The Z/28 is the first high-volume production road car to employ racing-derived DSSV® (Dynamic Suspensions Spool Valve) damper technology from Multimatic. The dampers rely upon a pair of self-piloted spool valves to control fluid through tuned port shapes rather than conventional deflected disc dampers. The design of the inverted-monotube front strut and aluminum-body monotube rear hydraulic dampers offers maximum response, stiffness and tuning optimized for the track, with the highest level of damper predictability, accuracy and repeatability. The unique dampers are the center of a comprehensive suspension package that also includes higher-rate coil springs, smaller-diameter solid stabilizer bars, and higher-rate suspension bushings. The dampers are matched with optimized stiff spring rates and stabilizer bars in both the front and rear to reduce body movement in hard cornering and acceleration. Also included in the package are front ride and handling links, rear upper control arms, rear trailing links, and toe links, which have upgraded stiffer bushings designed to reduce cornering compliance and increase durability on the track.
