ACT 1987 Mazda RX-7 HD/Perf Street Sprung Clutch Kit
ACT Z65-HDSS is the clutch many FC RX-7 Turbo owners put in when the original is worn out or starting to slip after mild boost and exhaust upgrades, and they still want the car to drive like a road car. It covers the 1986 through 1991 RX-7 Turbo with the 13B turbo rotary. The kit combines ACT's Heavy Duty pressure plate with its Performance Street organic disc, so you get noticeably more holding power with engagement that stays close to factory.
Z65-HDSS uses the MZ010 Heavy Duty plate and the 3000204 Performance Street sprung disc. The disc is a full organic face with high copper content for heat transfer and a steel-backed lining for burst strength, and ACT uses reduced marcel so shifts are quicker than with the stock disc. The spring hub keeps takeoff smooth. ACT's figures:
That 34 percent margin suits a healthy turbo car with intake, exhaust and modest boost. For big turbos or track abuse, the Z65-HDG6 keeps the same plate with a six-pad ceramic disc, and the Z65-XTSS keeps an organic disc behind the stiffer Xtreme plate.
Check the clutch fluid level and bleed the system, since aged fluid and tired hydraulics on an FC can mimic clutch problems. Then do a roll-on in a high gear at low rpm; if engine speed rises faster than the car, the disc is slipping. Oil around the bellhousing points to a leaking rear seal that needs fixing at the same time or the new disc will be contaminated. Our slipping diagnosis guide has the full checklist, and manual vs. automatic repair cost gives an idea of the labor.
The listing title says 1987. ACT's fitment table covers the RX-7 Turbo from 1986 to 1991, plus the 1988 10th Anniversary model, all with the 1.3L turbocharged rotary. It is not listed for the naturally aspirated FC, and the FD third generation uses different ACT kits. If your car is an NA-to-turbo conversion or has a swapped gearbox, measure the old disc or send us the year and VIN before ordering. More kits are on our rebuild kits page.

ACT lists the 1986-1991 RX-7 Turbo with the 13B turbo, including the 1988 10th Anniversary. It is not listed for the non-turbo FC or the FD.
ACT rates it at 330 ft-lb at the crank, 34 percent over the stock clutch. Bigger builds should look at Z65-HDG6 or Z65-XTSS.
Yes. ACT lists light to moderate pedal effort and smooth engagement with an organic disc, which is why it is a common street choice.
Neither is included. Resurface your flywheel, or buy an ACT XACT flywheel along with the CW02 counterweight; the 600145-02 kit includes both.
ACT recommends 300 to 500 miles of mild engagement, such as city driving, before racing or spirited driving.
