed compression damping can be precisely adjusted with 18 distinct settings. This enables drivers to increase platform support by fine-tuning damping forces during high-speed shaft movements. Optimising this behaviour allows the suspension to make better use of the tyre’s mechanical contact patch, improving grip, stability.
10 Clicks of Low Speed Compression Adjustment
Low-speed compression damping on the MCS 4WR damper is easily adjusted with 10 precise clicks, allowing drivers to finely tune vehicle pitch and roll behaviour during low-speed shaft movements. This level of control directly influences how quickly a tyre or axle is loaded, improving balance, feedback, and driver confidence under braking, turn-in, and weight transfer conditions.
18 Clicks of High Speed Rebound Adjustment
On the MCS 4WR damper, high-speed rebound damping can be precisely tuned to manage stored spring energy during high-speed rebound movements. This adjustment helps the chassis maintain a stable platform over bumps and kerbs during rebound motion, improving vehicle control, grip, and consistency in demanding motorsport conditions.
10 Clicks of Low Speed Rebound Adjustment
The MCS 4WR damper allows precise adjustment of low-speed rebound damping with 10 defined settings. This tuning capability enables drivers to manipulate vehicle pitch and roll during the rebound travel in low-speed shaft movements. Adjusting low-speed rebound directly influences how quickly a tyre or axle unloads, helping to maintain chassis balance, traction, and stability through transitions and corner exits.
Gas Pressure Adjustment
Each remote reservoir on the MCS 4WR damper is equipped with a Schrader valve, offering a powerful tuning tool that allows precise adjustment of nitrogen gas pressure within the damper. By increasing or decreasing reservoir pressure, drivers can fine-tune overall chassis support, adapting suspension response to road conditions and driving style.
Reservoir pressure can be set between 6 and 18 bar, providing additional platform support during high-speed cornering where heavy loads are generated, or allowing greater weight transfer to improve traction and grip in low-grip scenarios.
