  • Q: Loud TOB  ckbeep10 months ago

    Have used 2 of these kits on 06 wrx. Act clutch, act LW flywheel. Both have had noisy throw out bearing that does not go away unless apply slight pressure to clutch pedal. Happens with less than 100 miles put on clutches. I have researched and this is a common problem, have seen few remedies but seems like fixing the noise not the problem temporarily. Any advice on how to fix. Have read adjusting the preload on clutch pedal. But heard differing views. Says can wear out bearing. Also, read about greasing clutch fork and slave cylinder where pin meets.

  • Q: Will this work on a oem flywheel?  WRB WRX3 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?
    • 0 of 0 people found the following answer helpful

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

  • Q: clutch break in  espino003362034 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   Santi4 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.

  • Q: I broke my fly disk  andrewmjsinko5 years ago

    I have an 11 sti limited and on a launch last night, Im pretty sure I broke the disk. The burnt clutch smell is really bad and when I'm driving normally, the rpms will shoot from 3 to 6,7 out of no where and the smell returns. My question is, did my fly disk go on me? And can I order this part to replace it. I haven't done any kind of mods, so will this work, or should I go with an oem?
    • 1 of 1 people found the following answer helpful

      A:  It sounds like you toasted your clutch and will need a replacement, This is a nice upgrade and will be able to handle more power when you do any sort of modification.

  • Q: DD  Cbarks135 years ago

    Is this clutch good for a daily driver? Looking for a new clutch and a new flywheel.. My 2012 wrx is only stage 1 with a v3 accessport.. never had a protune on it.
    • 0 of 0 people found the following answer helpful

      A:  This will be fine. The pedal will be stiffer than factory, but will still be okay for daily driving.

      A:  What are you plans for power upgrades in the future? I wouldn't do this on a mildly upgraded daily driver, I think there are better ones out there. I had two fingers break on the presure plate on my daily driver, and I hated the decel chatter.

  • Q: 07 spec.B fitment  Charlie Tango5 years ago

    Will this fit my 2007 spec.B? If I purchase a 06-07 FW? I know the other clutch y'all sell will with an STi FW. Also, if I wanted to match it with a LWFW, would I need to purchase an 06-07, or would a FW specific to my car fit this clutch?
  • Q: 2013 WRX  MazdaRotaryRX7096765 years ago

    So without boring u with the list of mods on my car, I will just say that I put down 300awhp and 360awtq on a dyno dynamics, which I'm told read pretty low. My car is a DD and I'd like to have similar driveability as the stock. My question is will this clutch be enough or should I think of getting something stronger? Stock clutch only lasted about 14,000 miles, 6000 miles of which it had my current modifications before slipping.
    • 0 of 0 people found the following answer helpful

      A:  This would be a pretty solid clutch in terms of drive ability and it will definitely be able to handle the power that you're putting to the wheels without issues.

      A:  Rating is at the Crank that ACT provides. On a AWD car you have about 25+-5% Drivetrain loss

  • Q: how long  sramnarain6880446 years ago

    has anyone had this clutch for a while?
    • 0 of 0 people found the following answer helpful

      A:  With Clutches being a wear item, different power levels, and different driving styles it is always hard to say how long a clutch with last. There are a lot of factor to play on the life of the clutch and what you will using the car for. Drag racing and launching can always be more abusive than street driving, but if your car is making more torque that want the clutch is rated for or if you are stock torque will also play key roles in your clutches life. I recommend talking to a representative or even a manufacture to find the best clutch for your driving style and needs.

  • Q: Throwout bearing squeal  Minimetj13494377 years ago

    I installed this clutch ~200 miles ago. I've babied it so far but my throwout bearing is making a loud squealing noise but if I press the clutch in it goes away. It's gradually getting louder and I can hear it while driving now. The shop that installed it says it's normal but I'm a little worried cause others say it's not.
    • 0 of 0 people found the following answer helpful

      A:  The Throwout bearing shouldn't be making any noises. I would have it removed and looked at to be safe.

  • Q: Torque Capacity  ironstuner22709747 years ago

    Hey guys- how does this clutch torque capacity of 420ft/lbs translate to WTQ, does it mean it has the capability to handle up to 420WTQ? Also, I am currently making 349WTQ on my stock VF52 turbo and I am about to install my Dom 1.5xt-r. I expect to make a significant amount more of torque, do you think this clutch is adequate or should I upgrade to the ACT Heavy Duty 6-Puck? Thanks.
    • 1 of 1 people found the following answer helpful

      A:  ACT power ratings are measured at the flywheel and you will need to account for drivetrain loss when comparing to torque measured at the wheels. Your torque will exceed ACT's rating, but this clutch may still hold the extra power because the clutches are underrated.

  • Q: Stage 2  hoda822078 years ago

    I am about to upgrade my 2011 wrx to stage 2, and am looking to upgrade my clutch for when I'm launching and putting out some speed. Would this be the way to go and should i get the Exedy lightweight flywheel as well?
    • 0 of 0 people found the following answer helpful

      A:  Its never a bad idea to upgrade the flywheel at the same time as doing a clutch. The lighter flywheel will help reduce rotational mass and help engine response. As for the clutch, this unit should have no problems holding your power levels at stage2

  • Q: will it bolt to a stock flywheel  2010 subaru8 years ago

    Will this clutch have a direct bolt on to a stock flywheel?
    • 0 of 0 people found the following answer helpful

      A:  For a WRX yes this will be a direct bolt on and will work with the stock flywheel. However for a Legacy GT it does require a flywheel change to the WRX style, to remove the stock Legacy GT duel mass unit.
