Subaru designed the pitch stop mount to assist in controlling the engine and drivetrain forward and aft twisting motion. The pitch stop is inherently soft due to the plastic body and high compliance rubber bushing design and was built for comfort and not responsiveness or feel. Whiteline's Billet 6061-T6 aluminium pitch stop mounting is built to handle the demands of high torque and power output engines by limiting the amount of movement the engine and drivetrain will place upon the pitch stop. Utilising low compliance bushing technology this eliminates the slop, twisting and shudder found in the OEM rubber bushings allowing for a faster, positive, responsive feel of power delivery on and off the throttle.

Whiteline's differential bushing solutions ensure pinion angles are maintained while delivering an improved gear shift resulting in reduced initial torque loss and greater power transfer to the wheels.

Whiteline's differential insert bushings work within the voids of the original factory bushing to ensure pinion angles are maintained while delivering an improved gear shift resulting in reduced initial torque loss and greater power transfer to the wheels.

Heavily voided OEM rubber differential bushings allow a significant amount of shudder and wheel hop during hard throttle acceleration. Using Whiteline's low compliance polymer bushing technology to control the differential pinion movement this kit eliminates the ability for the differential to move on the bushings giving a crisp power delivery to the rear end without compromising driver feel.

Heavily voided OEM rubber differential bushings allow a significant amount of shudder and wheel hop during hard throttle acceleration. Using Whiteline's low compliance polymer bushing technology to control the differential pinion movement this insert kit positively locates the front and rear differential bushings restricting the ability for the differential to move around providing a more precise power delivery to the rear end without compromising NVH.
