    SKU: BSR49XZ Benefit Note: Engineered to 'Activate More Grip', sway bars are principally designed to reduce body roll or sway. By reducing body roll, lateral loads are spread more evenly across the tyres thereby increasing cornering grip and improving outright performance. This Whiteline 22mm 3 point adjustable sway bar = more grip = better handling = outright performance - it's the best dollar for dollar handling improvement you can make to your vehicle. In fact, benefits extend to improvements in handling, safety and tyre wear without affecting ride quality or comfort.

    SKU: KDT937 Benefit Note:
    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.
