Exedy OE 1993-1995 Mazda RX-7 R2 Clutch Kit
The Exedy KMZ01 is a factory-style replacement clutch kit for the third-generation Mazda RX-7, the FD sold in the US and Canada from 1993 to 1995. It is the kit to buy when your FD is stock or close to it and the original clutch is finally worn out: slipping when the second turbo comes in, chattering on takeoff, or grabbing at the very top of the pedal. Our listing names the R2 package, but this is an OE replacement for the manual FD rather than a performance upgrade, so the goal is the pedal feel and engagement the car had when it was new.
The FD runs the 1.3L 13B-REW twin-rotor with sequential twin turbochargers: one turbo works from low rpm and the second joins in the upper rev range. That hand-off sends a sharp rise in torque through the clutch, which is exactly where a tired disc gives up first. The five-speed manual was standard on every US trim, while the automatic was only offered on the base and Touring cars, so this kit applies only to manual cars.
Exedy says its OE Replacement kits are rated for OEM power levels and are designed to work with the original flywheel. That makes KMZ01 the right choice for an unmodified car, or one with mild breathing mods that is not seeing extra boost. If the car has a raised boost setting, a single-turbo conversion or regular track days, a stock-rated clutch will slip again, and an upgrade such as the ACT ZX6-HDSS street kit is the better buy.
Rule out the hydraulics first. A failing slave cylinder, old fluid or air in the line will cause poor release and grinding that a new clutch will not fix. To check for slip, make a fourth-gear pull from about 3,000 rpm under full boost and watch whether the tach moves faster than the speedometer. Our slipping diagnosis guide explains how to read that road test. If the gearbox itself is grinding or whining in specific gears, read rebuild vs replace vs reman before you decide what to fix while it is out. With the gearbox off, look for oil on the flywheel face and the bellhousing; any leak has to be fixed or it will ruin the new disc.
This kit is listed for the 1993, 1994 and 1995 Mazda RX-7 with the five-speed manual. Mazda called the sport package R1 at launch and renamed it R2 for 1994, and the base and Touring cars share the same manual drivetrain. It does not fit the earlier FC RX-7 or the RX-8. Many FDs have been imported, swapped or rebuilt over the years, so if your car is a JDM import or the gearbox has been changed, send us the year and VIN or chassis number and we will match it before it ships.

Exedy says most of its OE Replacement kits include the pressure plate, clutch disc, release bearing, a pilot bearing or bushing, an alignment tool and grease; check the contents against the parts you remove. A flywheel is not part of this kit. For Exedy warranty purposes the flywheel must be resurfaced or replaced, so budget for machining the stock unit. Exedy designs its OE kits around the factory flywheel; if you would rather go lighter, such as a 13.2 lb steel flywheel for the 89-95 RX-7, that is usually paired with a performance clutch rather than this kit. Torque the pressure plate bolts to the factory specification in a crisscross pattern; Exedy recommends thread locker on those bolts. Use a light film of grease on the input splines, inspect the release fork and pivot, and bleed the clutch hydraulics with the fluid named on the reservoir cap. Break it in gently for 500 city miles or 1,000 highway miles with no high-rpm shifts, quick shifts or launches, as Exedy recommends.

It fits the US-market FD with the five-speed manual, including base, Touring and R1/R2 cars. Automatic cars do not use it, and it does not fit the FC or RX-8.
No. Exedy rates its OE Replacement kits for factory power levels. For raised boost or a single-turbo setup, choose a performance kit instead.
Yes. Exedy requires the flywheel to be resurfaced or replaced for warranty, and a fresh surface also prevents chatter on the new disc.
Exedy says most OE kits contain the pressure plate, disc, release bearing, pilot bearing or bushing, alignment tool and grease. A flywheel is not included.
Exedy recommends 500 city miles or 1,000 highway miles of easy driving with no high-rpm shifting, quick shifting or launching.
Inspect the slave cylinder, release fork and pivot, and fix any oil leak at the flywheel. Machining or replacing the flywheel is required.
