600145-01 is a flywheel kit for various Mazda RX-7 and RX-8 applications and comes complete with an ACT counterweight. The flywheel counterweight is required when installing the XACT flywheel on various Mazda RX-7 and RX-8 rotary applications. ACT XACT Streetlite flywheels are considerably lighter than stock and are the most durable flywheel offering from ACT. Materials are properly distributed for maximum strength, lower inertia, good heat tolerance and rigidity. ACT's Streetlite flywheels are preferred for street or drag racing. XACT flywheels are serviceable and can be resurfaced with no need to purchase additional parts.

Frequently Asked Questions

Can I use an aftermarket flywheel with an ACT clutch?
The ACT clutch system is designed to work with both stock and good quality aftermarket flywheels. Inferior aftermarket flywheels may have trouble with warpage or high wear. When replacing a flywheel, be sure that the new flywheel meets the same specifications, such as proper step, ring gear tooth count, flywheel thickness, ring gear offset, etc. If the ACT clutch is designated as part of a conversion kit, then it must be used with only the corresponding ACT flywheel.
What is a flywheel step?
The flywheel step determines the proper working range of the pressure plate and is extremely crucial for the clutch to work properly. The step is the distance between the friction surface and the pressure plate mounting point on the flywheel. Depending on the make and model of the car it can either be an UP step or DOWN step and sometimes the flywheel will be flat (zero step). Check the manufacturer's specifications about the proper flywheel step for the application.
Can the XACT Flywheels be resurfaced, and is there a special process?
Yes, ACT XACT flywheels can be resurfaced just like a stock flywheel and there is no special process other than using a flywheel grinder in good condition to remove as little material as possible for full cleanup (no more than 0.040” / 1.02mm may be removed). Make 100% sure that the proper flywheel step is maintained as this will affect the clutch function if incorrect.
