ACT 1989 Mazda RX-7 Flywheel Kit Streetlite w/CW02
ACT 600145-02 is the flywheel half of a rotary clutch job for the late FC RX-7 Turbo and the FD RX-7. You get ACT's XACT Streetlite chromoly flywheel and the CW02 rear counterweight that a 13B needs whenever the factory flywheel comes off, so the engine stays in balance and the clutch has a fresh, flat face to work against. Owners usually land here because a worn stock flywheel is chattering, the face is glazed or cracked, or they want the engine to rev more freely without the noise of a full race flywheel.
On a piston engine the flywheel is mostly a friction surface and a ring gear. On the 13B rotary it is also part of the rear balance of the eccentric shaft, which is why ACT says a counterweight is required whenever an XACT flywheel goes on an RX-7 or RX-8. The CW02 is a 4.1 lb machined steel piece that bolts on with the flywheel and carries the imbalance the factory flywheel used to provide. ACT says it reduces load on the engine bearings, which on a rotary is not something to gamble with.
The Streetlite itself is forged chromoly, CNC machined and computer balanced, with a 240 mm (9.4 in) friction face and an induction-hardened 125-tooth ring gear. ACT lists it at 17.5 lb and certifies it to SFI 1.1. ACT describes the feel as noticeably quicker response and acceleration with OE to mild gear rattle, and calls Streetlite its most durable flywheel, preferred for street and drag use. That makes it the sensible choice for a twin-turbo FD that still sees traffic and a daily commute.
Most flywheel problems are found during a clutch replacement, so plan the two jobs together. Slipping under boost is usually the disc, and a soft or sinking pedal is often the hydraulics, so rule those out first. Our slipping diagnosis guide covers the road test that separates clutch slip from other drivetrain faults, and our manual vs automatic repair cost breakdown helps you budget labor. With the gearbox down, check the face for heat checking and measure for runout before deciding to resurface or replace.
Our listing names the 1989 RX-7. ACT's fitment table for 600145-02 covers the 1989, 1990 and 1991 RX-7 Turbo (FC) and the 1993, 1994 and 1995 FD RX-7 in Base, R1, R2 and Touring trims, plus JDM and European FD cars through the late 1990s. ACT does not list the naturally aspirated FC or the 1986-1988 Turbo for this kit. The RX-8 uses a different counterweight and is covered by the 600145-03 kit. Rotary cars are often swapped and rebuilt, so if you are not sure which engine and counterweight your car has, send us the year and VIN before you order.

ACT lists the 1989-1991 RX-7 Turbo and the 1993-1995 FD RX-7, plus JDM and European FD cars. It is not listed for the non-turbo FC or 1986-1988 Turbo.
Yes. The kit is the 600145 Streetlite flywheel plus the CW02 counterweight. ACT says the counterweight is required with an XACT flywheel on the rotary.
ACT lists the Streetlite at 17.5 lb with a 240 mm friction face and 125-tooth ring gear. The CW02 counterweight is listed separately at 4.1 lb.
ACT rates the Streetlite at OE to mild gear rattle, which is why it is recommended for street and drag cars rather than only track use.
No. The RX-8 uses a different counterweight. Choose ACT 600145-03 with CW03 for 2004-2011 RX-8s.
Yes. ACT allows normal resurfacing, removing only what is needed and never more than 0.040 in, while keeping the correct step.
