The release of the WEVO Semi-Solid Engine Mount: the first non-solid aftermarket engine mount developed specifically for 911 engine mount applications.

Engine Mount Application:  911’s  1964-1989 (1 set of two)

Transmission Mount Application:  911’s 1972-1986 (1 set of 2)

The WEVO SS Engine Mount is designed to offer virtually the same locating advantages of a solid engine mount, without the metal-to-metal contact between the chassis and the engine.

The SS Engine Mount comprises of 5 components. The design of the components ensures that at rest, or idle, the engine is firmly located, but free to vibrate against the elastomeric pillows isolating the engine mount inner and outer components. When the engine reacts to torque, the components deflect slightly and the spring rate of the isolators is progressively increased, improving the location of the engine and transmission under more stressful conditions.

The design is such that metal to metal contact is always avoided, so potentially harmful misalignment forces and vibrations are managed in a manner more similar to the original factory rubber mounts. The SS Engine Mounts are installed using the original hardware and have a gold anodized finish similar in appearance to the gold zinc plated factory parts.

The SS Engine Mount is an upgrade suited to cars used for spirited road driving all the way through full race cars. Testing on road and track cars has shown a significant reduction in vibration transmitted versus solid mounts, without reduction in chassis performance, or gear selection accuracy.

Owners of cars with Weber or PMO carburetors will be pleased to know that development of this product was encouraged by Richard Parr at PMO as a way of protecting against carburetor issues related directly to engine vibrations. Also available with stiffer Blue pillows – see our catalogue.

NOTE: A 914 transmission mount version is also available (914 SS Transmission Mounts). The 914 hole spacing is close – but not the same as the 911 and the WEVO SS Engine Mount body should not be slotted.

Technical Note: The M12 bolt through the Engine or Transmission mount should be tightened to 40 ft/lbs or 55 Nm. The M12 Schnorr (serrated) washer should be installed directly under the head of the M12 bolt. The M8 hardware should be tightened to 18 ft/lbs or 25 Nm using the original arrangement of washer and nut.
