Exedy 16-18 MX-5 Miata 2.0L 6sp. Skyactive Stage 1 Clutch Kit
If your 2016, 2017 or 2018 ND MX-5 Miata is starting to slip in the upper gears, engaging high on the pedal, or you have added intake, tune or a supercharger and want a clutch with more margin, Exedy 10814 is a Stage 1 organic kit made for the 2.0L Skyactiv-G and six-speed manual in those first ND years. It is the closest thing to a stock clutch that still gives you more holding power, which makes it a sensible replacement for a daily-driven or autocross car.
The early ND uses a single-disc dry clutch bolted to a single-mass flywheel, released by a hydraulic slave and release bearing. Exedy's Stage 1 line keeps an organic friction facing, so engagement stays progressive, but uses a pressure plate with higher clamp load and a disc damper upgraded to handle more torque. Exedy says Stage 1 organic kits drive similar to the OEM clutch, with pedal effort typically 20 to 35 percent higher depending on the application. Expect a slightly firmer pedal, not an on-off race clutch. If you are building serious boost, a heavier-duty kit such as the ACT ZM10-HDSS for the 2016-18 ND, which comes with its own flywheel, is the step up.
Do a roll-on test: in 4th gear at about 2,500 rpm, go to full throttle and watch the tach. If engine speed jumps ahead of road speed, the disc is slipping. Before blaming the clutch, check the clutch fluid level and look for leaks at the slave cylinder, and look for oil at the bellhousing seam, since a leaking rear main seal can contaminate a new disc. A soft pedal or a clutch that will not release usually points to hydraulics, not the friction parts. Our slipping diagnosis guide covers the test in detail, and the clutch slipping causes guide explains what else can cause it.
Our listing covers the 2016-2018 Mazda MX-5 Miata with the 2.0L engine and six-speed manual, which matches the year range the kit is built for. It is not for 2019 and later cars: for the 2019 model year Mazda replaced the single-mass flywheel with a low-inertia dual-mass flywheel along with the power increase, so later cars are a different clutch application. If you own a 2019-up ND, look at the ACT ZM14 kit for 2019-25 cars instead. The 2017-2018 RF uses the same 2.0L drivetrain, but if your car has been swapped, has an aftermarket flywheel, or you are unsure of the build date, send us the year and VIN and we will confirm.

No. The kit is for 2016-2018 cars. Mazda changed the 2019 MX-5 to a dual-mass flywheel along with the power upgrade, so later cars need a different clutch.
No. Exedy designs its Stage 1 kits to work with the OEM flywheel. Have the stock flywheel resurfaced, or replace it if it shows cracks, hot spots or heavy wear.
Exedy says Stage 1 kits typically raise pedal effort by 20 to 35 percent depending on the car. It drives much like the factory clutch, just a little firmer.
A pressure plate, organic clutch disc, release bearing and pilot bearing. Exedy uses OEM-supplier bearings in its single sport kits.
It suits stock and lightly modified cars, plus street and light track use. For a high-boost build, step up to a heavier-duty kit rated for more torque.
The MX-5 clutch shares the brake fluid reservoir, so bleed it with the DOT 3 or DOT 4 fluid shown on your reservoir cap after the install.
