Description

The HKS HIPERMAX S coilover system for the 2023–2025 Toyota GR Corolla is engineered to enhance ride comfort while preserving the excellent performance characteristics of the factory suspension. Designed for daily driving and spirited weekend use, HIPERMAX S delivers refined damping control, improved stability, and a balanced vehicle stance.

This system features a single-tube damper design with 30 levels of adjustable damping, allowing drivers to fine-tune ride quality for varying road conditions. HKS Dual PVS (Preload Valve System) and Wide Range Needle technology provide ideal damping force characteristics across a broad adjustment range while eliminating harshness in high-speed damping scenarios.

Ride height is optimized for both appearance and comfort, while rubber upper mounts, spring insulators, and rubber seats are included as standard equipment to ensure quiet operation and long-term durability. Finished with HKS PNE coating and filled with special oil, HIPERMAX S is built for reliability and performance.

Backed by a 3-year warranty and fully overhaulable, the HKS HIPERMAX S is an ideal suspension upgrade for GR Corolla owners seeking comfort, control, and long-term support.
