Clutch Masters Lightweight Steel Flywheel

2005–2010 Scion tC

Part #: FW-725-SF

Overview

The Clutch Masters Lightweight Steel Flywheel is a precision-engineered upgrade designed specifically for the 2005 to 2010 Scion tC. This flywheel reduces rotational mass compared to the stock unit, delivering quicker engine response and improved acceleration. It is an ideal choice for enthusiasts looking to enhance throttle response, reduce turbo lag, or improve mid-range torque in naturally aspirated setups. Whether you drive a daily or a performance-oriented vehicle, this flywheel offers a noticeable improvement in drivability and engine efficiency.

By lowering the flywheel’s weight, the engine can rev more freely, allowing for faster power delivery and smoother shifts. This upgrade is especially beneficial for turbocharged engines, where reduced inertia helps minimize turbo lag, but it also enhances naturally aspirated engines by reducing parasitic drag on the crankshaft.

Key Features

Clutch Masters has engineered this flywheel to deliver reliable performance and durability. Key features include:

• Lightweight steel construction reduces rotational mass for quicker acceleration
• OEM steel ring gear securely bolted for reliable starter engagement
• Improves turbocharger response by reducing typical turbo lag
• Enhances supercharger efficiency by lowering parasitic drag on the crankshaft
• Boosts mid-range torque in naturally aspirated engines by eliminating the heavy stock flywheel inertia
• Meets stringent SFI Spec 1.1 or 1.2 safety standards
• Limited lifetime warranty from Clutch Masters for peace of mind

Construction & Design

The flywheel is crafted from high-quality billet steel, ensuring exceptional strength and durability under demanding driving conditions. Clutch Masters utilizes a bolted OEM steel ring gear, which guarantees consistent starter engagement and longevity. The design focuses on reducing weight without compromising structural integrity, making it suitable for both street and track use. The precision machining process ensures perfect balance and fitment, contributing to smooth engine operation and reduced vibrations.

Performance & Sound

By reducing the flywheel’s mass, this upgrade allows the engine to rev more freely, resulting in improved throttle response and quicker acceleration. Turbocharged engines benefit from a noticeable reduction in turbo lag, enhancing overall drivability. Naturally aspirated engines experience improved mid-range torque due to the decreased effort required to spin the flywheel. While the flywheel itself does not significantly alter exhaust sound, the improved engine responsiveness can contribute to a more engaging driving experience.

Installation & Fitment

This flywheel is a direct fit replacement for the 2005–2010 Scion tC, designed to work seamlessly with the factory clutch and drivetrain components. Installation requires standard mechanical skills and tools, including removal of the transmission to access the flywheel. It is recommended to inspect the clutch assembly and related components during installation and replace any worn parts to ensure optimal performance. Professional installation is advised for best results.
