Clutch Masters FW-616-AL Lightweight Aluminum Flywheel for 23-25 Toyota GR

Vehicle Fitment

• 2023-2025 Toyota GR Corolla (1.6L G16E-GTS Turbo 3-Cylinder, GZEA14, 6-Speed iMT Manual Transmission, GR-FOUR AWD)

Fitment Notes

• 6-speed manual transmission (iMT) only - the GR Corolla is exclusively offered with a manual transmission
• Does not fit standard Corolla, Corolla Hatchback, or Corolla Cross models - GR Corolla only
• This is a standalone flywheel - not a complete clutch kit; designed for use with Clutch Masters 16616-series single disc clutch kits
• Replaces factory flywheel with a lightweight aluminum single-mass flywheel
• This flywheel is designed for track use - will produce significant gearbox chatter at idle on the street
• For primarily street-driven GR Corollas, Clutch Masters recommends the steel flywheel (FW-616-SF, 21 lbs) for reduced noise and improved daily-driving refinement
• Includes replaceable steel friction insert - eliminates need to resurface the flywheel at future clutch services

Features

• Lightweight aluminum flywheel machined from 6061-T6 billet aluminum
• CNC-machined to exact tolerances - designed in CAD and precision machined in-house on Haas CNC lathes
• Type 3 hard coat anodized for exceptional durability, heat resistance, and corrosion protection
• Precision zero-balanced during machining for even weight distribution and 100% true rotation
• Replaceable steel friction insert - simply replace the insert at each clutch service rather than resurfacing the flywheel
• Dramatic weight reduction over factory flywheel for faster engine acceleration, quicker revs, and improved throttle response
• Reduces turbo lag by decreasing rotational inertia on the crankshaft - particularly beneficial for the GR Corolla's small-displacement high-boost 1.6L turbo engine
• SFI certified for competition in sanctioned racing events
• Designed and manufactured in the USA

Specifications

• Type: Lightweight single-mass aluminum flywheel for single disc clutch kits
• Material: 6061-T6 billet aluminum, Type 3 hard coat anodized
• Friction Surface: Replaceable steel insert (included)
• Weight: 12 lbs
• SFI Certification: Yes
• Country of Manufacture: USA

Included Components

• 1x 6061-T6 billet aluminum flywheel (CNC-machined, Type 3 hard coat anodized, zero-balanced)
• 1x Replaceable steel friction insert (pre-installed)

Product Description

The Clutch Masters FW-616-AL is a lightweight aluminum flywheel designed for the 2023-2025 Toyota GR Corolla equipped with the 1.6L G16E-GTS turbocharged 3-cylinder engine and 6-speed iMT manual transmission. At just 12 lbs, this flywheel provides a dramatic reduction in rotational mass compared to the factory flywheel, resulting in significantly faster engine acceleration and deceleration, sharper throttle response, and reduced turbo lag. The GR Corolla's small-displacement, high-boost 1.6L turbo engine is particularly responsive to reductions in flywheel mass - the lighter rotating assembly allows the engine to spool faster and rev more freely, delivering a more immediate and connected driving experience that is transformative on track.

The flywheel is CNC-machined from a solid 6061-T6 billet aluminum core sourced from US manufacturers and guaranteed free of impurities or defects. Every flywheel is precision zero-balanced during machining to ensure even weight distribution and vibration-free rotation at high RPM. The Type 3 hard coat anodizing provides the ultimate protection against wear, heat, and corrosion. The replaceable steel friction insert is a key design feature - rather than resurfacing the entire flywheel at each clutch service, the insert can simply be replaced, extending the flywheel's usable life indefinitely and reducing long-term maintenance cost.

Clutch Masters explicitly notes that this aluminum flywheel is designed for track use and will produce significant gea
