Whiteline 12+ Scion FR-S/Subaru BRZ Rear Diff-Mount in Cradle & Support Outrigger Insert Bushing

If you're looking to get a more direct feel from your drivetrain, these rear differential mount insert bushings from Whiteline are a solid option for your 2013-2020 Subaru BRZ or Scion FR-S. They work by inserting into your factory differential bushings, stiffening them up to reduce unwanted movement. This helps maintain proper pinion angles, which means less initial torque loss and a more immediate transfer of power to the wheels when you accelerate.

Whiteline builds these inserts with a specially bonded design for strength, and they feature internal grease reservoirs that self-lubricate to manage friction. The metal components are protected with plating and powder coating to resist corrosion, while the synthetic elastomer material is resistant to oil, grease, ozone, and weathering. They even come with a specific grease for extended life. These inserts are designed to work with your original factory bushings, making them a straightforward upgrade to improve drivetrain response.
