PERRIN 08-21 WRX/STI & 13-25 BRZ/FR-S/86/GR86 Rear Sway Bar - 18mm

The PERRIN 18mm rear sway bar upgrades handling on 2008-2021 Subaru WRX/STI and 2013-2025 Subaru BRZ/Toyota 86/Scion FR-S/Toyota GR86 models. This adjustable bar reduces body roll during cornering for flatter turns and quicker response. Drivers gain precise control and confidence in spirited driving.

Key Features

  • 3-Way Adjustability: Choose soft medium or hard settings to dial in balance for daily driving autocross or track days without removing the bar.
  • 18mm Hollow DOM Steel: Thicker and stronger than OEM bars to resist flex and maintain shape under high cornering loads for consistent performance.
  • Polyurethane Bushings: Greasable design eliminates squeaks and provides smooth long-lasting operation far beyond rubber OEM bushings.
  • Bent Ends: Factory-style bends ensure proper endlink geometry and prevent interference with exhaust or suspension components.
  • Complete Hardware Kit: Includes zinc-plated brackets bolts and bushings for direct bolt-on installation with no fabrication needed.

Product Notes

  • Pair with front sway bar for balanced chassis setup and even more neutral handling.
  • Clean bar with mild soap and apply grease to bushings during service for peak performance.
  • Product weight is 12 lbs and ships in a 38 x 6 x 6 inch box via ground service.

Installation Notes

  • Professional installation recommended.
  • Bolt-on fit takes 1-2 hours with basic hand tools and jack stands.
  • Reuses factory endlinks and mounting points for simple swap over stock bar.
