Spec Stage3+ vs. ACT 2600

[steel_3d]

I'm really leaning towards the 2600 with the organic disc because I've been running one for several years on my old car and haven't had any problems with it (well it might've been responsible for killing the OEM throwout bearing). I think it's very streetable in that it's easy to slip. Don't mind the extra leg workout.

Any opinions on the streetability of the Spec Stage3+? Especially with a Fidanza flywheel. My flywheel was trashed, otherwise I'd stay stock. I can see this thing chattering and being impossible to slip with a light flywheel. Does the disc have the compression leaf springs to ease engagement? (forgot what they're called, I'm not talking about the hub springs, I know it's a sprung hub). I live in LA, so I do a lot of stop-and-go.

I think I know what your talking about but I dont want to post it and look like a dumbass, but if you are leaning towards the 2600, I would go with a sbr 3500, more clamping force and less pedal pressure needed to engage it, probably be better for you in LA with stop&go, long as you stick with a street disc. Im gunna wait and see if anyone else posts and explains what you are talking about, and see if my assumptions are correct to what you are talking about.

I have been using the spec stage 3 light weight version for about 300 miles now. There was a little bit of chattering during the first 100 miles of breakin then it is all gone. I have used both the 2600 and the 3 and def the the spec is much easier on the leg, (don't look bolegged from pushing in the mammoth clutch) I enjoy the spec to because it has a much beeter feel for engagement then the 2600. I felt like i had to just wing it in when i ran the 2600 the spec i can just feel it all the way through the launch. I'm also running the act lighten fly. In conclusion SPEC

Hmm, no chatter with the spec? Interesting. What rpm do you slip it out at in daily driving?

Anyone have any specific experience with the stage3+? I'm guessing the full face disc might chatter less, but dunno.

The sbr 3500 is a good suggestion. Their deliveries take forever though, and I kinda need it right away. #### me... Maybe I just need to tough it out and have my car be down for an extra week... Any personal experiences with this clutch?

I think the spring I'm talking about might be called a wave spring? It's the thing that keeps the two halves of street discs separated when you look at them edge on. It then compresses when engaged. Basically it softens the engagement point.

Not so excited about the SBR 3500 after reading this thread:

Anyone else have more info on its durability?

 

[fourreGsixty3]

Well it appears to be normal wear and he slippes then clutch and has it at the track quite a bit, so IMO it should be a fine clutch for you, aslo my friend nas a spec 3 in his teg and he loves it. Check out the ACT 2900s, they seem pretty good, like all ACTs but then again I havnt lloked too indepth in to them so no clue how they hold or if they chatter and what not.

 

[steel_3d]

There's other people in that thread and elsewhere that had them die right after breakin or after a couple of thousand miles. My 2600 lasted me for years, and I think it was still close to new when I sold the engine, the pedal grabbed just as low as day 1. They seem to last well for everyone.

Still open to opinions and experiences.

I have the regular Spec stage 3. The pedal pressure is lighter than an ACT2100 which I have in my other DSM. The Spec chattered for the first few hundred miles, then it went away. The engagement point is broad, it's easy to slip in stop and go traffic jams, no worries. I drive it to work in rush hour traffic, 70 miles per day and I like it much more than the ACT 2600, which is what I had before I got the Spec. I've had the Spec for about 9 months so far and it's still holding the power just fine.

I have a regular Spec Stage 3 with a Fidanza flywheel as well. It seriously feels about like a stock clutch, pedal pressure wise. But I also have a SS clutch line. It does chatter though, and I'm at about 500 miles. I've launched it a few times, and it grabs very hard. It took a little getting used to since the engagement is like an on/off switch, but I like it. It isn't bad to drive in stop in go traffic though, you get used to it quick.

 

[steel_3d]

Heh, you guys are extreme opposites in your opinions on engagement

I guess noone's tried the stage3+?

 

[Dream On]

I imagine it would be better for daily driving. I got mine from Titan Motorsports, who had it the cheapest at the time. ($300)

Did your Spec clutches come with the OEM style TOB or a metal one? If it came with a metal one, did you use it or get an OEM one?

 

[Brad_11]

As I am putting an ACT clutch in, I prefer the ACT clutches cause I have reliability with them as long as you arent pushing a car that has alot of HP but I have never tried the spec 3 but have "heard it is easier on the leg" also as posted above, but I think it is just prefrence, both are good clutches.

Just an FYI, we have about 40 SBR 3500's in stock right now.

We also have plenty of ACT, and the new Fidanza clutch in stock.

MGH

With my Stage 3, I think the TOB was metal sleeved, but don't quote me on it. I bought an OEM one before it even came in the mail, so I didn't pay much attention to it.

 

[pneumo]

My Spec Stage 3 clutch came with a metal sleeved TOB. I didn't use it. Instead I re-used the old OEM TOB because it only had about 10k miles on it.

 

[PieEyedPiper]

spec stage 3+ > act 2600.
and I had the same questions about the TOB and the speed factor assured me they've never had a spec tob fail. So far mines working great.

 

[steel_3d]

Would you care to elaborate on the supremacy of the 3+?

I would be interested to hear about this as well.

Hybrid clutch setup here Act 2600pp with the spec stage 3 6 puck disc. Working beautifully right now.

 

[4G63 For Me]

I burned ACT street discs out in 4000-5000 miles with very few launches. I never broke the tires loose with this clutch.

Switched to the Spec 3+, it has been going strong (havent put enough miles on it yet to compare, but I'm pretty sure the iron disc will last longer) and the tires break loose before the clutch gives.

I like the Spec 3+ loads better than ACT.

3+ is one of the nicest clutches we have ever used. great pedal pressure and ability to take just about anything you can throw at it. I highly recommend it.

Marty, is that you? So you're with another shop now?

Is the SPEC spring 6 puck disc available separately for when mine wears out?

 

[steel_3d]

Hmm I wish you guys had posted before I bought my act I went with it since it's proven and it's treated me well before. We'll see if it works as well in a 400whp awd car as it did in a 250whp fwd

Do they sell the 3+ discs separate? Might be interesting to run it with the 2600 pp.

How is the engagement with the 3+? Any chatter? Does it have wave springs like the organic discs?

Please keep this thread on-topic with the 3+. I'm not a fan of 6-puck clutches (previous clutchnet), so I wouldn't consider the stage 3.

yeah buddy! Got my own thing going on now.

The discs are available on their own. We have used that 6 puck in a lot of cars and they have taken years of abuse. Street/drag/drift cars alike. I am one of those wimpy whiners that can't take the 6 puck grabbing force because of traffic here and my daily commute but damn it is an awesome clutch.
