BMW's rear subframe is mounted on soft rubber 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.. Reduces initial torque loss and delivers greater power transfer to the wheels for crisper gear shifts and improved throttle response. Eliminates annoying clunks and vibrations caused by worn factory components; restoring a tight, solid feel to your suspension. Engineered in Australia and trusted worldwide; upgrade with confidence knowing Whiteline stands behind every product. Unlock noticeably improved handling and cornering grip that transforms your driving experience. Backed by Whiteline's Limited Lifetime warranty for lasting peace of mind.
