    ACT StreetLite Flywheel ( Part Number: 600175)
    Great upgrade from stock flywheel 2 months ago
    Victor
    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  10 months ago
    SS
    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

    Nice Upgrade for Street 10 months ago
    jwernerny
    When replacing the clutch at 150k miles on my '02 WRX, I was advised I should also do the flywheel. I decided to go with this lightened flywheel and a slightly heavier clutch. The original flywheel (AFAIK) comes it at 22 lbs. This comes in at 14 lbs (roughly 25% lighter). Yes, that does mean that the engine revs faster, and the rolling acceleration seems a bit better (and don't think it is just the $$ factor, but I didn't measure first). BUT, there is a small drawback -- the 25% loss in mass also means a 25% loss of rotational momentum (at a fixed) rpm. That means you end up having to rev the engine a bit higher when releasing the clutch when starting from a stop or especially when on a hill. If you add in a new, stronger, performance clutch (which are often grabby at first), this creates an interesting experience during clutch break-in. You either stall it, smoke it, or spin the tires. Once the clutch breaks in, it is not a problem, but until then, it is interesting. (My break in was about 1 month of driving the car twice a day on the expressway.) So far I have not had any problems with throwing CEL codes because of the lightened flywheel. BTW, both the flywheel and clutch were installed by my mechanic, so ease of install is meaningless to me.

    QUESTIONS & ANSWERS

    • Q: 2003 Subaru WRX Wagon  AdamSubaru1236 months 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  ap2bruce12 months 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.
