Frequently Asked Questions

What is the T2S-F12?

It is the ACT multi-disc clutch kit 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?

ACT lists this organic kit for street or street/strip use with a matched drivetrain setup.

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.

Compare street-oriented and competition configurations for compatible domestic and import manual-transmission builds, including modified engines that require additional clutch capacity. Twin-Disc and Triple-Disc Clutch Systems Multi-disc clutches use multiple friction discs within a matched assembly to provide additional working friction surfaces. This gives manufacturers another way to achieve torque capacity without relying solely on a larger single disc or increased clamping force. Disc count alone does not determine capacity, pedal effort, or street manners. Compare friction material, disc diameter, pressure-plate design, and the manufacturer’s intended use.
