Fidanza Upgraded Aluminum Flywheel Kit For 2013-2015 Scion FR-S & Subaru BRZ strut bars Perrin 07-21 STI EJ EnginesWhether it be in overall balance, critical clearances or improved design, our flywheels are built for performance. Machined from the highest quality 6061 T6 or 2024 T3 aluminum, each flywheel is manufactured to deliver optimum tensile strength, heat dissipation and weight reduction, without going too light and causing poor idle and driving issues like some of the ultra lightweight competitors. We aren't always the lightest, but we are the best!
