The ACT 600145-02 is an XACT Streetlite flywheel built for Mazda RX-7 rotary applications and ships complete with the ACT CW02 counterweight required for installation. Streetlite flywheels are considerably lighter than the factory unit while remaining the most durable flywheel in the ACT lineup, with material properly distributed for strength, lower rotating inertia, good heat tolerance, and rigidity. The flywheel is preferred for street or drag racing use and is fully serviceable, meaning it can be resurfaced without buying additional parts.

FAQ
Does this flywheel include the counterweight needed for installation?
Yes. The 600145-02 kit includes the ACT CW02 counterweight required when installing an XACT flywheel on Mazda RX-7 rotary applications, so no separate purchase is needed.
What is a flywheel step, and why does it matter?
The flywheel step is the distance between the friction surface and the pressure plate mounting point, and it determines the proper working range of the pressure plate. Depending on the application it can be an up step, down step, or flat (zero step), so it should always be checked against the vehicle's specification.
Can this flywheel be resurfaced?
Yes. It can be resurfaced like a stock flywheel using a flywheel grinder, removing no more than 0.040 in (1.02mm) of material total while maintaining the correct flywheel step.
Does this flywheel fit both the FC and FD generation RX-7?
Yes, this kit covers the 1989-1991 Turbo (FC) RX-7 as well as the 1993-1995 North American and 1996-2002 JDM/Euro FD RX-7, all using the ACT CW02 counterweight. Confirm the exact year and trim against the Vehicle Applications list above.
