Description

Take your vehicle's handling to the next level with the PERRIN Performance 16mm rear adjustable sway bar. Upgrading the rear sway bar is the easiest way to improve vehicle handling — sway bars increase roll resistance and let you tune the vehicle's balance. In general, a larger rear sway bar increases oversteer; upgrade front and rear together to reduce body roll.

  • Fits: 2008-2021 Subaru WRX, 2008-2021 Subaru WRX STI, 2013-2016 Scion FR-S, 2013-2023 Subaru BRZ, 2017-2021 Toyota 86, 2022-2023 Toyota GR86 (perrin.com product page; Import Image Racing; MAPerformance — note: dealer sources conflict on the BRZ/86/GR86 upper years, 2021 vs 2023 vs 2026)
  • PERRIN part number: PSP-SUS-229
  • 16mm diameter rear sway bar, adjustable
