This product is a 6-pad spring-centered race discs made with high quality ceramic friction materials. The engagement is harsher, but shifting is faster. The heavy duty torsional dampening springs are stronger, in most cases, than standard springs and are provided in the best sizes and spring rates to suit the application. The 6-pad, spring-centered disc is recommended for larger clutch sizes to absorb more heat and for smoother.

The exact ACT clutch disc and quantity identified by the product title and MPN. Bearings, alignment tools, flywheel bolts, pressure-plate bolts, hydraulic parts, and related hardware are included only when specifically stated.
ACT develops application-specific clutch kits, friction discs, pressure plates, flywheels, bearings, and supporting drivetrain components for street and motorsport use. Black Ops Auto Works organizes every ACT listing by exact MPN and verified vehicle application.
The 6240618 should be selected as part of a complete matched ACT drivetrain system.
What is the 6240618?
It is the ACT clutch disc 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.

Shop Subaru Impreza cabin accessories and exhaust applications by exact generation, body and trim. Separate non-WRX vehicles from WRX/STI applications before comparing systems or exterior fit. Body and Interior Coverage Hatchback deflectors require the correct window layout and exact trim coverage. Some displayed references explicitly exclude WRX/STI, while others name those trims. Floor liners need matching contours, retention points and front/second-row coverage. Shared Outback, Legacy or Crosstrek naming does not establish every Impreza cabin application. Exhaust Configuration and Contents AWE GV/VA sedan references require the specified chassis, engine and body. Do not extend sedan exhaust coverage to another body or a non-turbo Impreza. Touring, Track and conversion kits are different choices. Compare sound requirements and whether the listing supplies a complete exhaust or components for an existing compatible system.

Shop Subaru Legacy floor protection and accessory applications by exact generation and engine. Compare front/second-row coverage and current equipment before selecting shared Outback references. Floor Coverage by Generation Combined cabin packages differ from second-row-only liners. Match exact production, contours, retention points and the supplied pieces. A shared Legacy/Outback title needs the specific year and floor-layout application confirmed. Earlier-generation liners should not be extended to a newer cabin by model naming alone. Lighting and Engine Accessories Fog-light pocket kits require matching bumper geometry, brackets and wiring. Confirm the exact kit application and installation contents. A BRZ-led damper reference needs the correct Legacy engine and supported adapter combination. Pedal controllers separately require exact vehicle and connector coverage.
