ACT 1990 Mazda Miata P/PL Heavy Duty Clutch Pressure Plate | MZ012

This pressure plate features an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All ACT diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's Heavy Duty pressure plates increase clamp load by 20 to 50 percent. The Heavy Duty pressure plates are recommended.

Use ACT manufacturer part number MZ012 to confirm the exact drivetrain component and application.

Frequently Asked Questions

What is the MZ012?

It is the ACT clutch pressure plate described in this listing for the stated application and use.

How do I confirm fitment?

Match the complete year, make, model, engine, transmission and every qualifier shown in the title and fitment section.

Is this intended for street use?

Use suitability depends on the specific disc, pressure plate, flywheel and clutch configuration shown in the listing.

Can I mix clutch components from different kits?

Do not assume components are interchangeable. Verify spline, diameter, step height, release system and the complete matched ACT assembly.

Does installation require break-in?

Follow the current ACT instructions for the exact clutch and disc type. Street friction systems commonly require a controlled break-in period; race products can differ.

Should the flywheel be inspected or resurfaced?

Yes. Inspect the mating surface and use only a compatible flywheel prepared to ACT specifications. Replace damaged or out-of-spec components.

Is professional installation recommended?

Yes. Clutch and flywheel work requires correct transmission removal, fastener torque, alignment, release-system setup and safety procedures.

Can Black Ops Auto Works help verify the application?

Yes. Provide the vehicle, engine, transmission, existing flywheel, power level and intended street or competition use before ordering.

Installation Instructions

  1. Confirm ACT part and the complete engine, transmission, flywheel, spline, and release-system application before disassembly.
  2. Inspect every component and compare the new part with the removed assembly before modifying or installing anything.
  3. Inspect the flywheel or friction surface, pilot support, release bearing, fork, pivot, hydraulic system, seals, and mounting hardware.
  4. Clean friction surfaces correctly and keep oil, grease, and fingerprints away from the clutch disc and mating faces.
  5. Use the vehicle service procedure and current ACT instructions for alignment, fasteners, torque sequence, release travel, and clearances.
  6. Verify smooth release, correct free play, clean gear engagement, and leak-free operation before road use.
  7. Complete the manufacturer-specified break-in procedure before launches, dyno pulls, racing, towing, or full-torque operation.

Mazda Miata Parts and Accessories

Choose Mazda Miata gauge mounts and engine accessories by generation, interior layout and installed engine. A-pillar pods and crankshaft dampers have very different application requirements. Gauge Pods and Interior Mounting Compare the model-year range, pillar shape and gauge count. Single, dual and triple pods provide different arrangements; 52mm and 2-1/16-inch references still require the exact gauge and mount dimensions to agree. Review attachment instructions, wiring clearance and the interior safety equipment before installation. The pod is a mounting component and should not be assumed to include gauges or sensors. Crankshaft Damper Configuration For a 1.8L damper application, compare belt grooves, pulley alignment and the trigger-wheel arrangement. Options described with and without an OEM trigger wheel require separate selection. Confirm whether the stated belt guide is included and which existing components must be retained. An engine conversion needs review against the ac...

Mazda MX-5 Miata Parts and Accessories

Explore Mazda MX-5 Miata intake, exhaust and brake options by generation and engine. Keep earlier 1.8L damper configurations separate from later 2.0L intake and chassis applications. Intake and Axle-Back Exhaust Choices Compare an intake’s exact year and engine coverage, heat-shield contents and sensor connections. Polished and black finishes should be compared only after the underlying part application is established. For a single-exit axle-back exhaust, check rear-section connections, outlet position, material and supplied hardware. Confirm clearance and compatibility with the existing exhaust and body configuration. Dampers and Brake-Service Details Damper selection depends on crankshaft application, belt grooves, pulley alignment and trigger-wheel configuration. A 1.8L damper reference is not a substitute for identifying a later 2.0L engine’s drive arrangement. Match rotor geometry and caliper package separately at each axle. For a brake hose, identify left/right and front/rear ...
