Dial out unwanted movement at the back of your BMW and unlock sharper, more planted handling with this Black Series rear axle carrier front position insert kit. Using a motorsport-grade 95 Shore A polyurethane compound, these inserts stabilise the rear cradle under load for crisper turn-in, cleaner power delivery and a more connected drive. A brilliant upgrade for enthusiastic road use, fast road builds and track days without the hassle of pressing out the factory rubber mount.

Why enthusiasts choose this upgrade

• Locks down the rear axle carrier to reduce squirm and flex under acceleration and braking
• Improves cornering stability and rear-end composure for predictable, confidence-inspiring dynamics
• Cuts wheel hop and shunt for cleaner traction and smoother throttle transitions
• Keeps rear alignment more consistent under load to help tyres work harder for longer
• Track-focused Black Series polyurethane resists oil, abrasion and high loads for long service life
• Insert-style fitment retains the OE rubber mount for faster installation and less downtime

Real-world results from our workshop: we have fitted this kit to multiple X5 and X6 builds and feedback is consistently positive. Customers report a tighter rear end, better stability at speed and more precise responses when pushing on. As with any competition compound, a small increase in noise, vibration and harshness is normal, which is a worthwhile trade for the control it delivers.
