Upgrading the suspension on your 2015-2021 Subaru STI is key to unlocking sharper handling, improved stability, and a more confident driving experience. Our collection offers precision-engineered coilovers, sway bars, bushings, and more, all designed to meet the demands of enthusiasts who want both daily comfort and track-ready performance.

How does upgrading coilovers improve your 2015-2021 STI’s handling?

Coilovers provide adjustable ride height and damping, allowing you to fine-tune your STI’s suspension setup for different driving conditions. By lowering the center of gravity and controlling body movement, coilovers enhance turn-in response and reduce body roll during aggressive cornering. This results in a more planted feel and better overall control on both street and track.

• Adjustable ride height for improved stance and handling
• Variable damping to balance comfort and performance
• Reduced body roll for sharper cornering
• Durable construction designed for Subaru STI specifications

What role do sway bars and bushings play in STI suspension upgrades?

Sway bars and bushings are critical for chassis stiffness and suspension precision. Upgraded sway bars reduce body lean by distributing weight more evenly during turns, which improves stability and grip. Performance bushings replace worn or soft factory components, providing more direct steering feedback and consistent suspension geometry under load.
