Your 2015-2021 Subaru WRX STI suspension deserves better than factory compromise. The STI already handles well, but upgrading your WRX STI suspension unlocks the chassis potential that Subaru engineers had to dial back for daily driving comfort. Whether you're hitting the track or carving canyon roads, the right Subaru STI suspension setup transforms how your car feels and performs.

COBB Tuning rounds out the package with their proven lowering springs and anti-roll bars.
Your STI suspension upgrade covers more than just shocks and springs. Torque Solution provides solid engine and transmission mounts that reduce drivetrain movement, Super Pro bushings eliminate rubber flex points throughout the chassis, and Prothane polyurethane components last longer than factory rubber. Don't overlook supporting modifications like Perrin Performance's strut tower braces and ISC Suspension's adjustable dampers for serious track work.
The premium end includes Ohlins dampers for race-level adjustability, Bilstein's legendary reliability, and Tein's affordable performance options.
