Unlock precision and confidence with this polyurethane front mount set for the rear axle carrier. The Powerflex PFR5-720 kit replaces ageing rubber to curb sub-frame shift, keep alignment stable and deliver sharper turn in, stronger traction and more consistent braking performance. Perfect for fast-road driving and daily use with long-lasting durability.

We fit these on our own builds and for customers, and the results speak for themselves: a tighter rear end, steadier high-speed behaviour and noticeably less tyre scrub. It is a simple upgrade that transforms the way your E63 or E64 feels on the road.

Key reasons to upgrade

• Stabilises the rear carrier to maintain geometry under acceleration, cornering and hard stops
• Enhances road holding and rear-end composure for a more connected, confidence-inspiring drive
• Helps reduce uneven tyre wear by limiting unwanted movement
• Polyurethane compound balances firmness with comfort and excellent control of NVH
• Backed by the Powerflex Lifetime Warranty for total peace of mind
