PFR5-4612 Rear Axle Carrier Front Mount Insert - BMW E46 M3 and Z4M

Transform the rear end feel of your BMW with this PFR5-4612 polyurethane insert set. Designed to locate in the voids of the factory front mounts on the rear cradle, these bushing inserts curb unwanted cradle movement for a tighter, more predictable drive. Expect crisper response, a more planted rear, and greater confidence on fast road and track days without resorting to solid mounts.

Crafted from tough, performance-grade polyurethane, this insert kit reinforces the OE rubber, helping control geometry under load for consistent traction and better tyre contact. It is a straightforward enhancement that complements the original bush - no pressing out required - and is supported by a lifetime warranty for peace of mind.

Why enthusiasts choose this upgrade

  • Limits rear cradle shift to improve stability through corners and over bumps
  • Sharper response to steering inputs with more consistent alignment control
  • Improved traction on acceleration and reduced wheel hop under hard launches
  • Durable polyurethane resists oil, road grime and ageing for long service life
  • Insert design fits into OE bush voids for a quick, cost-effective install
  • Backed by a lifetime warranty from the manufacturer

Fitment

For BMW E46 M3 and BMW Z4 M models only. The inserts locate within the cavities of the original front mounts on the rear axle carrier.
