05-09 Legacy GT 5 Speed Lightweight Flywheels

A lightweight flywheel is a great addition to any car, and even more so on turbocharged applications. A lighter flywheel drastically reduces the rotating mass attached to your crankshaft, allowing your car to rev and accelerate faster. On a turbocharged car like 05-09 Legacy GT, faster revs mean a quicker turbo spool to get you into that 'sweet spot' faster.


SPEC Aluminum Flywheel

SPEC aluminum flywheels are CNC machined and exceed SFI standards for high stress racing applications. The SPEC lightweight flywheels are recommended for highly modified street or racing vehicles. The body of the flywheel is made of tempered aluminum, 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. They gear is also heat treated for longevity.
