Designed for Street and Track Applications: The Spec Billet Steel Flywheel is specially tuned to perform based on how each specific application reacts to changes in rotational mass. This ensures that the flywheel is able to deliver maximum performance. Additionally, the flywheel is precision-machined to deliver perfect balance. Furthermore, the steel construction is ideal for street applications as they lose fewer RPMs when shifting. Aluminum SPEC flywheel is 14 pounds compared to 25 pounds for this steel SPEC version.

Precision-Machined Billet Steel: The Spec Billet Steel Flywheel is machined to the tightest tolerances at .001 machine tolerance. This ensures a flat seating surface for the smoothest rotation. Additionally, the high-quality steel ensures strength, toughness, and durability for long service.

SFI Certified: All Spec flywheels are SFI Certified to exceed high-speed racing safety standards. This gives you confidence that the flywheel will not fail catastrophically when pushing your Mustang to its limit.
