Clutch Masters 94-04 Mazda Miata 1.8L FX250 Clutch Kit
Clutch Masters 10905-HD0F is the FX250 clutch kit for the 1.8L Mazda Miata MX-5, listed by us for 1994-2004. It is the right pick for a mostly stock or lightly modified NA or NB Miata that sees canyon runs, autocross weekends or an aggressive driver, where a plain replacement clutch wears out early but a ceramic or high-clamp kit would make traffic miserable.
The FX250 is a hybrid disc. Clutch Masters puts Fiber-Tough friction on the side that faces the pressure plate and steel-backed organic friction on the flywheel side, then mounts it on a heavy-duty sprung hub with a marcel spring wafer. It works with the Power Plus I heavy-duty pressure plate and is rated at a 110 percent increase in holding capacity. The organic flywheel face and marcel wafer are what keep engagement soft and progressive, so the Miata keeps the light, easy pedal feel it is known for. Clutch Masters positions it for the spirited street driver or weekend racer who abuses the car occasionally. If the car runs a turbo or supercharger kit, step up to the 10905-HDFF FX350, which is full Fiber-Tough and built for medium boost.
On a Miata, the hydraulics are a frequent culprit. Check the clutch master and slave for leaks, bleed the system and make sure the pedal returns fully. Look for oil from the rear main or input shaft seal, which contaminates a disc. If those check out, a high-gear, low-rpm, full-throttle test that shows rpm rising faster than speed confirms slip. Our slipping diagnosis guide lays out the steps. If the hydraulics are tired, the Miata clutch master and slave cylinder kit is worth doing while the car is apart.
Our listing reads 1994-2004 Mazda Miata 1.8L. Clutch Masters lists 10905-HD0F for the Miata MX-5 1994-2005 1.8L, so a 2005 car is on the maker list; send us your VIN and we will confirm it. The 1990-1993 1.6L cars use a different flywheel and clutch and only take this kit after a 1.8L engine and flywheel swap. The 2006-up NC 2.0L uses its own kits. Send your year, VIN and engine if anything has been changed.

Not as delivered. Clutch Masters lists it for 1.8L cars only. A 1.6L car needs a 1.8L engine and flywheel conversion before this kit will fit.
It is designed for spirited street and occasional track use. For a medium-boost turbo or supercharger setup, Clutch Masters points buyers to the FX350, 10905-HDFF.
The FX250 uses a heavy-duty pressure plate, but the hybrid disc with an organic flywheel side and marcel wafer is built to stay street friendly, closer to stock feel than the higher FX kits.
A flywheel is not included. The stock one must be resurfaced flat, or you can install a lightweight steel flywheel for the 1994-2005 1.8L at the same time.
The Miata clutch hydraulics use brake fluid. Bleed with the type printed on the reservoir cap after the install.
Clutch Masters lists 1994-2005 1.8L. Our listing reads 1994-2004, so send us your VIN for a 2005 and we will confirm before shipping.
