HKS Hipermax S Front Pillow Ball Coilover Full Kit with Canceller - Subaru WRX S4 (VBH) 2021+

This kit is supplied with an HKS suspension error canceller so the factory electronically controlled damper circuit does not throw a fault once the original units are removed, and it uses pillow-ball front upper mounts with reinforced rubber at the rear. The damper is an inverted monotube at the front and an upright monotube at the rear, each with 30 steps of damping force adjustment. Springs are 7.0 kgf/mm front and 6.0 kgf/mm rear with a rear helper spring, and full-length shock body adjustment spans stock ride height to 52 mm lower in front and 64 mm lower at the rear. The VBH WRX S4 is a Japanese domestic market chassis, and HKS does not offer a factory spring rate change on this part number.
