Description
The HKS HIPERMAX S Coilover Kit provides a defined suspension configuration for controlling ride height and chassis movement. Application: Subaru Impreza WRX STI (GDB).
Design and operation
Spring rates establish the suspension’s load response, while damper settings control how quickly the suspension moves. Selecting the correct kit involves balancing usable suspension travel, tire clearance and the vehicle’s intended driving conditions.
