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.
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.
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.
When selecting suspension upgrades, consider your driving style and goals—whether you prioritize daily comfort, spirited street driving, or track performance. Our collection at Subimods offers a range of options from coilovers to sway bars and bushings, all engineered specifically for your STI’s chassis and suspension layout. Explore our selection to find the perfect balance of performance and reliability for your build.
