Description

The ACT Streetlite Flywheel Kit (Part Number 600145-03) is a premium performance upgrade engineered for Mazda RX-7 and RX-8 models, offering enhanced engine response, acceleration, and durability. This kit features a lightweight forged flywheel with an integrated counterweight — essential for maintaining correct external balance in rotary-engine manual transmission applications.

Constructed from heat-treated forged steel, the Streetlite Flywheel delivers exceptional strength and toughness while maintaining a lightweight, low-inertia profile that allows the engine to rev freely and respond instantly. The induction-hardened ring gear ensures long-term durability and consistent engagement under extreme load and temperature conditions. CNC machining and dynamic balancing provide smooth, vibration-free performance at high RPMs, improving driveline stability and throttle control.

Optimized material distribution enhances strength and heat tolerance, making this flywheel ideal for street, drag, and competitive applications. It is fully serviceable and can be resurfaced without replacement parts, offering cost-effective maintenance and long-term reliability. Engineered for precision and performance, the ACT Streetlite Flywheel Kit provides rotary enthusiasts with the perfect combination of balance, strength, and responsiveness.

Features:

  • Lightweight design: Significantly reduces rotational inertia for quicker acceleration
  • Durable construction: Heat-treated forging and induction-hardened ring gear for maximum lifespan
  • Properly balanced: CNC-machined and dynamically balanced for smooth high-RPM operation
  • Includes counterweight: Ensures correct external balance for manual transmission applications
  • Compatible with multiple Mazda RX-7 and RX-8 models: Fits a range of years including 2004-2011
