3WR
The MCS 3WR is a triple adjustable remote reservoir damper engineered for drivers and vehicles operating at the highest performance levels. Independent high speed compression, low speed compression, and rebound adjustment provide complete control over damper behavior across the full range of shaft velocities.
As grip levels rise and margins shrink, the 3WR allows precise separation of impact compliance and platform control, enabling the car to remain composed over curbing while maintaining stability under braking, acceleration, and sustained cornering. The remote reservoir architecture delivers increased fluid capacity and thermal stability for consistent performance under extreme loads.
Built as a long term solution for advanced track use and competition, the 3WR provides the depth of tuning required as the car, setup, and driver continue to evolve.
Comprehensive. Precise. Designed for peak performance development.
Technical Features
Application specific valving covers a wide range of spring rates and eliminates the need to constantly revalve every time you want to increase or decrease your spring rate. MCS has engineered its adjustment mechanisms so each click can be felt, but never feels like you’ve gone too far.
18 Clicks of High Speed Compression Adjustment
Compression adjustment allows the driver to progressively add platform support, improving use of the tire’s mechanical contact patch as grip and speed increase. This results in better control under braking, improved mid corner stability, and more consistent lap times.
Compression damping forces are managed by a large blow off valve located directly on the reservoir piston. This approach delivers precise, repeatable control across the full adjustment range and avoids the narrow effective window common to needle valve systems, where changes quickly lose influence as flow increases.Rebound adjustment allows the driver to progressively increase spring control and fine tune overall chassis balance as grip, speed, and commitment rise. Proper rebound control improves how the car settles after inputs, maintains tire contact through transitions, and delivers consistent behavior corner to corner.
10 Clicks of Low Speed Compression Adjustment
Low speed compression adjustment allows the driver to directly influence vehicle pitch and roll during low velocity damper movements, typically in the 0 to 4 inches per second range. This control is critical for tuning braking stability, corner entry response, and mid corner balance.
Low speed compression damping forces are regulated through precision orifices located in the compression piston assembly within the reservoir head. This architecture provides consistent, repeatable adjustment with clear response per click, enabling fine control of chassis behavior without compromising compliance.
18 Clicks of Rebound Adjustment
Rebound adjustment allows the driver to progressively increase spring control and fine tune overall chassis balance as grip, speed, and commitment rise. Proper rebound control improves how the car settles after inputs, maintains tire contact through transitions, and delivers consistent behavior corner to corner.
Rebound damping forces are regulated through precisely sized orifices at the main piston assembly within the damper body. This hydraulic architecture provides a wide, usable operating range with consistent response per click, reduces the need for frequent revalving, and maintains repeatable damping performance over extended use without degradation.
Gas Pressure Adjustment
Each remote reservoir is equipped with a Schrader valve, allowing direct adjustment of the nitrogen gas pressure. This adds a powerful tuning tool that lets the driver increase or decrease overall damper support without changing valving.
Reservoir pressure is adjustable from 100 to 275 PSI, providing flexibility to support higher cornering loads in high grip conditions or to allow increased weight transfer when maximizing traction on lower grip surfaces. This adjustment expands the usable operating window and allows the damper to be tuned as vehicle demands and driving style evolve.
<0.5%
Thousands of systems in service worldwide with less than a half percent reported failure rate. Built for reliability first, because confidence starts with consistency.
3.5x
Up to 3.5 times the service life of typical aftermarket coilover systems, delivering more miles, more track time, and fewer rebuild cycles.
0.3 sec
Per corner, per lap. Typical gain versus competing motorsport damper systems, measured in corner segments. Bigger gains when upgrading from entry level aftermarket suspension.
