Favorite clutch?
 

Hey guys I am looking for a clutch to hold over 265lb ft, but want something close to "stock feeling," minimal noises, streetable, ect.

Seems like most guys prefer ACT 6 puck from my research, other swear by Clutch Masters (Fx 300), or Exedy Stage 2, and even Southbend Stage 3 endurance was recommended.

Here was a thread a few years back.

What are you all running and what are the preferences? Please post what you think with a poll and details, thanks!

OS Giken GTS1CD. Feels very close to stock.

I have a OS Giken TR2C, its has a pretty short engagement range(really sensitive) vs stock. Its overkill for the car though, no 1st gear lockout however.

SB Stage 3 endurance with a Stage 2 flywheel. I love my setup. Follow the break in to the T. It's a long time but it is worth it. No chatter. No jerkiness. No trouble in stop and go or on hills. I am running 350HP (278 lb ft tq) now and it is a champ. I am a fan for life.

ACT HD-SS.

Nice smooth engagement, slightly heavier pedal feel.

I've searched, I couldn't find the answer, will the FA20DIT clutch work in our cars?

No, they use the same clutch as the previous WRX if I remember correctly. They will not fit ours. The discs may be similar or shared with certain other models especially for aftermarkets, but not the full clutch assemblies.

Action Stage 2 is a great choice and price. I have a south bend now and it's so so. Also when I last checked south bend had discontinued the clutchs for our cars

My south bend will come out this winter for a Action Stage 2

Were there not issues with the Excedy clutches in the past? Or have those issues been resolved now? The last time I read up on Excedy was a couple months ago.

I have an exedy stage two with 12lb fly wheel. I like it a lot.

This was for my celica. It failed in under 20k and I was about 100 torque under it's limit.

My newer ACT-TC2-HDG6 may be over kill but it feels awesome and I can only burn my clutch if I am trying.

Yeah people were having problems getting locked out of 1st, lots of chatter, and problems in general. Apparently they came out with a revised version that fixed these things a few months ago, (Exedy stage 2, 3 puck #15955) but it uses the stock flywheel, and a lightweight Exedy one is expensive so I am kinda iffy.
On another note I drove a twin with 305whp and an ACT 6 puck, pretty nice but basically an on off switch, a little chatter etc. Pedal feel was slightly more than stock which I liked, but the catch point was tricky. Felt similar to a 400hp evo with some aftermarket clutch I drove last year. Seems like people get good and bad ones but I know they are coming out with a revised Streetlite at the end of September that should make it easier to drive.
Anyone else? what about flywheels?

Have competition clutch stage 4 with sprung 6 puck and lightweight flywheel. Clutch pedal is stiffer than stock. Catch point is a little tricky and there is a little chatter. Overall i like it.

ACT SB7-XTSS after 500 miles disengages and engages like factory but with a stiff pedal. No chatter

@wootwoot Hows that lightweight FW treating you while being boosted? Ive got one laying around and would love to throw it in but am told it turns the idle to shit.

Your tuner can take care of that.

I just bought a ACT HD-SS. Thanks for the recommendation @Mike CSG. Pushing 12psi on e85.

My south bend stage 1 disc is not very pleasurable for street driving. Clutch feel is like stock, not any stiffer. Engagement point is same as stock. But, I get bad shudder/vibration on release if I have to slip it any in stop/go traffic. This is the biggest kicker to this clutch setup, since I purchased it for DD duty, and specifically chose the "Daily" variant for OEM like engagement.

Damn, Why didn't I know you stock these clutches @CSG Mike? I would have bought from you and saved a few bucks too.

Whats the difference between ACT SB7 and SB8? All the specs look the same, ones like 2 lbs lighter. Please help!

That's the only difference, the flywheel.

We're using the 11.8lb flywheel based kit and the clutch is quite nice.

I'm using the Streetlite flywheel with my ACT clutch, love it.

SB7 XTSS

The ACT w/ the HD PP held up to 452whp/350wtq on the dyno today. This clutch should be good for the vast majority of us.

I'm considering the Exedy Stage 1 for my supercharged frs, thoughts?

WHOOOOOOA. I just slipped the hell out of my new ACT HDSS. I was just farting around on industrial roads today. Pulled hard through second gear. Then when I hit third gear, the tach just spiked to 7400rpm as I hit full boost almost immediately. :( Tons of stinky smoke and not from the tires at all.

I need to dyno my car to see what kind of numbers I am actually making. Stock block, 6758 EFR, e85, 12psi. I installed this HDSS about 10 days ago and been babying it. I feel like I did the break in period correct and am well beyond the 500 mile mark. What gives? I thought this clutch was rated at 270wtq, I shouldn't be anywhere close to that.

Thoughts?

To be honest my clutch wasn't right until after 1000 miles. The first 100 was fun. But I'm using the XTSS rated for much more but still disc not puck.

@GsxrMe Hows the pedal feel and engagement on that XTSS? The pedal feel on my HDSS is maybe 30% stiffer than stock and the engagement is predicable albeit I need a few hundred more RPM to get a smooth takeoff.

were did u buy your action clutch? i dont see many distributors

500 miles is a pretty conservative clutch break-in period. Last clutch I installed took like 2000 miles to break in before it stopped slipping.

As a side note, someone should guinea pig the ORC 599D twin plate. :thumbsup:

The ACT 6 puck doesn't like nearly 400wtq. Kinda slipped a bit, lol.

Like a Mustang GT feel. Only reason I say that is my bud has a 2015 Mustang GT

I have a gtx2867r and on 10.5 psi and made 322/273 to the wheels, you could easily beat that on 12psi on e85. You have it dyno tuned? Is it still slipping or did you just heat up the clutch really bad?

@Readytoxplod Wow, I didnt think I would be anywhere near 270. I have a dyno scheduled next week to verify. It isnt slipping at all and I have tried to recreate it to no avail. Maybe it wasnt broken in entirely. I bet I burned 25% of the friction material off haha.

Mine didn't start to slip til almost 400wtq. It's a beefy clutch, and it's still holding fine on the street once I backed it off down to 350-360wtq. Granted my clutch is still fresh, 300 miles on it. lol

300 miles is the break-in recommended by ACT, strictly city miles no highway. Honestly just driving to where you heat it up, then letting it cool and repeating for 200-400 miles is the best way to break in a clutch. You should be fine, like someone else said they lowball the tq ratings and a few clutch slips, hard launches or fucked up shifts shouldn't mess it up as long as you let it cool down completely so you don't glaze your disk.

Did you ever get that dyno? With your turbo setup @12psi on E85 and if your tuner pushed the timing a good bit you could definitely be over 270tq. Remember the clutch sees crank torque, before the transmission/drivetrain losses.

yeah I have a feeling you may be pushing the limits of that clutch with your setup on e85! Change clutches, I'll buy yours off you (: lol

Dont tempt me. Im eye balling a ACT 6 puck now haha

Better decide soon, I'm going to place an order for the HDSS soon... :p

I have the XTSS it's rated for 347 ft lbs. At any point I need more I'll go twin disc and never go puck. My old puck on/off feeling sucks and the clutches life span was extremely short. The XT model is the same as the HD but a heavier pressure plate.
