From Chevrolet Press: For the 2004 model year, commemorative editions for each Chevrolet Corvette model are available so enthusiasts can celebrate the racing success of the Chevy flagship.
Also, the top-of-the-line Corvette Z06 - already hailed by enthusiast magazines as the best combination of performance, comfort and value in the automotive world - gets even better for 2004 with revised shock valving based on testing at the legendary Nürburgring race track in Germany.
Corvette has remained relevant because it continued to embrace new designs and technologies such as those featured on the current line: Magnetic Selective Ride Control, Goodyear EMT "run-flat" tires (coupe and convertible), active handling and a rear transaxle.
The suspensions of the 2004 Corvette coupe and convertible continue to feature Magnetic Selective Ride Control, which debuted in 2003. It uses a revolutionary damper design that controls wheel and body motion with magneto-rheological fluid in the shocks. By controlling the current to an electromagnetic coil inside the piston of the damper, the MR fluid's consistency can be changed, resulting in continuously variable real-time damping. As a result, drivers feel a greater sense of security, a quieter, flatter ride and more precise, responsive handling, particularly during sudden, high-speed maneuvers.
The system isolates and smoothes the action of each tire, resulting in less bouncing, vibration and noise. On bumpy or slick surfaces, the system integrates with traction control to assure maximum stability. It also works with ABS to keep the vehicle balanced and poised. It is the only system without electro-mechanical values and no small moving parts. It consists of MR fluid-based, monotube shock absorbers, a sensor set and on-board controller.
