Frequently Asked Questions
Will this Competition Clutch part fit my 2008 Mitsubishi Lancer Evolution GSR?
That application is listed, but confirm the exact part number, engine, transmission, input-shaft spline, flywheel requirement, clutch stage, disc type, and every manufacturer note before ordering.
Should the flywheel be inspected or replaced with a new clutch?
Yes. Inspect the flywheel for heat damage, cracks, runout, and the correct step or friction surface. Resurface or replace it only according to the clutch and flywheel manufacturer's specifications.
Is a clutch break-in period required?
Follow the current instructions for the exact clutch. Many street friction materials require controlled engagement cycles before full-torque use, while some race systems have different procedures.
Installation Instructions
Follow the current Competition Clutch and factory service instructions for this exact part number. Verify every interface before transmission removal, inspect and measure the flywheel and release system, replace worn seals and bearings, keep friction surfaces clean, use the specified fasteners and torque sequence, bleed hydraulic components, confirm release travel, and complete the required break-in procedure before full-torque use.

Shop clutch kits, flywheels, replacement discs and release-system components at Black Ops Auto Works. Compare ACT, Clutch Masters, Competition Clutch, Exedy, McLeod, XClutch, Action Clutch and other listed choices for a street refresh, a modified daily driver or a dedicated competition build. Choose the complete system around engine torque, use and the installed transmission.Street Engagement and Torque CapacityOrganic street-oriented discs, performance friction materials and different pressure-plate designs offer different engagement and pedal characteristics. Compare the actual manufacturer torque rating and its stated measurement basis with your build, including planned changes.A stage number is a manufacturer’s product-family label, not a universal horsepower range. An Action Clutch Stage 1 or Stage 2 reference, an ACT HD/Performance Street combination and a Clutch Masters FX-series kit must each be compared by their own specifications. Higher stage does not automatically mean a...

Shop Competition Clutch components for clutch replacement, drivetrain upgrades and existing-system service at Black Ops Auto Works. Compare stock-replacement and staged kits, White Bunny packages, selected twin-disc systems, flywheels and replacement discs. Choose capacity and friction configuration around actual torque and driving priorities.Stock Replacement and Staged KitsChoose the clutch for the torque it must hold and the way the vehicle is driven. Compare stock-replacement, Stage 1 Gravity and Stage 1.5 full-face organic references with Steelback Brass Plus, segmented-ceramic and six-pad ceramic designs. The current Focus ST Stage 2 listing uses a full-face organic description, so stage labels should not replace the exact friction specification. Sprung and rigid versions also appear separately. Review the complete kit’s engagement, pedal and capacity information rather than treating the highest stage as the best daily-driving choice.White Bunny and Multi-Disc PackagesCompare ...

Compare ACT Streetlite and Prolite designs, Fidanza aluminum options, Action Clutch, Clutch Masters, SPEC, XClutch and other listed references. Choose the clutch and transmission arrangement first, then balance engine response, everyday driving and service requirements.Flywheel Response and Driving CharacterRotational inertia affects how readily engine speed changes. A lower-inertia flywheel can create a more responsive feel, while a design retaining more inertia can suit different launch, low-speed or load demands. Compare the complete design and intended use rather than choosing the lightest advertised weight automatically.ACT Streetlite is aimed at performance street and drag-racing applications, while Prolite emphasizes lower inertia for road and rally racing with possible idle or gear-noise tradeoffs. Choose the supported application and driving character you wa...
