The Whiteline KDT937 rear subframe bushing kit replaces rubber voided mounts with low compliance polymer bushings. They lock the frame position and remove lateral walking with high grip tyres, and soft stand off buffers on the top and bottom allow slight vertical movement, which removes the rock solid noise, vibration and harshness feel.
Subaru's rear subframe is mounted on rubber-voided bushings which allows for a significant amount of compliance/movement in the frame during high cornering loads. Whiteline's low compliance polymer bushings eliminate this condition by positively locking in the frame position and removing the 'lateral walking' found when using high-grip tires. The polymer bushing design has soft 'stand-off' buffers on the top and bottom surfaces of the bushing to allow slight vertical bushing movement of the subframe to eliminate that 'rock-solid' NVH feel and cushion against minor bumps and allow solid positive location when high torque and power is applied.
