ACT Street Disc is a piece of shit.

I have a team of Lawyers backing me already. My father is an admin for a law firm in VA Beach. But most likely it will be a "You pay if you win kinda deal"

 

[RoasT BeeF]

Ok well I will reply to your thread I guess its worth a shot. Afterall if it hadnt been for you this would be going nowhere.

Still pisses me off that whoever I talked to didnt even tell me any of this tho.

If you like how the ACT clutch drives, then I would suggest an ACT 2600 pressure plate with an Exedy disc. I personally have an Exedy setup that is rated at 1940 lbs of clamping force and it has taken a few 1.7 60' launches and over 2 years of aggressive street driving and has never slipped. My next clutch will be the exedy unit with the six puck cerametallic disc. Also for you 92-99 DSMers, if you have the cash, Exedy offers a twin disc setup for the 7 bolts. For those of you with the clutch problems, I'm sorry to hear about it. :thumbdown

 

[badboyr66]

hmm Exedy huh? I am kinda curious about that. Anyone else use these? I need somethin for low 12s high 11s. I was going to go ACT, but now I am kinda spooked, any sugjestions?

All DSMs have the same bolt pattern for the clutch so it would work. however, If it replaces the flywheel then it won't work. 90-92 have a 6-bolt flywheel and 92-99 have 7-bolt, sucks for us!

You could go 2600 Pressure plate, with and exedy disc, ACT2600 with puck disc or full Exedy.

The problem is the ACT Street Disc.

I have a ACT2600 w/ a street disc... just recently i've noticed a chatter/knocking sound.. a little metallic sounding in there.. it only happens @ low rpm in reverse.. like when i barley let off the clutch - i think roastbeef had that same problem too. i had mine installed in november.. no more than 6000 or so miles on the car.. yeah some hard launches and a trip to the strip with 8 passes. is this a sign of my springs being loose? it only does it then, and i haven't had any other problems with it... besides chatter when it was being broken in. other than that it's fine now.. should i replace it or look into replacing it?

i can't believe everyone is having so many problems.. all the people i've talked to say ACT is the best for DSMs.. i guess their street disc is just a piece of S***. exedy cerametallic the way to go? how's the drive ability with a puck disc? i wanted a daily driver 12 second car.. any one help me out?

 

[laserspeeddemon]

looks like you are in on this too. Thats how mine started small chattering. Then BAM!!! no more clutch. Go ahead and add your name to list now. And I will throw your name in there.

You don't need a puck if you are looking at 12's. Go with the ACT2600 Plate and Excedy disc.

 

[95GSXBLUR]

so should i put the car down and not drive it until i can drop the tranny and put in a new disc?

i'm already having trouble with my transfercase too.. anyone know where i can get one of those? thanks -

I wished I'd seen this thread two weeks ago. I'd have saved money and time trying to diagnose this piece of crap.

I had a DSM guru install this 2600 with RREs flywheel, new TOB and RREs line. It worked fine for 800 miles, I was breaking in a new motor so I just had 8 lbs boost, no launches.
Then in Dec. I parked the car to do some more mods and fired it up two weeks ago. The car woudn't go into gear, I thought water absorbed into the lines so I bled it, nothing. Got a new master and did Taboos mods to it, nope. Installed a new slave and bled TWO pints of fluid though it. My pedal assembly is fine, and I've got the master rod adjusted so it releases pressure at the top of the stroke. In other words, everything but the clutch is working perfectly. After all that I could just barely get into gear so I took it on a drive to try to break it loose. Guess what, it slipped so bad I was killing mosquitos with all the clutch smoke. So this babied clutch with only 800 miles on it wont fully engage or dissengage. I AM PISSED

Pressure plate. 3 fingers are about 1/16" further in and 1 is 1/8" further. it's got a big burn spot right where these fingers are. The clutch springs are ok but it's worn halfway to the rivets because of all the slippage. What a POS. :thumbdown

 

[Morphius]

This is interesting. I've got a 2600 and street disk with over 50K on it so far with absolutely no issues. It's still got atleast another 50K left in it.

 

[JASON ROSARIO]

Well I ordered my Act 2600 it should be here tommorow. I'm not going to beating the crap out of it yet because I will be breaking in my motor. I'm praying that this doesn't crap out on me or you will have another name for your list. But until then I'll be saving my pennies just in case.

 

[ShapeGSX]

I've never had a problem with any of the ACT 2600s and street discs I have had on my car. I've installed 3 of them, and each one puts up with a remarkable amount of abuse.

There is a lot that can go wrong with a clutch install. There is a ton that can go wrong with a clutch line bleed. You have to bleed the master cylinder, then the clutch line, then the slave cylinder, and then the clutch line again.

All I can can say is good luck with your fourth. I really doubt some midnight gremlins went out while I was asleep, removed my trans and reinstalled my pressure plate badly. But you might be right. Maybe I should leave a service manual out next to the car for them next time.

 

[ShapeGSX]

Did any of the pressure plate bolts loosen up? That would account for the staggered clutch fingers.

And like I said, bleeding the clutch is difficult to get right. I've had clutches that disengaged perfectly until one day when they just stopped working. Bleeding again helped. There was air in there that got jostled around enough during driving to get into a spot that mattered.

Then I figured out the right way to bleed them, which is a royal pita, but it works.

No, they all were tight. I looked for something that might have fallen into it but I couldn't spot anything. It was professionaly installed too. I'm not the only one with a failed ACT PP lately.

Sorrry I got sarcastic on ya, I'm pretty pissed at ACT right now. Evidently they're blowing people off too.

