Powerflex PFR5-423 Rear Carrier Mount Insert Bush for BMW E8x and E9x AWD Manual

Transform the way your BMW tracks, turns and puts power down with this uprated rear cradle mounting insert from Powerflex. The PFR5-423 Road Series polyurethane insert controls movement at the back axle crossmember, giving a tighter, more connected feel and greater stability on British roads without the vagueness associated with tired factory rubber. Ideal for daily use and fast-road driving, this is a proven chassis upgrade we run on customer cars and our own builds with excellent feedback on precision and confidence.

• Road Series polyurethane insert for long-lasting performance in all weather conditions
• Limits rear cradle shift for cleaner turn-in, improved traction and more consistent handling
• Helps maintain rear alignment under load for predictable, repeatable response
• Direct-fit insert design for straightforward installation with no special fabrication
• Durable upgrade that outlives ageing rubber components
