$ 2,250.00 $ 1,823.00

ACT T1RS-S01 HD Sprung Race Twin Clutch | WRX 2006–2026

ACT T1RS-S01 is a matched 225 mm sprung-hub twin-disc clutch assembly with Heavy Duty pressure plate and ceramic race friction material for the manual-transmission applications below.

Use ACT manufacturer part number T1RS-S01 to confirm the exact drivetrain component and application.

Key Features

  • Matched flywheel and twin-friction-plate assembly with sprung Mono-Drive hub.
  • Ceramic friction plates for racing.
  • Verify the complete engine, transmission and flywheel configuration before installation.

Fitment

Years Make Model Application
2006-2014 Subaru Impreza WRX / WRX EJ255 / listed EJ257 2.5L turbo; five-speed manual; excludes STI TY856
2015-2021 Subaru WRX 2.0L turbo FA20; six-speed manual; excludes CVT
2022-2026 Subaru WRX 2.4L turbo FA24; six-speed manual; excludes CVT/SPT
2006 Subaru Baja Turbo 2.5L turbo EJ255; manual
2006-2008 Subaru Forester XT 2.5L turbo EJ255; manual
2005-2012 Subaru Legacy GT 2.5L turbo EJ255; TY757/TY758 five-speed or TY756 six-speed manual
2006 Subaru Legacy GT spec.B Five-speed manual only; excludes 2007-2009 TY856 spec.B
2005-2009 Subaru Outback XT 2.5L turbo EJ255; manual

Vehicle fitment is a starting point. Confirm every drivetrain specification and the exact ACT part number before installation.

ACT's product-page fitment table also lists 2007-2009 Legacy GT spec.B, but its application chart assigns the TY856 six-speed spec.B to the S05/S07 kits. That conflicting application is excluded here pending ACT confirmation; the 2006 five-speed spec.B remains listed.

Frequently Asked Questions

What is the T1RS-S01?

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?

This listing contains a race-oriented or not-for-street-use designation. Follow ACT’s stated use and drivability guidance.

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.
