The HKS Hipermax S Coilovers for Lexus GS (2012 and newer) and RC (2015 and newer) are high-performance suspension components designed to enhance ride quality and handling. This full kit, part number 80300-AT005, integrates the advanced damping force technology developed over nine years, evolving from the original MAXIV GT Series. The Hipermax S series combines durability, aesthetic appeal, and improved damping characteristics to deliver an optimal balance of comfort and performance. Constructed with high-quality materials, these coilovers feature spring rates of 78 N/mm (8.0 kgf/mm) at the front and 98 N/mm (10.0 kgf/mm) at the rear, ensuring precise control and stability during spirited driving or daily use. The series represents the culmination of HKS's suspension innovation, offering the best ride quality in the company's history.

Designed specifically for the Lexus GS from 2012 onward and the RC from 2015 onward, these coilovers are a direct replacement for the factory suspension, providing adjustable ride height and damping settings for tailored performance. They are suitable for street and track applications, allowing enthusiasts to optimize handling and stance. Installation is a bolt-on process, compatible with the vehicle's existing mounting points without requiring extensive modifications. The kit includes the coilover units and necessary hardware for installation. These coilovers are ideal for drivers seeking improved cornering, reduced body roll, and a more responsive driving experience, whether for daily driving, spirited canyon runs, or track days.
