Rennline Tuneable Semi-Solid Engine Mount is the ultimate upgrade for Porsche 718 owners seeking improved performance,
precision, and adjustability. Designed to replace the compliant factory
rubber mounts, this system dramatically reduces unwanted engine movement,
delivering sharper acceleration, enhanced handling, and a significantly
improved shifter feel.
Perfect for both street and track use, this is a versatile, fully tunable solution that allows you to configure your Porsche’s performance exactly the way you want.
Key Features
- CNC
Machined Billet Aluminium Construction – built for strength,
precision, and durability.
- Tuneable
Inserts – includes three pairs of polyurethane inserts in
different densities:
- Yellow (65A) – softest, for daily driving comfort and reduced slop.
- Blue (75A) – balanced stiffness for aggressive street and light track use.
- Red (85A) – stiffest, designed for full race applications. - Nine
Possible Combinations – mix and match inserts to fine-tune mount
stiffness for your driving style.
- Improved Driving Feel – reduces engine slop, prevents missed shifts, and increases drivetrain responsiveness.
- Street or Track Ready – softer inserts preserve comfort, while stiffer ones maximise control under racing conditions.
Why Replace Your Factory Engine Mounts?
Factory Porsche engine mounts use compliant rubber that
softens over time, causing:
- Excessive
Engine Movement – leading to sloppy acceleration and handling.
- Reduced
Shifter Precision – missed shifts or vague gear changes.
- Inconsistent Performance – especially under high load or during spirited driving.
Upgrading to the Rennline M143 semi-solid mount eliminates
these issues, transforming your Porsche with sharper responses, stronger
acceleration, and improved driver confidence.
Benefits of the Rennline M143
- Customisable
Performance – nine stiffness options let you tailor comfort and
control.
- Motorsport-Inspired
Design – ideal for both road cars and dedicated track builds.
- Enhanced
Longevity – billet aluminium body and durable polyurethane inserts
last far longer than factory rubber.
- Confidence in Every Drive – Rennline products are built by Porsche enthusiasts for Porsche enthusiasts, ensuring quality and excellence.
Upgrade your Porsche 718 with the Rennline M143 Tuneable Semi-Solid Engine Mount – the most adjustable, performance-focused mount available, giving you the freedom to tune your car for the street, the track, or anywhere in between.

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.
