Product Details
HKS Hipermax S coilovers for the 2009-2024 Nissan GT-R (R35) are engineered for drivers who want genuine performance gains without giving up daily-driver comfort. Built around HKS's FLAT RIDE CONCEPT, the Hipermax S smooths out low-speed harshness while keeping the Nissan GT-R planted under hard cornering — delivering the refined, controlled ride quality that makes a coilover worth owning on the street.
30-level damping adjustment, a large-diameter monotube damper, Dual PVS, and DURA BOOTS give the Hipermax S its signature mix of long-life durability and tunability. Length-adjustable shock bodies let you lower the Nissan GT-R without pre-loading the spring, and every kit is backed by HKS's class-leading 3-year / 60,000 km warranty — validated over 60,000 km of real-world testing before it ever leaves Japan.
