ACT 1993 Mazda RX-7 XT-M/Race Sprung 6 Pad Clutch Kit
The ACT ZX6-XTG6 is the heaviest-duty single-disc kit ACT makes for the third-generation FD Mazda RX-7, the 1993 to 1995 twin-turbo 13B car in the US. It is built for FDs that have gone single turbo or are making serious boost, where a stock-style clutch slips the first time the turbo comes on hard. If your car is a mild street build, this is more clutch than you need; if it sees drag strip launches or track time, it is the one to look at.
ZX6-XTG6 pairs ACT's Xtreme pressure plate with a six-pad, spring-centered ceramic race disc. ACT rates it at 575 ft-lb at the crank, 103 percent over the original clutch, using a 240 mm (9.4 in) disc on a 1 in input spline. The six pads give more friction area and heat capacity than a four-pad puck disc, and the sprung hub damps the driveline shock that a rigid race disc would send straight into the five-speed.
The FD uses a pull-type release system, and this kit includes ACT's Monoloc, a one-piece hardened chromoly retainer that replaces the factory two-piece wedge collar and wire ring between the release bearing and pressure plate. ACT says it keeps the bearing evenly loaded and aligned and greatly extends release mechanism life, which is a known weak point when clamp load goes up. Kit contents per ACT: MZ028X Xtreme pressure plate, 6240508 six-pad sprung race disc, RB600 release bearing, PB1013 pilot bearing and AT03 alignment tool. No flywheel is included.
Boost leaks and failing sequential turbo control are common on FDs and can feel like lost power, so prove slip first: in fourth gear, go to full throttle from low rpm and watch whether rpm rises faster than road speed. Check the clutch fluid and slave cylinder, and look for oil at the bellhousing, which can come from the rear main seal and glaze any disc. Our slipping diagnosis guide covers the checks, and the rebuild versus replace guide helps if the gearbox itself is also suspect.
Our listing is titled for the 1993 RX-7. ACT's application chart 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 models through 1998. Every FD uses the 13B rotary, which needs a counterweight on the flywheel. Confirm your car has not had a different flywheel or clutch conversion fitted, and send us your year and VIN if you want us to double-check. More kits are in our rebuild kits category.
For a street car with a smoother take-up, compare the ZX6-XTSS organic street kit or the lighter-pedal ZX6-HDSS.

Yes. ACT lists it for the US 1993 to 1995 FD RX-7 in all trims, plus JDM and Euro FD models. Our listing title says 1993 because that is the first year of the application.
For most owners, yes. The six-pad ceramic disc engages harder and ACT expects 50 to 80 percent more pedal effort with an Xtreme plate. Street-driven FDs usually do better with the ZX6-XTSS or ZX6-HDSS organic kits.
The FD uses a pull-type clutch. Monoloc is ACT's one-piece retainer that replaces the factory wedge collar and wire ring, keeping the release bearing aligned and loaded evenly so the clutch releases reliably under a stiffer pressure plate.
The kit does not include a flywheel. You can resurface the stock one or fit an ACT XACT flywheel, which requires the CW02 counterweight on the rotary engine. The 600145-02 kit includes both.
ACT rates the ZX6-XTG6 at 575 ft-lb at the crank, 103 percent over the factory clutch.
