Construction & Design:

The Hipermax R coilovers are crafted with meticulous attention to detail and high-quality materials to ensure durability and consistent performance. The damping components utilize advanced SRF fluid technology, which provides rapid response to road inputs while maintaining smoothness over varying surfaces. The springs feature LVS technology to reduce vibrations transmitted to the chassis, enhancing comfort without compromising handling.

Full pillow ball upper mounts replace traditional rubber bushings, delivering precise steering feedback and reducing deflection during aggressive cornering. The coilover assembly incorporates helper springs and specialized retainers to maintain spring alignment and prevent coil bind, ensuring reliable operation under demanding conditions. The design improvements for the 2025 season include revised damping force, bumper rubber lengths, and front outer fastening structure, all aimed at refining handling and ride quality.

Installation & Fitment:

The HKS Hipermax R Coilovers are designed as a direct bolt-on replacement for the factory suspension components on Subaru BRZ models from 2008 through 2021 and Toyota GR86 models from 2010 through 2021. Installation requires no major modifications, making it suitable for enthusiasts seeking a professional-grade suspension upgrade without extensive fabrication.

It is important to note that these coilovers are optimized for circuit driving and feature settings that may feel firmer on public roads. The included full-length adjustable front stabilizer link should be used in conjunction with the height-adjustable suspension to maintain proper geometry and handling balance. While the coilovers can be overhauled for maintenance, specification changes or re-tuning services are not offered.
