    ACT StreetLite Flywheel ( Part Number: 600175)
    Good if you have an AP or dont mind possible occasional CEL 3 months ago
    5out of 5stars

    Great flywheel, If you are decent at feathering the clutch and don't drive exclusively on hills, I would recommend this flywheel for daily driving. The amount of speed you gain in revving and downshifting is worth it alone, not to mention the nice race car level gear whine you get. And its cheaper than OEM flywheel as well. If you get misfires after installing this don't worry, its your crank angle sensor.

    Very nice upgrade! 11 months ago
    5out of 5stars

    This was for my JDM GC8 WRX that needed a new clutch, so might as well get a new flywheel too and am very happy with this one. This was pared with the Exedy OEM clutch kit and was installed professionally. Drivability is about the same, you just need to give it a bit more gas when starting but doesn't make my car harder to drive. Rev-matching is a lot easier and quicker now. The only con I've experienced is engine braking is reduced quite a lot.

    Great upgrade from stock flywheel 2 years ago
    5out of 5stars

    Paired this with the Exedy OEM clutch on my 2005 WRX. Revs and gear shifts are faster. Takes some getting used to but once you get the feel of it, it's great. The "chatter" is almost non existent, especially if you have a cat back. Over all a great improvement over stock.

    There's always horror stories about gear rattle and other obnoxious sounds that occur when installing a lightweight flywheel, but this one is quiet as if it were OEM. Paired with an EXEDY OEM clutch, the drivability is much better than stock. If for whatever reason you need to pull your tranny or engine, this is a great upgrade to do while you have it out.

    A must when replacing clutch  3 years ago
    5out of 5stars

    Appears to be half the weight of the OEM Easy install. Bolts up easily. Combined with the ACT clutch assembly it was and easy install. Engine revs a bit easier at idle and between shifts. Very nice. Much better tha OEM

    • Q: Light weight pulley and flywheel  pilcherm7 months ago

      Can I install a Light weight flywheel and a light weight crank pulley on the same engine?
    • Q: CEL Question  04 & 10 wrx owner2 years ago

      On other websites that sell this flywheel it is mentioned that the quicker recognized may cause a check engine light to come on b cause the computer doesn’t expect it to rev up as fast as it does. Do you know of this issue being the case?
    • Q: Service   Scap2 years ago

      Do you know if this flywheel can be resurfaced?
    • Q: 2003 Subaru WRX Wagon  AdamSubaru1232 years ago

      How does this affect driveabilty? Pros/Cons? Do you guys have any OEM replacement flywheels?
      • 0 of 0 people found the following answer helpful

        A:  Lightweight flywheels typically make the vehicle a bit easier to stall, but also have the benefit of reducing rotating mass on the motor, which typically results in more power to the wheels and quicker revving for up and downshifts. We do offer OEM flywheels for certain vehicles, but we don't have one confirmed for the 03 WRXs at this time.

    • Q: Compatibility  ap2bruce3 years ago

      How will this flywheel work paired with a stage 3 competition clutch? I'm making 366 wtrq.
      • 1 of 1 people found the following answer helpful

        A:  ACT nor Competition clutch confirm this flywheel to work with any other clutch than ACT's. I would recommend purchasing a Competition Clutch flywheel.
