Its separate polyurethane pieces, sleeve and washers form one mounting assembly. The complete Porsche carrier, engine support structure and other drivetrain mounts are not included.Road Series or Black SeriesChoose the exact supplier reference in the variant selector. Black Series is intended for track and motorsport priorities. Changes to engine mounting stiffness can affect transmitted vibration, so consider how the car is used and the condition of its other mounts.Insert alternativeWhen the original rubber is sound and an insert is the intended upgrade, see the PFR57-521 engine mount insert. An insert is not a substitute for replacing damaged rubber.Use the manufacturer's fitting instructions and correctly support the engine. Browse the Powerflex range. Confirm engine code and mounting reference before purchase; there is no blanket fitment guarantee.
