Pillow-ball front upper mounts replace the rubber items used on the standard kit, removing deflection at the strut top for a more precise steering response, while the rear keeps reinforced rubber mounts. The damper is an inverted monotube in front and an upright monotube at the rear with 30 steps of damping force adjustment, and the left rear is adjusted remotely by cable. Springs are 6.0 kgf/mm front and 5.0 kgf/mm rear with a rear helper spring, and full-length shock body adjustment reaches 65 mm of front drop and 12 mm to 85 mm of rear drop against stock ride height. This pillow-ball part number is the one HKS lists for the turbocharged SR20DET S15 as well as the naturally aspirated cars.
