For the revision of your Porsche engine, we offer this engine mount. The flange surface with your cantilevers to the mounting axis allows a secure and at the same time easily accessible attachment of the engine to a rolling engine stand. Alternatively, you can use the engine mount to mount the engine to a workbench using a bearing block. We have the engine stands for all classic Porsches with and without a mounting stand in our program.

Notice: The colour of the part may differ from the colour shown.

One of the only weak points on the 964 and 993 chassis is the engine carrier. When these models are tracked, or are fitted with stiffer than stock engine mounts, the engine carrier should be reinforced. If it is not, the carrier is known to bend, crack, or even break cleanly away from an engine mount in response to increased vibration and stress. The Porsche factory was aware of this problem and equipped its race cars with a reinforced engine carrier. Rennline now exclusively offers an engine mount reinforcement gusset kit that can be welded to the engine carrier by your workshop.

The Porsche factory was aware of this problem and equipped its race cars with a reinforced engine carrier. Rennline now offers a tube frame replacement for your factory engine carrier that is proven to be much stronger, and can withhold the stresses of any track day, while offering a 1.4lb weight savings over a gusseted factory carrier. All parts manufactured on cnc equipment and meticulously tig welded, finished with a matte black powdercoat.

About Engine Mounts

Replacement Engine Mounts – Stability, Comfort, and Performance for Porsche Models

Engine mounts are the unsung heroes of your Porsche’s drivetrain, securing the engine to the chassis while absorbing vibration and maintaining precise alignment. Over time, these components can degrade from constant heat, torque, and road stress — affecting ride quality, handling, and drivetrain performance.

At Design911, we supply a wide selection of precision-engineered replacement engine mounts designed to the highest performance standards. Manufactured from high-grade rubber, polyurethane, or reinforced composite materials, these mounts provide the perfect balance of vibration isolation and structural support.

Whether you’re restoring a classic air-cooled model or maintaining a modern 911, manufacturer-quality mounts ensure smooth operation, improved comfort, and precise drivetrain alignment under all conditions.

What Do Engine Mounts Do?

Engine mounts secure the engine and transmission to the vehicle’s chassis, minimising movement while isolating vibrations that would otherwise transfer into the cabin.

Core Functions:

  • Securely position the engine and transmission within the chassis.
  • Absorb vibration and torque movement, improving comfort and handling.
  • Maintain drivetrain alignment for optimal power transfer.
  • Reduce stress on components such as hoses, wiring, and exhaust connections.

Well-fitted engine mounts preserve your Porsche’s distinctive refinement and handling precision, especially under high load or spirited driving.

Why Do Engine Mounts Fail?

Due to constant exposure to torque, heat, and vibration, engine mounts naturally degrade over time. Worn or broken mounts can lead to excessive engine movement, clunking noises, and vibration inside the cabin — symptoms that should never be ignored.

Common Causes of Engine Mount Failure Include:

  • Material fatigue from age or repeated heat cycling.
  • Oil contamination, softening rubber or polymer components.
  • Excessive engine torque or vibration, especially on tuned or high-mileage engines.
  • Corrosion or cracking in metal brackets or hardware.
  • Improper installation leading to uneven stress and premature wear.

Failing mounts compromise performance and comfort, causing drivetrain misalignment and potential damage to surrounding components.

Why Replace with Precision-Engineered Engine Mounts?

Upgrading to high-quality replacement engine mounts restores the stability, refinement, and handling balance your Porsche was designed for. Precision-engineered mounts ensure reliable load distribution, vibration damping, and improved driving comfort.

Key Benefits:

  • Restores drivetrain stability and precise engine positioning.
  • Reduces vibration and harshness, improving cabin comfort.
  • Enhances throttle response by limiting engine movement.
  • Protects critical components from stress and misalignment.
  • Available in rubber or performance polyurethane for tailored ride feel.
  • Perfect fitment across Porsche models — air-cooled, turbocharged, or hybrid.

Whether you’re maintaining daily drivability or preparing for track use, replacement mounts deliver the durability and control your Porsche deserves.

Highlights:

  • Precision-engineered replacement engine mounts for all Porsche models.
  • High-grade rubber, polyurethane, or reinforced construction.
  • Improves handling, comfort, and vibration isolation.
  • Direct-fit compatibility for easy installation and perfect alignment.
  • Ideal for rebuilds, performance upgrades, or preventive maintenance.
  • Restores driving dynamics and comfort in classic and modern Porsches.
