PFR5-4611 Polyurethane Rear Crossmember Mount Pair for BMW E46 3 Series, X3 E83, Z4 E85 E86 E89

Transform the way your BMW drives with this Road Series polyurethane rear axle carrier mount kit. By replacing tired factory rubber with high-performance poly, these mounts control subframe movement, sharpen turn-in and deliver a planted, confidence-inspiring rear end on British roads. Expect crisper cornering, better traction out of bends and more consistent geometry under braking and acceleration.

Built to last and resistant to oil, road salt and heat, these bushes are a superb long-term upgrade for daily use and spirited driving. We have installed this exact kit on our own cars and for many customers, and feedback is consistently positive on stability, steering response and overall drivability.

Why this upgrade

If your BMW feels floaty at the rear, clunks over bumps, or wanders under load, worn crossmember mounts are often the cause. Swapping to these polyurethane carrier mounts tightens the rear axle location, reduces unwanted deflection and restores the direct, connected feel keen drivers want.