 

[RoasT BeeF]

Well new clutch and TOB are installed and no more noises. I am just glad I caught it before a spring popped out and ruined my flywheel.

 

[GSXlaunch]

Its comical that I did not notice the problematic thread(s) on ACT until after I shelled out $600 for the ACT 2600 with performance disc and Fidanza flywheel. It seems, from reading some of these threads, that 10K miles is all I will get out of it if I am lucky. Since my car is only set up for racing, it will probly take about 12-18 months to get that much mileage out of it. I am little worried now since I will be launching at or above 6k rpm with the lighter flywheel. I did not upgrade anything else. So my fork, clutch, all linkage, adj rod, and slave rod are 100% stock. The only thing I did was pivot the ball on the clutch fork with a head bolt washer. I have not driven the car with the new clutch yet as I am installing a new fmic, but I can tell by just sitting in the car and pushing in the clutch pedal that it takes a ton more effort than before. I know this is a little off topic but does this clutch set up require modifications to anything else in the clutch/drivetrain?? Thanks fellas...

Here is a pic of my disc and fidanza flywheel. I suposedly got the "performance" disc and it has all metal springs...

[95GSXBLUR]

Alright guys - everyone that hates ACT right now don't. it's probably the best clutch made for the dsm and many other applications. mine has held up to about 10000 miles of nasty beatings.. i've only taken it to the track once, but it did 10 5000 RPM launches that day and many others on the street. it's still holding.. i'm just getting a little chatter when you let the clutch out with no gas. it could be a loose flywheel bolt, pressure plate bolt, or one of the springs on the clutch disc itself. all in all, they probably just made a batch of nasty discs, or we got a shi**y one of the batch.. don't blame them.. SH** happens you know? lets just all work it out... if they would compensate us or send us new discs that'd be sweet..

A revised release fork is a good idea for that pressure plate.

Pulling transmissions for most people isn't a small expense. And they aren't compensating most people, they are blowing them off.

BTW: Mine was a pressure plate failure.

Wow, how come the quotation marks didn't divide my post?

 

[95GSXBLUR]

Pulling transmissions for most people isn't a small expence. And they aren't compensating most people, they are blowing them off.

if we work in numbers we could be compensated. Put yourself in ACTs place. if you're trying to make money in a business, you can go replacing parts for everyone that has a problem. I'm in the same boat dude, i'd like to get my parts replaced as well eg. clutch, flywheel, but they'd lose too much money shelling out $600 a person that has a problem. it all comes back to money.

I know it's hard for most people to pull tranny's but if you own a DSM you should know things are gonna break. you should learn how to do this stuff, and if don't wanna learn, or don't have a place to work on your car, nor the money to, then sell it to someone who does.

sorry to be a dick, but once you start modifying a car, things will go wrong. if you're not prepared to deal with it, then you're at fault.

 

[GRNDSM]

I still believe that ACT hands down the best clutch for DSMs!!! But they are not without faults… It appears that they have some manufacturing issues, which they are blowing off as customer’s faults. And that is NOT RIGHT.

If they continue to mistreat their customers, their image will suffer and it will eventually reflect in their sales. I just do not know how to make them see this…

However, as it stands, I am still using their clutch…

My lil bro has a ACT 2600 on his RS and have never had a problem with it. His car has always had a steering problem so we pulled the tranny out to find the Disk and everything was in good condition but we did find something not so cool....one of the prior owners fo the car was 2 cheap to but a LSD so he just welded the differentual. that was fun my bro was so pissed he chucked a wrench and it hit my dads GTO....Wich thank god dad is in the process of pulling dents any way......I was like NOOOOOO as it headed twards the car in slow motion and left a big dent....Any ways no problems so far with the Clutch but ill tell my lil bro to keep an eye out for the problems u guys have been having.Im a little hung over sorry for any spelling


O the reason we were pulling it all out any ways was we were putting in a LSD

 

[bigfoot]

sorry to be a dick, but once you start modifying a car, things will go wrong. if you're not prepared to deal with it, then you're at fault.

I had the boost turned down to 8 lbs to break in a motor. And I'm at fault? One of the dividers between the fingers bent over and three fingers were jammed inwards. After 800 easy miles at 8 lbs boost with no launches? No dude, that's ACTs fault.

Yes they are running a business, well the product they sold me stinks. I'm a consumer, I buy from someone else next time. They have competiters, check out RPS and South Bend Clutch.

Most people are having disk failures, a few disks are much cheaper than a companies good name. Is that smart business management?

Oh, and I can swap trannies just fine. But I spent time and money replacing a perfectly good master and slave because I was sure my almost new clutch wasn't the problem. I almost spent five hours ripping out my pedals even though they have very little play.

I'm done with ACT. If they don't respect thier customers then they can go to hell.

 

[95GSXBLUR]

well i'm sorry you got the shaft dude. everyone else on here has only had a problem with the disc. and there are many contrbiting factors on why the clutch could fail. i'm not doubting you, your skills, or your car, but is it possible it was installed wrong?

your case is pretty extreme - everyone elses seemed to have a beating before they went bad. in your case that's obviously not it. i wasn't refering only to you.. but to everyone who has a problem with ACT.

i'm sorry for your unfortuate case. good luck with your DSM dude..

Thanks. The car will back on the road soon, and I will get over the anger as soon as do that first good pull.

The clutch was done by the guy most in the area say is the best DSM mechanic in the NW. I've read of two other pressure plate failures on this board lately so I'm not the only one.
