Applications that should be removed
For a North American product page, do not list:
- 3.0L EZ30 Legacy models
- 3.0L EZ30 Outback models
- Automatic-transmission vehicles
- Lineartronic CVT models
- WRX or WRX STI models
- Turbocharged Forester XT, Legacy GT, Outback XT or Baja Turbo models
North American EZ30-powered Legacy and Outback models used automatic transmissions. No clutch pedal means no clutch kit—an engineering detail that remains surprisingly relevant.
Some international-market 3.0R models were offered with manual transmissions, but those applications require separate market-specific confirmation.
Engine-code corrections
The supplied listing identifies every 1998–2013 Forester as an EJ25 application. That is inaccurate.
- Earlier naturally aspirated Foresters used EJ25-family engines.
- Later third-generation Foresters transitioned to the FB25.
- Crosstrek and later Impreza 2.0L models generally use the FB20.
- Turbocharged EJ255 applications require a different performance clutch listing.
The page should identify the exact engine and transmission rather than grouping multiple engine families under a generic “2.5L” label.

OEM-style driving characteristics
This kit is designed to maintain normal street behavior rather than provide the aggressive engagement of a ceramic racing clutch.
Expected characteristics include:
- Progressive clutch engagement
- Manageable pedal effort
- Smooth takeoffs
- Low-speed drivability
- Reduced chatter compared with puck-style discs
- Suitable performance for stock naturally aspirated engines
No horsepower or torque rating is provided. This kit should not automatically be used on turbocharged or substantially modified engines.
For help comparing clutch designs, read the Pro Street performance clutch guide.
Impreza fitment needs extra attention
The 1998–2023 Impreza range spans several generations, engine families and manual transmissions. Not every Impreza built during those years uses the same clutch.
Before ordering, confirm:
- Model year
- Engine code
- Transmission code
- Naturally aspirated configuration
- Clutch-disc diameter
- Input-shaft spline count
- Flywheel dimensions
- Complete ClutchMaxPRO part number
Later Impreza models were commonly sold with a CVT, although selected trims retained a manual transmission through 2023. The existence of a manual option does not prove this exact clutch fits every year.
Crosstrek and XV naming
“XV,” “XV Crosstrek” and “Crosstrek” can describe related vehicles depending on model year and market.
For North American listings, the useful application is generally:
- 2013–2015 Subaru XV Crosstrek 2.0L manual
- 2016–2017 Subaru Crosstrek 2.0L manual
Avoid listing XV and XV Crosstrek as separate vehicles when they refer to the same regional model.
Signs of clutch failure
A worn Subaru clutch may cause:
- Engine speed increasing without matching acceleration
- Slipping during hill climbs
- Burning friction-material odor
- High engagement point
- Chatter during takeoff
- Difficulty changing gears
- Release-bearing noise
- Reduced acceleration under load
Subaru drivetrains can also transmit noise from worn engine mounts, transmission mounts, driveshaft components or wheel bearings. Diagnose the fault before assuming the clutch is responsible.
Browse the Subaru technical archive or visit the complete My Pro Street DIY library for additional diagnostic information.
Flywheel inspection
Because this clutch kit does not include a flywheel, the existing unit must be inspected carefully.
Check for:
- Heat spots
- Cracks
- Scoring
- Excessive wear
- Incorrect step height
- Surface runout
- Damaged ring-gear teeth
Subaru flywheel step height is critical to pressure-plate clamping and release operation. Resurfacing must preserve the correct relationship between the friction surface and pressure-plate mounting surface.
Simply machining everything flat can produce incorrect clutch operation. Flat is lovely for countertops; stepped Subaru flywheels are less impressed.
Installation recommendations
While the transmission is removed, inspect:
- Rear main engine seal
- Separator plate
- Transmission input-shaft seal
- Clutch fork and pivot ball
- Release-bearing guide surface
- Clutch master and slave cylinders
- Engine and transmission mounts
- Axle seals
- Driveshaft joints
Before installation:
- Verify the engine and transmission codes.
- Compare the new and removed clutch discs.
- Confirm the 24-spline hub.
- Verify disc orientation.
- Check flywheel step height and runout.
- Clean all friction surfaces.
- Tighten the pressure plate gradually.
- Follow Subaru’s torque sequence.
- Bleed the hydraulic system properly.
Break-in procedure
Follow the instructions supplied with the exact ClutchMaxPRO kit. A new full-face clutch normally requires several hundred miles of moderate stop-and-go operation.
During break-in:
- Avoid hard launches
- Avoid full-throttle acceleration
- Do not tow heavy loads
- Minimize excessive slipping
- Use smooth engagement cycles
- Avoid holding the vehicle on hills with the clutch
Highway mileage provides relatively few clutch cycles and should not constitute the entire break-in period.
Final verdict
The ClutchMaxPRO OEM kit may be a practical replacement for compatible naturally aspirated Subaru and Saab models with manual transmissions. Its full-face clutch disc and OE-style pressure plate should provide suitable manners for daily driving.
The advertised fitment needs substantial correction. Remove North American 3.0L Legacy and Outback applications, distinguish EJ25 from FB25 Foresters, exclude turbocharged and CVT models, and verify the exact transmission for later Impreza and Crosstrek applications.
