Flywheel For Clutch, 225 mm.
The OE Match Flywheel for Clutch, 225 mm is a precision-engineered replacement drivetrain component designed to transfer engine power efficiently to the clutch assembly and transmission. Manufactured to OE specifications for fit, balance and durability, this flywheel provides the correct friction surface for clutch operation while helping to smooth engine power delivery and reduce drivetrain vibration.  

Fits:

• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC  

Machined from high-quality materials to ensure strength and long service life, the flywheel acts as a rotating mass attached to the crankshaft, storing kinetic energy and providing a stable platform for clutch engagement. Its 225 mm clutch contact surface is designed to maintain factory performance characteristics and reliable operation.  

What This Product Does:

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

Symptoms Of Wear Or Failure:

• Clutch shudder or judder during take-off.
• Excessive vibration through the drivetrain.
• Difficulty achieving smooth clutch engagement.
• Hot spots or scoring on the flywheel surface.
• Premature clutch wear.
• Burning clutch odours during operation.
• Rattling or knocking noises from the bellhousing area.
• Warped clutch friction surface.
• Uneven clutch pedal feel or engagement characteristics.
• Reduced overall driving refinement.

Why Replacement Matters:

• The flywheel is subjected to continuous engine torque, clutch friction and repeated heat cycles throughout its service life. Over time, the friction surface can become worn, heat-damaged, cracked or warped, affecting clutch performance and overall drivability.
• A damaged flywheel can lead to clutch vibration, poor engagement characteristics and accelerated wear of the clutch disc and pressure plate. Installing a new clutch on a worn flywheel may result in reduced clutch lifespan and continued drivability issues. In severe cases, excessive wear or damage can compromise drivetrain reliability and increase repair costs.
• Replacing a worn flywheel restores smooth clutch operation, improves gear engagement and helps maximise the performance and longevity of the clutch system. An OE Match replacement provides factory-style fitment, precise balancing and durable construction, ensuring dependable operation and preserving the driving experience expected from your Porsche.
