The ACT 601140 is an XACT Streetlite flywheel for the Mazda MX-5 Miata. It is considerably lighter than the factory flywheel and is the most durable flywheel offering in the ACT lineup, with material properly distributed for maximum strength, lower rotating inertia, good heat tolerance, and rigidity. The flywheel is recommended for street and race use and is fully serviceable, meaning it can be resurfaced without purchasing additional parts.
