One of the Best Full-Face Clutch Kits for 400+ WHP
D3LTAwrx 10 days ago
I have used ACT for a while and have had mixed results with the 5-speed kits on my WRX. When I wen to do a STI transmission swap I was still a little skeptical but chose this clutch anyways. Well the clutch has been awesome so far! I have put about 500 miles on it since the install and it hasn't given me any issues yet. I did the install myself and made sure to take my time and torque it all down correctly and it really paid off. I had almost 0 chatter during break in and now at 500 miles it is completely chatter-free. It drives as easy as any stock clutch with only a stiffer pedal IMHO. I am using this with the stock STI flywheel and it is great!

Excellent quality and fantastic performance!!
jeepman 3 months ago
The packaging to preserve quality was better than any I have ever seen before. Installs as any other clutch would. Pedal push is heavier than the stock clutch but not nearly as extreme as others have made it sound. I was actually concerned about the weight of the pedal and then pleasantly surprised.. I had some shuddering on engagement for the first 100 break in miles or so, but then it went away and engagements are smooth. I run a 485hp 460tq STI and it holds the power just fine.

Act clutch
Jefournet200949668 6 months ago
Combined with act streetlite flywheel. Grabs better than stock. Engages slightly earlier but I'm over it. Easy to drive on street which is what I do 99% of the time. Overall great upgrade. Can't wait to burn some of it off at the track!

Clamps down well!
RoMo12 12 months ago
Dropped in a new motor into my 2015 STI and used this clutch to match to the 450wtq. It does the job well done. It grabs the next gear with no fuss during straight line acceleration. It drives similarly to the OEM clutch during daily driving. Initially, this clutch felt significantly heavier over the OEM. It chatters during break-in. Now, with over 5K with this clutch, chatter is virtually non-existent; although, only during slow "going over the speed bump" type of speed. I demanded this to clamp down during a 4500rpm launch, and it obliged to the task with flying colors. Video of the launch below (skip to :40). Happy with this ACT clutch!

I installed this with the oem flywheel and I'm getting some shaking of the car on first gear like when the car wants turn off I hope it gets better as it breaks in more. I love this clutch expect for that making my whole car shake violently on 1st gear.

Great clutch!
Harry Williams 1 year ago
I was torn between a few clutches for my new STI, but after driving my buddy's southbend stage 2 I knew i wanted the strong snap of the ACT extreme pp. I had 2 act's and 1 CM on my old WRX and missed the feeling. So far it feels great. I only have 150 miles in it, but it holds power fine. Easy if instillation, well it's a clutch job. But everything installed well and quality is great. I highly recommend this if you prefer a heavier feeling clutch. I daily drive this in NJ traffic and it's fine.

  • Q: Performance  Sir Barton 3 years ago

    Answer

    when spring hits I'll have around 475ftlbs of torque at wheels, I don't launch my car often but how well does this clutch handle launching because sometimes I'd like to see how it runs at drag strip, thank you


    • A: Clutch kits like this with organic discs will hold up to occasional launching, but segmented or puck style discs are recommended if you plan on launching the car. ACT rates their clutches for power at the flywheel, and if you will have 475 wtq, then a clutch kit with a higher power rating is recommended.
