Optimize Your Subaru WRX/STI's Handling with Whiteline HD Mounts

The Whiteline KBR21-24 Heavy Duty Rear Sway Bar Mounting Saddle Kit is specifically designed for performance-oriented Subaru WRX and STI models. If you're running a larger diameter or adjustable rear sway bar (24mm), the factory mounts are likely insufficient, leading to flex and reduced effectiveness. This kit replaces those stock components with ultra-strong, forged alloy mounts that provide the necessary support for maximum performance.

Why Upgrade to Whiteline KBR21-24 Mounts?

  • Superior Strength: Forged alloy construction ensures these mounts can handle the significant forces generated by performance sway bars.
  • Eliminate Sway Bar Flex: Prevents the twisting and distortion of stock mounts, ensuring your sway bar works efficiently to reduce body roll.
  • Enhanced Stability: Experience a more planted and stable feel during aggressive cornering and spirited driving.
  • Direct Fitment: Engineered for a precise fit on the specified Subaru models, making installation straightforward.
  • Improved Responsiveness: Achieve sharper steering response and a more connected driving experience by eliminating unwanted flex.

Vehicle Fitment:

This heavy-duty mount kit is designed for:

  • 2002-2007 Subaru WRX (Sedan and Wagon)
  • 2004-2007 Subaru WRX STI
  • Also compatible with 1993-2007 Subaru Impreza Non-Turbo models and 2005-2006 Saab 9-2X.

Don't let weak mounting hardware hold back your Subaru's performance. Equip your WRX or STI with the Whiteline KBR21-24 Heavy Duty Rear Sway Bar Mount Kit for ultimate control and handling. Purchase yours today at GGCRACING!
