Introduction

2002-2018 Subaru WRX/STI Aluminum Flywheel by Spec

SPEC aluminum flywheels are CNC machined and exceed SFI standards for high stress racing applications. These units are recommended for highly modified street or racing vehicles, and for mildly modified street cars that can benefit from reduced rotating mass without the loss of daily drivability. The body of the flywheel is made of tempered aluminums, either 6061 T6 or 2024 T3, for ultimate strength and lightest possible weight. The 1/4 inch thick friction plate is a 1050 high carbon alloy, for incredible durability with any friction disc material, even iron. The plates are secured to the body by aerospace fasteners. The ring gears are pressed on and secured with grade 10 fasteners. The gear is also heat treated for longevity.
