Pillow-ball front upper mounts tie the strut top directly to the body for a sharper steering response, with reinforced rubber mounts retained at the rear. The Hipermax S damper is an inverted monotube at the front and an upright monotube at the rear, each with 30 steps of damping force adjustment. HKS sets a matched 5.0 kgf/mm front and rear spring pairing with a rear helper spring, and full-length shock body adjustment covers stock ride height down to 46 mm lower in front and 40 mm lower at the rear. Dual PVS valving, the WR Needle soft-range circuit, Advanced Bump Rubber and PNE corrosion-resistant plating are standard.
