ACT 1993 Mazda RX-7 XT-M/Perf Street Sprung Clutch Kit
The ACT ZX6-XTSS is the street-friendly way to put serious clamp load into an FD Mazda RX-7. It combines ACT's Xtreme pressure plate with an organic Performance Street sprung disc, so a 1993 to 1995 twin-turbo 13B car with bolt-ons, a boost increase or a single-turbo conversion stops slipping without the harsh, on-off engagement of a puck disc. If you drive your FD on the street most of the time but it now makes more power than the factory clutch can hold, this is the kit to compare first.
ACT rates ZX6-XTSS at 450 ft-lb measured at the crank, 59 percent more than the original clutch, on a 240 mm (9.4 in) organic disc with a 1 in input spline. The Xtreme diaphragm raises clamp load and reduces deflection, while the sprung organic disc engages smoothly and damps driveline shock. ACT describes the feel as moderate to heavy pedal effort with smooth, positive engagement and OE to mild gear rattle, and recommends it for street and race use.
The FD's clutch is pull-type, and this kit comes with ACT's Monoloc: a one-piece hardened chromoly retainer that replaces the factory two-piece wedge collar and wire ring that holds the release bearing to the pressure plate. ACT says Monoloc loads the bearing and pressure plate evenly so they stay aligned, which is why a stiffer plate does not wear out the release mechanism. Per ACT the kit contains the MZ028X Xtreme pressure plate, 3000206 Performance Street sprung disc, RB600 release bearing, PB1013 pilot bearing and AT03 alignment tool. A flywheel is not included.
On an FD, rule out boost and turbo control problems before blaming the clutch, since a leak or a sequential system fault feels like lost power. A true slip test is full throttle from low rpm in fourth while watching whether rpm climbs faster than speed. Check the clutch fluid level and the slave cylinder, and look for oil at the bellhousing that could ruin a new disc. Our slipping diagnosis guide covers the process, and the manual transmission repair cost guide helps you budget the job.
Our listing names the 1993 RX-7. ACT's application chart for ZX6-XTSS covers the US 1993 RX-7 Base, R1 and Touring and the 1994 to 1995 Base, R2 and Touring, plus JDM FD models through 2002 and Euro FD models through 1998. It does not fit the earlier FC RX-7. If the car has had a different flywheel or a clutch conversion, confirm what is in it before ordering, or send us your year and VIN. ACT's harder-gripping option is the ZX6-XTG6 six-pad race kit, and the lighter-pedal choice is the ZX6-HDSS. More kits are in our rebuild kits category.

Yes. ACT lists it for the US 1993 to 1995 FD RX-7 in Base, R1, R2 and Touring trims, plus JDM and Euro FD models. Our title says 1993 because that is the first US year.
ACT rates it at 450 ft-lb at the crank, 59 percent over the factory clutch.
Yes. The organic sprung disc engages smoothly like a stock clutch. The Xtreme plate still raises pedal effort, which ACT describes as moderate to heavy.
No. Resurface your stock flywheel or fit an ACT XACT flywheel, which requires the CW02 counterweight on the rotary; the 600145-02 kit includes both.
ACT's one-piece chromoly retainer for pull-type clutches. It replaces the factory wedge collar and wire ring and keeps the release bearing aligned and evenly loaded.
