Product Description

The HKS Hipermax R Coilovers are the flagship of HKS’s suspension evolution—born from decades of motorsport innovation and tuned for the modern enthusiast. With a goal of becoming the “Ultimate All-Rounder,” this system brings together the responsiveness of a race damper and the comfort of a luxury daily.

The 30-step damping force adjustability allows you to tune your ride for the street, the track, or anything in between. Match that with height adjustability and spherical bearing upper mounts, and you’ve got a suspension setup that’s as flexible as your driving style. Whether you’re aiming for tight control on twisty roads or a composed ride for city cruising, this kit delivers.

Built with mono-tube dampers, the system offers improved damping response, reduced fade, and better heat dissipation. The inclusion of SRF oil and LVS springs ensures consistent feel even under aggressive driving, while the PNE coating fights rust and keeps adjustments smooth year after year.

This setup doesn't just perform—it communicates. The road feel is sharper, the grip is more confident, and the adjustability gives you the freedom to evolve with your build or driving preferences. It's track-capable yet daily-drivable, aggressive when you want it, and composed when you need it.
