Subaru Performance Subframe Bushing Kits

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.

KSB750 is designed to lock the rear subframe which allows for more precise alignment of the rear wheels and limits the amount of rear subframe movement under cornering loads which can result in poor dynamic alignment settings. The hardware can easily be installed and removed between motorsport activities. The kit will increase rear NVH as it effectively locks out the rear subframe bushings. It is designed for motorsport use only and should not be used for extended periods as it may lead to premature chassis wear.

Not your typical remove and replace bushing kit but simple installation means great for the DIYer’s. Designed to work with the original bushing and eliminate over compliance or better known in motorsport as ‘lost motion’ of the rear crossmember. This Whiteline kit dramatically reduces rear cross member misalignment and movement which allows a more positive feel from the rear end during cornering.
