Enhance drivetrain precision and performance with the HD Semi-Solid Engine / Transmission Mount Set, designed specifically for Porsche 911 and 912 models
These heavy-duty mounts replace the factory rubber units with a semi-solid, high-durometer compound — around 25 % firmer than standard — providing improved control and response without sacrificing comfort.
The semi-solid design effectively reduces engine and gearbox movement under acceleration, braking, and cornering, giving sharper throttle response, smoother gear changes, and tighter handling stability.
One kit includes 2 halves of mount, (2 kits required per car).
Fits:
Work as engine mounts in 1965-1989 911/912/930
Work as transmission mounts in 1972-1986 911/912/930 (915/930 Transmission Only)
What This Product Does:
- In the Heavy Dusty semi-solid version, the stiffer rubber reduces unwanted flex while still providing some damping, hence a compromise between fully soft and fully rigid (solid) mounts.
Symptoms / Indications That Replacement Or Upgrading Is Needed:
- Engine / gearbox movement or “rocking” under throttle or deceleration
- Clunking or banging noises from the engine bay when shifting or applying torque
- Increased vibration in the cabin or floorboard
- Misalignment over time, causing stress or wear in driveshafts, couplings, or mount brackets
- Feel of looseness or lag in throttle response or drivetrain “lash”
Why Upgrading to HD Semi-Solid Mounts Matters:
- Sharper Response & Less Flex - Because mounts deflect less, the engine / gearbox stays more stable under load, improving throttle response, shift feel, and power delivery.
- Better Drivetrain Alignment - Less movement helps maintain correct angle relationships between engine, gearbox, driveshafts, etc., reducing stress and wear.
- Improved Stability Under Load - During hard cornering, braking, or acceleration, stiffer mounts help avoid drivetrain “twist” or slop, which can upset handling balance.
- Dampening Retained - Semi-solid design still absorbs vibration and noise more than fully rigid mounts, providing a balanced tradeoff for street use.
- Straightforward Installation - Because the inserts fit existing mount shells, installation is simpler — no need for custom brackets or drastic modifications.
- Good for Performance / Restoration Builds - Especially in cars that see spirited driving or occasional track use, the HD semi-solid mounts are a common upgrade that improves control without completely sacrificing comfort.

Restore secure engine support, controlled drivetrain movement and refined operation with these OE Match Engine Mounts. Designed for compatible Porsche applications, the engine mounts provide the critical connection between the engine and vehicle chassis while helping isolate vibration generated by the powertrain.
Fits:
Porsche 970 Panamera S 2011-13
Porsche 970 Panamera GTS / Turbo 2011-16
Engine mounts must perform two important functions: securely support the weight and torque reaction of the engine while allowing a controlled amount of movement to prevent excessive vibration from being transmitted into the vehicle body.
During acceleration, deceleration and gear changes, the engine naturally attempts to move within the engine bay. Correctly functioning mounts limit this movement and keep the powertrain properly located. As mounts age, their rubber, hydraulic elements or internal construction can deteriorate, resulting in excessive movement and increased noise or vibration.
These OE Match Engine Mounts provide high-quality replacements for worn, collapsed or damaged original mounts, helping restore correct engine positioning and refinement.
What This Product Does:
- Supports and secures the engine within the chassis.
- Maintains correct powertrain positioning.
- Controls excessive engine movement under acceleration and deceleration.
- Helps manage torque reaction from the engine.
- Isolates engine vibration from the vehicle body.
- Helps reduce noise, vibration and harshness transmitted into the cabin.
- Supports smoother operation during starting and stopping.
- Helps maintain drivetrain stability during gear changes.
- Protects surrounding hoses, wiring and drivetrain components from excessive movement.
- Replaces a worn, collapsed, leaking or damaged engine mount.
- Helps restore OE-style engine support and refinement.
Symptoms Of Wear Or Failure:
- Excessive engine vibration at idle.
- Increased vibration felt through the cabin, seats or steering wheel.
- Clunking or knocking when accelerating or decelerating.
- A noticeable jolt when changing gear.
- Excessive engine movement when applying or releasing the throttle.
- Increased movement when engaging Drive, Reverse or a gear, depending on transmission type.
- Engine movement during starting or shutdown.
- Unusual drivetrain vibration under load.
- Engine appearing to sit lower or unevenly in the engine bay.
- Cracked, split or deteriorated mount material.
- Visible collapse or deformation of the mount.
- Fluid leakage from a hydraulic-style mount, where applicable.
- Contact or interference between the engine and surrounding components.
- Deterioration identified during engine or transmission servicing.
Why Replacement Matters:
- Engine mounts are essential for keeping the powertrain correctly positioned while isolating vibration from the chassis. When a mount deteriorates, the engine can move significantly more than intended.
- Excessive movement may be felt as clunks or jolts when accelerating, braking or changing gear. It can also make an otherwise correctly running engine feel noticeably rougher because more vibration is transmitted directly into the body.
- Movement of the powertrain can place additional stress on surrounding components. Exhaust connections, coolant hoses, intake components, electrical wiring and drivetrain connections may all experience additional movement when the engine is no longer properly restrained.
- A collapsed mount can also alter the physical position of the engine, potentially reducing clearance around neighbouring components.
- Replacing worn mounts can therefore improve more than cabin refinement. It helps restore correct drivetrain positioning and reduces unnecessary loads on components connected to or surrounding the engine.
- Replacing deteriorated originals with the appropriate OE Match Engine Mount helps restore controlled powertrain movement, reduced vibration and dependable engine support.
