The third-generation Magnetic Selective Ride Control dampers are standard on Z06. They can be adjusted for touring comfort or maximum track performance via the standard Driver Mode Selector.
Third-generation MagneRide (Magnetorheological Fluid-based Vehicle Suspension System)
The MR fluid is a suspension of magnetically soft (easily, but temporarily magnetised) particles in a synthetic hydrocarbon base fluid.
Semi-active suspension using adaptive damping can overcome the limitations of passive dampers, providing much of the benefit of a fully active system without incurring the high cost and energy consumption penalties.
