    Act hdss clutch/streetlite flywheel 7 months ago
    GCTuned
    While the car at the moment is in a break in map(reduced throttle response, and lowered boost), the engagement had moved slightly up of the pedal. However, when it does engage, it does in a aggressive manner compared to stock clutch. I only have about 100 miles on the clutch, but i can already tell this clutch is a beast with more of a on/off personality. Even with the reduced throttle mapping on downshifts i only have to tap the throttle to get it to the right rpm. I have even over shot the downshift rpms by accident...cant imagine after its fully tuned. Slight chatter on in gear decceleration, but gives it a nice “race car” sound to it combined with the sti transmission/motor/pitchstop mounts. Will report after break in period and once fully tuned. So far, its a beast of a clutch with slightly higher engagement. I like!

    Great while it lasted  2 years ago
    chrismather9192838
    I don't have much to say about this. Very happy with how it came, packaged great everything was there and everything was correct. Install was easy and everything worked right. It is a good clutch for the money (I guess). It worked great while it lasted. My car made 326hp/342tq on the dyno (from a reputable tuner on the east coast) with a new intercooler. Fast forward 8000 miles and my clutch is already slipping. Needless to say I was unimpressed.

    Torques 3 years ago
    battlegorge
    It couldn't handle the horse torques but that is wheel torque so I did go over its rating after about 2 weeks of driving with that power it now slips under boost I guess I expected it though

    i have a 2014 WRX with a GTX3071r on e85 putting down about 450ftlb of torque to the wheels, ACT rates this clutch will hold up too 400ftlb at the crank! not the wheels! clutch only lasted at this power/torque level for two months, it was holding up well on my stock turbo e85 set up, but did not with the 30r. I would recommend this clutch for anyone staying around 350ftlb torque at the wheels anything more go for something different.

    The worst investment i have ever made 3 years ago
    subliminalforce
    The pressure plate is too stiff for the shift fork, this will be my second time replacing this setup because it has severely bent and almost snapped the clutch fork to the point where I can't turn the car on. I have called ACT for compatibility issues and I was never given an answer, I think RSD should take this product off the shelve until proven compatibility and reliability. However, it fits and you can go about 6 months of daily driving! and the rest is history. You can start to feel the pedal get loose and then whining from the flywheel. And not just the regular flywheel sound, something wrong is happening. Im hoping to replace something that will have a warranty through the shop because this is ridiculous, and if it's being adverstised as a "superior" clutch system make the buyers aware of all the malfunctions prior to purchase.

    • Q: Will this work on a oem flywheel?  WRB WRX2 years ago

      Trying to find a clutch that will hold 370wtq without changing to a light weight flywheel. Don't want extra noise or chatter.... would this work on the oem flywheel?

        A:  This is designed to fit the OEM flywheel, however Subaru does not recommend that you resurface their flywheels.

    • Q: clutch break in  espino003362033 years ago

      hi there, i just installed act hdss for 2014 wrx, im wondering how to break in this new clutch? thanks in advance.
      • 0 of 0 people found the following answer helpful

        A:  Break in process for a new clutch will typically be 300-400 miles, with plenty of stop/go and keeping the RPMs under 3000k and NO LAUNCHES. Essentially, you want to focus on engaging/disengaging the clutch, during the 300-400 miles. Please note that freeway miles to do not count, and you will want it to be 300-400 miles of stopping/going and engaging/disengaging the clutch.

    • Q: Reliability   Santi3 years ago

      I am running a Cobb 20g on a 2008 WRX with fmic, catless TBE, and other goodies. I have an OEM Exedy clutch (lol I know) and it has started causing issues since I'm in the 380-420hp range. So, I was wondering if I could use this or should I go bigger? Because I do plan on doing engine work and shooting for a solid sub-500 goal. Probably around 480 or so.

        A:  Santi, If your car is a daily driver I would suggest running this kit. It will have a slightly stiffer pedal than stock with a nice drive-able solid engagement. Keep in mind ACT clutches are rated by torque at the crank and this kit will hold up to 420 ft/lbs of torque at the crank. For the SB5 kits, if you were to "go bigger" the difference would be to change from a street disc to a puck style disc which will hold more torque. The trade off for switching to a puck style disc is less modulation in the clutch pedal, etc. The clutch will engage like a light switch on/off and the longevity of the part will decrease with a puck style disc.
