This Powerflex polyurethane bush insert is the go-to suspension upgrade for sharper handling, improved stability and reduced subframe movement on the BMW E90, E91, E92 and E93 platforms. Ideal for daily road use, fast road driving and track day prep, these poly bushes control unwanted flex in the rear subframe without the excessive noise or harshness often associated with solid bushes.\u003c\/p\u003e\n\n  \u003cp\u003ePowerflex poly bushes are engineered to improve road holding and chassis performance by limiting subframe deflection. More precise location of the rear subframe means better turn-in, more consistent rear-end grip, improved braking stability and more even tyre wear. Correctly formulated polyurethane can match or exceed OEM rubber for NVH control while maintaining performance and longevity. This is a proven, cost-effective BMW suspension upgrade that delivers real-world results.\u003c\/p\u003e\n\n  \u003ch3\u003eFitment\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eBMW 3 Series E90 Saloon 2005–2013\u003c\/li\u003e\n    \u003cli\u003eBMW 3 Series E91 Touring 2005–2013\u003c\/li\u003e\n    \u003cli\u003eBMW 3 Series E92 Coupe 2006–2013\u003c\/li\u003e\n    \u003cli\u003eBMW 3 Series E93 Convertible 2007–2013\u003c\/li\u003e\n    \u003cli\u003ePosition: Rear Subframe Rear Mounting Insert\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003ePart Details\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003ePart number: PFR5-421\u003c\/li\u003e\n    \u003cli\u003eDiagram reference: 20\u003c\/li\u003e\n    \u003cli\u003eNumber of bushes in the pack: 2\u003c\/li\u003e\n    \u003cli\u003eType: Insert to be used with the OE rubber bush\u003c\/li\u003e\n    \u003cli\u003eFull replacement option available: PFR5-422\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eWhy choose Powerflex PFR5-421 for your BMW E90, E91, E92, E93?\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eReduces rear subframe movement to sharpen handling and steering response\u003c\/li\u003e\n    \u003cli\u003eImproves traction and braking stability for safer, more predictable performance\u003c\/li\u003e\n    \u003cli\u003eHelps minimise uneven tyre wear and prolong tyre life\u003c\/li\u003e\n    \u003cli\u003eDurable polyurethane bushings outlast standard rubber bushes\u003c\/li\u003e\n    \u003cli\u003eCost-effective BMW suspension upgrade with excellent value\u003c\/li\u003e\n    \u003cli\u003eLifetime warranty from Powerflex\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eReal-world results\u003c\/h3\u003e\n  \u003cp\u003eWe have installed Powerflex PFR5-421 rear subframe inserts on multiple E9x 3 Series builds and customer cars.
