    Built for the Subaru WRX Manual Transmission

    Most aftermarket drivetrain parts target the 6-speed, since a clutch, flywheel, and short shifter only apply if there's a pedal on the left. ACT, Exedy, and South Bend Clutch all build stage-specific clutch kits that hold up past stock power levels without turning the pedal into a leg workout.

    Pairing a new clutch with a lightweight flywheel from the same brand sharpens throttle response and cuts the time between shifts. Most builds start with a stage 1 or stage 2 clutch, since anything beyond that trades daily drivability for outright holding power.

    Tighten Up the Shifter Feel

    A Perrin or COBB shifter stop tightens up a Subaru WRX transmission's throw, and Kartboy shifter bushings remove the sloppy feel factory rubber leaves behind.

    What Your CVT-Equipped WRX Still Needs

    CVT owners aren't left out, even though the parts list looks shorter.

    Torque Solution and Perrin pitch stop mounts cut drivetrain movement under hard acceleration just as much on automatic cars as manual ones. Engine and pitch mounts don't care which gearbox sits behind them, since the movement they control happens before power ever reaches the transmission.

    Parts That Work Across Both Transmissions

    A Cusco reinforced differential carrier strengthens the housing that both transmission types rely on for power delivery to the wheels. Whiteline bushings throughout the drivetrain reduce flex regardless of which Subaru WRX automatic or manual transmission is under the car.

    Every listing on JDMuscle's Subaru WRX transmission page includes verified fitment details, so a clutch, mount, or bushing matches your specific gearbox before you order.

    FAQs

    Can I put a manual transmission clutch on my CVT WRX?

    No. A CVT doesn't use a clutch disc or flywheel the way a manual does, so clutch and flywheel upgrades only apply to 6-speed cars.

    Do transmission mounts help CVT cars as much as manual cars?

    Yes. Mount and bushing upgrades address engine and drivetrain movement that happens regardless of transmission type, so both manual and CVT owners see the benefit.

    What does a pitch stop mount actually do for a Subaru WRX transmission?

    It limits how far the engine rocks under hard acceleration or braking, which keeps power delivery consistent and reduces wear on other mounts over time.
