EXEDY Clutch Kit With Fidanza Aluminum Flywheel for Honda and Acura K-Series

Critical fitment distinction

The clutch portion appears to be based on the EXEDY KHC10, which is normally associated with RSX Type-S and Civic Si applications. The broader RSX Base, Accord and TSX compatibility depends on the included Fidanza conversion flywheel.

Fidanza part 191471 is commonly cataloged for the RSX/Civic Si K-series platform and is designed for an RSX Type-S-style clutch. Confirm that 191471 is actually the flywheel supplied before using that number in the published specifications. Fidanza 191471 application information

The 2002–2006 RSX Base normally uses a different clutch arrangement. This bundle may fit the Base only because the replacement flywheel converts it to the Type-S clutch pattern.

What comes in the kit?

The advertised package includes:

• Fidanza 6061-T6 billet-aluminum flywheel
• EXEDY pressure plate
• EXEDY organic clutch disc
• Release or throwout bearing
• Pilot bushing
• Clutch alignment tool
• Installation guide

Published specifications

There is a small specification conflict worth resolving: some KHC10 references list the HCD823 disc at approximately 213 mm, while this package advertises 215 mm. Confirm the clutch and flywheel part numbers rather than relying on the rounded diameter.

How the EXEDY clutch behaves

This package uses a full-face organic clutch rather than a ceramic puck disc. That generally provides:

• Smooth engagement
• Predictable street manners
• Manageable pedal effort
• Easier low-speed modulation
• Less chatter than a racing clutch
• Performance appropriate for stock or lightly modified engines

No verified torque rating is included in the listing. Owners with turbocharged, supercharged or heavily tuned K-series engines should request a documented crank-torque capacity before ordering.

For help selecting the appropriate friction material, read the Pro Street performance clutch guide.

Fidanza aluminum flywheel benefits

The Fidanza flywheel uses a billet-aluminum body with a replaceable steel friction surface. Reducing flywheel mass allows the engine to change speed more quickly.

Potential benefits include:

• Faster throttle response
• Quicker rev matching
• Reduced rotating mass
• Faster engine-speed changes between shifts
• More responsive autocross and track performance
• Replaceable friction surface for future clutch service

The tradeoffs may include:

• Faster rpm drop between shifts
• More careful throttle control during takeoff
• Additional drivetrain or gear rollover noise
• Reduced low-speed smoothness
• Increased tendency to stall
• Less stored rotational energy when starting uphill

A lightweight flywheel does not meaningfully increase peak horsepower. It reduces rotational inertia, making the engine feel more responsive. Physics remains annoyingly resistant to horsepower stickers.

Hondata requirement for later K24 models

The seller states that 2009–2014 TSX and 2012–2015 Civic Si applications should use a Hondata Pro Flash.

These vehicles may monitor crankshaft acceleration closely for misfire detection. A substantially lighter flywheel can change crankshaft-speed behavior enough to produce false misfire detection or drivability problems.

Before installing the kit on one of these models:

1. Confirm the exact Fidanza flywheel part number.
2. Ask the seller which Hondata calibration is required.
3. Verify support for the vehicle’s ECU.
4. Consult an experienced Honda tuner.
5. Complete the required calibration before aggressive driving.

Do not disable emissions or safety-related diagnostics simply to make a mismatched part work. Consult Hondata’s official product information for compatible tuning hardware and software.

Who should buy this kit?

This package makes sense for:

• Naturally aspirated K20 and K24 street builds
• Stock or mildly modified RSX and Civic Si models
• Drivers seeking faster rev response
• Autocross or occasional track vehicles
• K24 applications being converted to a K20/Type-S-style clutch
• Owners who want OEM-like clutch engagement

It may not be ideal for:

• High-torque forced-induction builds
• Drivers wanting factory flywheel refinement
• Vehicles without confirmed manual-transmission fitment
• Later K24 vehicles without the required ECU solution
• Owners unwilling to tolerate additional drivetrain noise

Installation considerations

While the transmission is removed, inspect:

• Rear main engine seal
• Transmission input-shaft seal
• Clutch fork and pivot
• Master and slave cylinders
• Hydraulic clutch hose
• Axle seals
• Engine and transmission mounts
• Flywheel and pressure-plate bolts

Before installation:

• Confirm every supplied part number
• Compare flywheel offset and ring-gear position
• Verify the crankshaft bolt pattern
• Test the disc on the transmission input shaft
• Check clutch-disc orientation
• Clean both friction surfaces
• Follow the specified tightening sequence
• Use the correct flywheel and pressure-plate torque
• Perform any required ECU calibration

Use manufacturer-approved hardware. Aluminum flywheels and cordless impacts are not a romantic pairing.

Break-in procedure

Follow the instructions supplied by EXEDY and Fidanza. An organic clutch normally requires approximately 400–500 miles of moderate street driving.

During break-in:

• Avoid hard launches
• Avoid full-throttle acceleration
• Stay out of boost
• Do not race or perform dyno pulls
• Avoid excessive clutch slipping
• Use repeated normal engagement cycles

Steady freeway mileage produces very few clutch engagements and should not represent the entire break-in period.

Final verdict

This EXEDY and Fidanza package offers a useful balance of street-friendly clutch engagement and lightweight-flywheel response. It should work well for compatible naturally aspirated or mildly modified K-series vehicles when the correct conversion components are supplied.

Fitment is more complicated than the broad title suggests. The standard EXEDY clutch does not independently fit every listed K20 and K24 model—the Fidanza conversion flywheel is what connects those applications. Confirm its part number, resolve the 213/215 mm disc discrepancy and understand the Hondata requirement before installation.
