The HKS Yamaha Performance Damper is a chassis damper, not a suspension damper and not a steering damper. It is a Yamaha Motor product that HKS re-tunes for each vehicle, and it works by damping the micro-deformation of the body shell itself, what Yamaha terms chassis viscosity, so that handling stability and ride comfort improve together instead of trading against one another. HKS describes the result as reduced vibration with a subtle but noticeable gain in handling. The set comprises two dampers with red steel brackets and mounting hardware: one mounted transversely across the front chassis behind the bumper beam, ahead of the intercooler and radiator support, and one at the rear. This part number covers both the first generation ZC6 and ZN6 cars and the second generation ZN8 and ZD8 cars, so check the fitment table below for the exact year and chassis.
