Powerflex's PFR5-4030 dual bracket is separately catalogued for F8x models. The shared PFR5-4026 rear bush does not establish G8x bracket compatibility, so an F8x complete kit must not be substituted on that basis.\u003c\/p\u003e\u003ch2\u003eFitting considerations\u003c\/h2\u003e\u003cp\u003eInspect the mountings and follow the manufacturer's fitting instructions. Polyurethane can change the amount of drivetrain noise and vibration reaching the cabin; it is not a guaranteed cure for every rear-end symptom.
