Upgrade the handling and stance of your 2008–2014 Subaru Impreza WRX STI with the FIVE8 SS Sport coilover system. Designed for drivers who want precise ride height control and improved chassis response, this setup enhances the performance of the GR/GV STI platform while maintaining everyday drivability.

The STI chassis is built around a proven AWD system with aggressive handling characteristics, making it ideal for suspension tuning. FIVE8 SS coilovers help reduce body roll, improve cornering stability, and deliver a more planted and predictable driving experience compared to factory suspension components. With full ride height adjustability, you can fine tune both performance and stance to match your driving style.

Each kit is engineered with durability and consistent performance in mind. The mono-tube damper design promotes stable damping characteristics and improved heat management under demanding conditions. Electroplated carbon steel shock bodies help resist corrosion, while CNC-machined aluminum pistons and high strength springs ensure reliable suspension behavior over time.

For drivers searching for dependable STI coilovers, the FIVE8 SS Sport kit delivers adjustable ride height, solid construction, and improved suspension control for daily driving and performance builds.
