From the Holden Special Vehicles website: "Unlike other suspension systems, MRC is a semi-active suspension technology with no electro-mechanical valves and no small moving parts, which provides for durability and reliability. As a result, drivers can also expect to benefit from increased performance, safety, comfort and balance, for positive stopping power. At the heart of MRC is a central controlling unit that updates each damper every 1,000th of a second to the slightest change in road condition or driving style. The MRC based semi-active suspension system consists of magneto-rheological (MR) fluid-based monotube struts, monotube shock absorbers, a position sensor set and an onboard controller.
This MR fluid is a suspension of magnetically ‘soft’ particles that exhibit a random pattern when there is no current being applied to the system. In this state, the fluid behaves much like normal shock absorber fluid.
However, as the current is increased to the damper, the resultant magnetic field aligns the soft particles into fibrous structures, eventually changing the MR fluid to a near plastic state as the input current reaches its maximum value."
Hopes are high that the MRC suspension be an option, as many people prefer a coil-over setup for more adjustability.
