Construction & Design

The AST 5200 Series Coilovers are built with a focus on durability and precision. The main shock bodies are constructed from high-strength steel with a corrosion-resistant finish, ensuring longevity even in harsh conditions. The remote reservoirs are connected via high-quality braided steel lines, which provide reliable damping performance and heat dissipation. The adjustable components are CNC-machined for precise fitment and smooth operation, allowing for easy adjustments without tools.

The design incorporates a twin-tube construction with a monotube damper, providing a consistent damping response and improved heat management. The adjustable rebound and compression damping are engineered to deliver predictable handling characteristics, whether you're pushing your car on the track or enjoying spirited street driving. The coilovers are also designed to be compatible with factory mounting points, ensuring a straightforward installation process.

The coilovers are designed to fit directly into your Subaru WRX/STI's factory mounting points, with no need for cutting or drilling. For optimal performance, some minor alignment adjustments may be recommended after installation. No special tuning is required, but fine-tuning the damping settings can help you achieve your preferred ride and handling balance.
