    Great clutch 12 months ago
    SS
    After break in, this clutch is right there. Does take a little getting used to from the stock clutch, but well worth it when you do. Slip it a little more on easy take off. Rev the engine and let it fly and it hooks up hard. Nice. Pricewise the stock clutch is about the same price from Subaru but tons better.

    Good Upgrade - Don't Judge Until AFTER Break-in 1 year ago
    jwernerny
    This clutch replaced a worn out, 150k mile (original!) clutch on my '02 WRX. It was put on with an ACT Street Light Flywheel. When I picked the car up from the mechanic, he warned me that the clutch grabbed very aggressively. I stalled it twice as I was pulling it out from his shop. That was my first impression of the clutch, but I also knew that I needed to wait until the clutch had a chance to break in. During that time I had to learn how to compensate for the lightened flywheel and learn how the clutch liked to engage. Now, a month and a half later, the clutch is fully broken in and I am enjoying how it behaves. It has gone from being an on/off switch to progressive engagement that even my wife (who normally drives automatic) and drive without problems.

    Good but wore fast. 2 years ago

    I've had this clutch in my WRX for about 30,000 miles now and at first when I was only making 250 wtq it would grab really well but once I put in my new turbo and started making 310 who and 280 wtq it has started to slip when I shift at the 6800-7000 range. But only after I shift into the next gear, it never slips before I shift. I didnt think I would have any problem with this torque number but I guess I was wrong.

    act heavy duty clutch  2 years ago
    SavageWRX
    I installed this clutch kit with a light weight flywheel . My car is making around 350 whp, 340 wtq. The clutch doesn't slip at this point, 5000 miles. Shifts smooth, a little chatter on slow engagement at low rpm, pretty "grabby" clutch, pedal is a little stiffer but not by much. Over all , I am happy with it.

    QUESTIONS & ANSWERS

    • Q: Clutch   Jeffery5 months ago

      Will this clutch work well with a 350whp forester?
      • 0 of 0 people found the following answer helpful

        A:  It will depend on how much wheel torque you're making. Assuming that's around the 350wtq mark as well, this would be a good choice, but you'd be right around what this clutch is rated for. The Xtreme Duty might be a better option if you plan on adding power in the near future or if you want some headroom.

    • Q: Flywheel   nickbell2818938259 months ago

      Can this be bolted up to a OEM flywheel or do I need a aftermarket one?
    • Q: Fitment on tranny swap  Nelson Asay1 year ago

      Hi! So I am looking into swapping my 5 speed with a 6 speed. But I wanted to know will this clutah work and fit with a 6 speed transmission? Thanks!
      • 0 of 0 people found the following answer helpful

        A:  No, this clutch is for 5-speed transmissions found in Subarus like the 2002-2005 WRX. You are going to want to match the clutch with the transmission you are swapping with.

    • Q: Autox  Gearhead264816503 years ago

      Hi, I currently have an 02 wrx that I Autox in SMS. The car makes around 350 to the wheels and I am in the market for a clutch that will withstand 200+ Autox runs. I have 2 seasons on the one I have now (not including the prior owner) which is a stage 2 (or as I was told)
      • 0 of 0 people found the following answer helpful

        A:  This clutch is rated at 430ft/lbs at the crank so 350ft/lbs at the wheels might be just about where the torque capacity sits depending on drivetrain loss. Mileage or runtime is difficult to determine and depends on how the vehicle is used.

    • Q: Clutch question   shawsworld273 years ago

      I have a 2003 wrx built ej2.5 motor and RA transmission gears I run 383 awhp and use this car as a daily driver, I have used an act 6 puck sprung clutch, act basic street disc before my build and Exedy street disc twice, I do drag race sometimes what would be the best option for me for smoothness, grip, and longevity
      • 0 of 0 people found the following answer helpful

        A:  Clutch kits with an organic disc, like this one, are going to be the smoothest, last the longest, and are recommended for daily driven vehicles. This clutch kit is rated for 430 ft/lbs at the flywheel (approximately 340 wtq), and may not hold the power that you are making.
