Overview:

The ACT Flywheel Streetlite is a high-performance replacement flywheel designed specifically for select Subaru and Toyota sports models, including the Impreza, Scion FR-S, Subaru BRZ, and Toyota 86. Engineered to be significantly lighter than the stock flywheel, the Streetlite reduces rotational mass, improving throttle response and acceleration. This flywheel is ideal for enthusiasts seeking enhanced street performance or those participating in drag racing, offering a balance of durability and lightweight design without sacrificing reliability.

Built with precision and durability in mind, the Streetlite flywheel is serviceable and can be resurfaced multiple times, eliminating the need for frequent replacements. Its design ensures consistent clutch engagement and long-lasting performance, making it a trusted upgrade for daily drivers and weekend racers alike.

Key Features:

The ACT Streetlite flywheel incorporates advanced engineering and materials to deliver superior performance and reliability. Key features include:

• Significantly lighter than the OEM flywheel for reduced rotational inertia and improved engine response
• Heat-treated forging for enhanced strength and toughness under high-stress conditions
• Induction-hardened ring gear for maximum durability and extended service life
• One-piece construction minimizes failure points and ensures uniform heat transfer from the clutch disc
• Forged and CNC machined for precise fitment and balanced for smooth operation at high RPMs
• Serviceable design allows resurfacing without the need for additional parts
• Recommended for both street and drag racing applications
• Backed by ACT’s industry-leading one-year warranty

Construction & Design:

The Streetlite flywheel is crafted from high-grade forged steel, providing a robust yet lightweight component that withstands the rigors of spirited driving and racing. The heat treatment process enhances the material’s strength and resistance to warping, while the induction-hardened ring gear ensures reliable engagement with the starter motor over extended use. The one-piece design eliminates common issues found in multi-piece flywheels, such as loose ring gears or warped inserts, resulting in a more durable and consistent clutch interface.

Precision CNC machining and dynamic computer balancing guarantee smooth operation, reducing vibrations and stress on the drivetrain. This meticulous construction supports high RPM reliability and contributes to a more responsive driving experience.

Performance & Sound

By reducing the flywheel’s mass, the Streetlite improves engine throttle response and acceleration, allowing the engine to rev more freely and quickly. Drivers will notice a sharper, more immediate power delivery, especially beneficial in performance driving scenarios. While the flywheel maintains near-stock gear rattle levels, it enhances overall drivetrain feel without introducing excessive noise or harshness.

Installation & Fitment:

The ACT Streetlite flywheel is a direct bolt-on replacement for the specified Subaru Impreza (2006–2014), Scion FR-S (2013–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020) models. Installation requires standard flywheel removal and clutch servicing procedures, with no modifications necessary. Its compatibility with OEM clutch components ensures a straightforward upgrade path for enthusiasts and professional installers alike.

What's Included:

• ACT Flywheel Streetlite (Part #600480)
• Induction-hardened ring gear installed
• One-year manufacturer warranty documentation

Ideal For:

This flywheel is perfect for drivers seeking improved throttle response and acceleration on the street or at the drag strip. It suits enthusiasts upgrading their clutch system for better performance without sacrificing durability or requiring frequent replacements. The Streetlite is also an excellent choice for mild to moderate power builds where a lightweight, reliable flywheel is essential.
