2015-18 Subaru STI Front & Rear Sway Bar Kit
Sway-A-Way’s 2015-2018 Subaru STI Front & Rear Sway Bar Kit is designed to replace both factory sway bars with adjustable larger diameter sway bars. Stock, the 2015+ Subaru STI kits come equipped with a 24mm front and 20mm rear sway bar. Sway-A-Way’s Front & Rear sway bar kit includes a 25.4mm front sway bar with 2 holes of adjustment and a 22mm or 24mm rear sway bar with 3 holes of adjustability. This complete sway bar kit provides a large increase in stiffness that will remove body roll for better overall handling and grip. Because of the larger relative stiffness increase in the rear sway bar, Sway-A-Way’s front and rear kit remove factory understeer giving the car a more neutral to oversteer feel. Please refer to the charts below for the relative stiffness increases.

CNC Bent to Factory Profile
Sway-A-Way uses in-house 3D scanning equipment and a CNC bender to precisely match the factory sway bar profile. This allows Sway-A-Way’s 2015+ SubarSTI front sway bar to retain access to motor mounts.
Precision Forged Ends
Through processes mastered over the last 30+ years, Sway-A-Way uses induction heating, presses, CNC plasma cutting, and custom tooling to craft forged ends. This combination of CNC bending and forged ends results in a sway bar that is both strong, accurate and ready for the track.
Sway-A-Way’s 2015-2017 Subaru STI Rear Sway Bar uses welded on bushing collars to prevent lateral sway bar movement, keeping the sway bar centered.
Powder Coated for Corrosion Resistance
Sway-A-Way sway bars all receive a red powder coat for lasting corrosion resistance.
Polyurethane Bushings & Grease
Included with every sway bar are two polyurethane bushings cast specifically for the stock bushing bracket and Energy Suspension Formula 5 Polyurethane Grease. These bushings & grease are sourced directly from Energy Suspension, the leader in performance polyurethane products.
