A bracket is not a diagnosis or guaranteed cure for every rear-end knock or wheel-hop problem. Inspect the existing mounts and use the Powerflex fitting instructions. Bush choice can affect transmitted noise and vibration. Check the chassis and existing mounting arrangement before ordering; there is no blanket fitment guarantee.\u003c\/p\u003e\u003cp\u003eBrowse the \u003ca href=\"\/collections\/powerflex-performance-polyurethane-bushes\"\u003ePowerflex bushes and differential mounting range\u003c\/a\u003e.\u003c\/p\u003e\u003cdiv class=\"n72-tech-link\"\u003e\n\u003ch2\u003eBMW F8x differential mount technical guide\u003c\/h2\u003e\n\u003cp\u003eNot sure whether you need an individual bush, the PFR5-4030 bracket or a complete differential mounting package?
