Lightweight Clutch Flywheel, 225mm 3.9KG.
OE Match lightweight clutch flywheel engineered as a direct-fit replacement for the original factory flywheel on early Porsche 911 models equipped with a 225 mm clutch (typically 911/912 engines 1970–1977)
Fits:
Porsche 911 1970 - 1977
Diagram ref no 3
Lightweight flywheels are popular upgrades because they allow the engine to rev more freely and respond more quickly to throttle inputs - a benefit especially appreciated in spirited road use and track applications. The 225 mm diameter and bolt pattern ensure compatibility with standard 911 clutch kits, pressure plates, and housings designed for this generation.
Despite its reduced mass, this OE Match version maintains the structural integrity required for everyday driving and performance use, utilizing materials and manufacturing methods that align with Porsche engineering intent.
The lightweight clutch flywheel stores rotational energy and provides the mounting surface for the clutch pressure plate and friction disc. By reducing mass compared to heavier stock units, it lowers rotational inertia, which helps the engine accelerate more quickly and improves engine responsiveness.
Function:
When installed between the engine crankshaft and clutch assembly, this flywheel:
• Reduces rotational mass compared to standard flywheels
• Improves throttle response and engine rev-up behaviour
• Supports consistent clutch engagement and release
• Works with standard clutch disc and pressure plate assemblies .
he flywheel interface ensures proper alignment with the crank flange and provides the correct surface for the clutch friction disc to engage, which is critical for smooth power transfer and drivability.
Over time, original flywheels can become warped, worn, or damaged due to heat cycles, clutch slippage, or long-term use. A compromised flywheel can lead to uneven clutch engagement, noise, or vibration. Installing a new OE Match lightweight flywheel restores correct rotational dynamics and engagement surfaces, while the reduced mass enhances throttle responsiveness and engine feel.
When to replace:
• Clutch disc replacement or driveability issues
• Flywheel scoring, heat glazing, or warping
• Upgrading for improved throttle response
• Transmission service requiring flywheel removal
• Preventive refresh on high-mile engines
