Powerflex PFR5-4616BLK Rear Lower Arm Inner Bush Upgrade for BMW E36, E46 and Z4 E85 E86 E89

Transform the rear-end feel of your BMW with this motorsport-grade inner pivot bush for the lower rear arm. The PFR5-4616BLK kit uses a 95A durometer polyurethane compound to control movement at the inboard mounting point, keeping geometry true under hard load and delivering sharper response on track days, fast road and competition use. Expect crisper turn-in, better traction out of corners and far more confidence when pushing on.

• Uprated poly bush kit for the inner mounting of the rear lower arm to reduce flex and unwanted compliance
• 95A hardness polyurethane for precise camber and toe control during aggressive driving
• Direct-fit replacement for tired OE rubber parts to remove play and tighten the rear axle
• Durable and corrosion resistant for long service life on performance builds
• Proven on our own cars and customer vehicles with excellent feedback for grip, stability and consistency
