OVERVIEW

The perfect balancing act between razor-sharp throttle response and seamless everyday street manners. Weighing in at 21 lbs, the Clutch Masters Single-Mass Lightweight Steel Flywheel strips away significant rotational weight compared to the heavy factory assembly without losing the inertia required for comfortable daily driving. This precision CNC-machined upgrade delivers faster rev matching, noticeably minimizes turbo lag coming out of standard corners, and retains smooth low-RPM street operations.

FEATURES

• Billet Steel Longevity: Precision CNC-machined in the USA from ultra-durable premium 1045 billet steel to guarantee flawless structural integrity at high engine speeds.
• Street-Balanced 21 lbs Mass: Shaves off rotating weight to optimize throttle acceleration while retaining adequate thermal mass to suppress annoying gearbox rattle and idle chatter.
• Replaceable Friction Liner: Outfitted with an innovative, replaceable high-carbon steel insert face—allowing quick, cost-effective rebuilds without forcing you to buy a whole new flywheel or pay for complex resurfacing shops.
• SFI Certified Safety: Fully evaluated and certified under strict SFI motorsport standards to confirm complete high-RPM burst protection on the track.
• Reduced Turbo Lag: Drastically lowers rotational inertia to help the 1.6L turbocharged engine climb into its effective powerband sooner under acceleration.
