Flywheel Ultra Light Subaru WRX GT/GR86 BRZ

The Flywheel Ultra Light Subaru WRX GT/GR86 BRZ from UNICLUTCH is engineered for drivers who demand sharper throttle response and reduced rotational inertia in their high-performance Subarus. This lightweight flywheel directly replaces the factory unit, making it ideal for street tuners, track enthusiasts, and anyone upgrading their WRX or BRZ's drivetrain for faster acceleration and quicker gear changes. By minimizing flywheel mass, you unlock the full potential of your engine's rev range without the sluggish feel of OEM iron.

UNICLUTCH's ultra-light design reduces rotating mass to just 10.405 lbs—a significant drop from stock—allowing your engine to accelerate faster between gear changes and respond immediately to throttle input. The optimized ring gear geometry maintains proper engagement with your starter motor while the precision-machined construction ensures concentricity and balance for vibration-free operation across all RPM ranges. The compact 15.15-inch diameter fits seamlessly into your WRX GT, GR86, or BRZ's bellhousing, preserving OEM clutch compatibility and requiring no modifications to existing driveline components.

WRX and BRZ owners building street-to-track platforms benefit most from this upgrade, as the reduced inertia transforms how the car feels during spirited driving and autocross runs. Installation requires flywheel removal and basic clutch work, making it a natural pairing with clutch replacement or transmission servicing. Whether you're chasing lap times, improving daily driving feel, or prepping for forced induction, the Flywheel Ultra Light Subaru WRX GT/GR86 BRZ delivers measurable improvements in responsiveness and shift speed that serious Subaru enthusiasts expect.
