Whiteline Rear Differential Mount Inserts for Subaru WRX & STi

Enhance the traction and handling of your Subaru WRX and STi (2008-2011 models) with the Whiteline Rear Differential Mount Inserts. This kit is specifically designed to work within the factory differential bushing, effectively eliminating 'lost motion' and reducing excessive movement of the rear crossmember. By minimizing this misalignment and movement, the kit ensures more consistent power delivery to the wheels, significantly reducing wheel hop during acceleration and improving overall stability during cornering.

Key Benefits:

  • Reduced Wheel Hop: Dramatically decreases wheel hop under hard acceleration.
  • Improved Traction: Ensures more consistent and effective power transfer to the rear wheels.
  • Enhanced Stability: Provides a more planted feel during cornering and braking.
  • Positive Drivetrain Feel: Delivers a more direct connection between the engine and wheels.
  • Simple Installation: Designed as inserts for the OEM bushing, making installation easier for DIYers.

This Whiteline kit is an excellent upgrade for Subaru owners who demand more from their drivetrain, especially those participating in track days, autocross, or simply seeking a more engaging driving experience. The reduction in differential movement leads to a more predictable and controllable rear end, allowing you to confidently apply power out of corners. Installation is straightforward, requiring no complex procedures, making it an accessible performance enhancement.

Maximize your Subaru's potential with Whiteline performance components from GGCRACING.
