Flywheel / Torque

Flywheel.
The OE Match Flywheel is a high-quality replacement drivetrain component designed to transfer engine power smoothly to the clutch assembly and transmission while maintaining optimal engine balance and drivability. Manufactured to OE specifications for fit, weight distribution, balance and durability, this flywheel provides the critical interface between the engine crankshaft and clutch system.  

Fits:

Precision-machined from high-grade materials, the flywheel stores rotational energy generated by the engine and helps deliver smooth, consistent power to the drivetrain. It also provides the friction surface required for clutch engagement, making it an essential component for reliable power transfer, smooth gear changes and overall vehicle performance.  

What This Product Does:

• Transfers engine torque to the clutch and transmission.
• Provides the clutch friction surface for engagement and disengagement.
• Stores rotational energy to smooth engine operation.
• Helps maintain stable idle characteristics.
• Reduces drivetrain vibration and engine pulsations.
• Supports smooth gear changes and clutch performance.
• Contributes to efficient power delivery and drivability.
• Maintains correct balance within the engine and drivetrain assembly.

Symptoms Of Wear Or Failure:

• Clutch judder or shudder during take-off.
• Excessive drivetrain vibration.
• Uneven or inconsistent clutch engagement.
• Difficulty achieving smooth gear changes.
• Scoring, cracking or heat spots on the flywheel surface.
• Premature clutch wear.Burning clutch odours.
• Rattling or knocking noises from the bellhousing area.
• Excessive clutch slippage under load.
• Reduced overall driving comfort and performance.

Why Replacement Matters:

• The flywheel is subjected to significant mechanical loads, heat cycles and friction generated by clutch operation. Over time, the clutch contact surface can become worn, warped or heat-damaged, affecting clutch engagement and overall drivetrain performance.
• A damaged flywheel can cause vibration, poor clutch operation and accelerated wear of the clutch disc and pressure plate. Continuing to operate with a worn flywheel may compromise the performance of new clutch components and increase the likelihood of more extensive transmission and drivetrain repairs.
• Replacing a worn or damaged flywheel restores smooth power transfer, improves clutch engagement and helps maximise the lifespan of associated clutch components. An OE Match replacement provides factory-style fitment, precision balancing and durable construction, ensuring reliable performance and preserving the driving characteristics expected from your Porsche.

Lightweight Flywheel Conversion, 200mm For 12V Starter Motor.
Upgrade your Porsche drivetrain with this OE Match Lightweight Flywheel Conversion, 200mm for 12V Starter Motor. Produced to OE-style specifications, this lightweight flywheel conversion is engineered for vehicles using a 12-volt starter motor, providing the correct fitment while significantly reducing rotational mass for improved engine responsiveness. Manufactured from high-quality forged steel and precision balanced for smooth operation, it delivers exceptional strength, excellent resistance to heat and fatigue, and long-lasting durability. It is an ideal solution for performance builds, engine upgrades, clutch replacements, and restoration projects where improved drivability and faster engine response are desired.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63
• Porsche 356C 1963-65  

The lightweight flywheel is a critical component within the engine and transmission assembly, storing rotational energy while providing the friction surface for the clutch. Compared to a standard flywheel, the lightweight design reduces rotational inertia, allowing the engine to rev more freely, accelerate faster, and deliver sharper throttle response. The integrated conversion is specifically designed for compatibility with 12V starter motor applications, ensuring correct starter engagement and reliable operation. Over time, flywheels can become heat damaged, warped, cracked, or scored through repeated clutch use, leading to poor clutch engagement and driveline vibration. Replacing the flywheel restores dependable clutch operation while delivering the performance benefits of reduced rotating mass.  

What This Product Does:

• Reduces rotating mass for improved engine responsiveness.
• Provides the friction surface for the clutch assembly.
• Improves throttle response and engine acceleration.
• Supports smooth clutch engagement and disengagement.
• Converts compatible applications for use with a 12V starter motor.
• Replaces worn, cracked, or heat-damaged flywheels.
• Provides an OE-style fit for straightforward installation.

Symptoms Of Wear Or Failure:

• Clutch judder during engagement.
• Excessive drivetrain vibration.
• Heat spots or scoring on the flywheel surface.
• Cracked or warped flywheel.
• Difficulty achieving smooth clutch engagement.
• Premature clutch wear or persistent clutch slippage.
• Starter engagement issues caused by damaged ring gear.
• Damage identified during clutch replacement or engine overhaul.

Why Replacement Matters:

• The flywheel is fundamental to transmitting engine power to the transmission while providing the precision-machined surface required for proper clutch operation. A worn or damaged flywheel can cause clutch vibration, inconsistent engagement, accelerated clutch wear, and starter motor issues. A lightweight flywheel conversion not only restores reliable operation but also reduces rotational inertia, allowing the engine to rev more quickly and deliver noticeably sharper throttle response. The dedicated 12V starter motor compatibility ensures proper starter engagement and dependable starting performance.
• Replacing a worn flywheel with this OE Match Lightweight Flywheel Conversion restores smooth clutch operation, enhances engine performance, and improves overall driving enjoyment. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Lightweight Flywheel Conversion, 200mm for 12V Starter Motor provides reliable fit, exceptional strength, and long-lasting durability for Porsche maintenance, performance upgrades, repairs, and restoration projects.
