The WEVO Semi-Solid Engine Mount is the first non-solid aftermarket engine mount developed specifically for Porsche 911 applications. Factory rubber mounts allow too much deflection, causing drivability to feel somewhat imprecise. Solid aftermarket mounts increase responsiveness by fixing the engine location, but the metal-to-metal contact between the chassis and the engine is almost too rigid - which could ultimately affect the reliability of the vehicle.

Instead of compliant rubber or solid metal, the WEVO SS Engine Mounts utilize special elastomeric pillows to absorb vibration while minimizing drivetrain deflection. This exclusive design is thus the best of both worlds - providing a near-rigid engine mounting system while maintaining a quiet and comfortable ride. Use them for the street or the track - they're the most advanced engine mounts you can install on your 911!

These C2 SS Engine mounts offer more precise location than the factory RS mounts - and do so at a lower price. An ideal compromise between the harshness of solid mounts and the cost of the factory RS mounts.

The kit includes the correct M12 bolt to install these mounts as replacements for the Hydroelastic O.E. mounts (that uses an integral stud).

The "Black" Pillows are 15 points softer on the Shore "A" scale for durometer readings than the original "Blue" Pillows. The Black pillows function in the same way as the Blue pillows - although they allow slightly more deflection under similar loads - the advantage is lower noise transfer through the SS mount module.

Black pillows are recommended for street use or occasional track use. For pure track work, Blue pillows are recommended. Blue and Black pillows can also be mixed in any combination - including mixing them within a single mount body. This provides you with the flexibility to suit your exact needs.
