2G Stage 4 XTD clutch or ACT 2600

[bsbllfit7]

xtd stage 4 all the way. I went with the unsprung clutch and a lightweight flywheel for under 250 dollars. I installed and engagement was quite harsh for about 700 miles tell the clutch wore in now it is just a tiny bit harsher engagement then stock though. My girlfriend can drive the car just fine and this is her first manual car. holds up just great on launches too!

XTD4 is leaps and bounds above the 2600.. I believe it is closer to the 3200. If you are looking for a 2600, the X4 is beyond that range how ever clutch pedal feel is similar.

The XTD Stage 4 is actually only a 2300lb pressure plate. The reason it holds so well is the friction material. The more you abuse it the better it engages and holds. It is not an organic material that loses grip with heat, it is metallic and heat causes it to engage quicker to a point.

Now that makes perfect sense. That would explain why people are having it hold up to hotlaps/abuse better without slipping while retaining a pedal with less required pressure than the 2600.

 

[bsbllfit7]

now that makes sense why it holds better than the 2600, drive-ability is better and the actual composition of the clutch surface is better.

Wouldn't that be a little harder on the pressure plate and flywheel since the friction material is metallic instead of organic? I mean, wouldn't it shorten the life of both the pressure plate and the flywheel compared to being used with an organic type like the ACT street disc?

It is harder on the pressure plate and flywheel. Almost always with a metallic disc, you need to resurface the flywheel and replace/resuface the pressure plate due to the amount of wear from the disc. You won't typically see the "glazing" on the flywheel that you would with an organic disc on a metallic one. Although they do glaze slightly, they usually turn the flywheel blue/purple fairly quickly.

Xtd stage 4 unsprung, i love it more than my old act 2100, pedal feel isnt harsh at all. Holds up strong to all my launches. About 4 k on it and going. Would recommend

It works like this. Racing parts aren't made to last 100,000 miles. They are made to do a specific task that stock parts cant do, for a shorter duration. A stock clutch can last 100+k, but also can be destroyed in 5 minutes on a high hp application. A Puck disk may only last 10-20k, but will not fail from launching.

probably one of the smartest things i've ever read on dsmtuners

I was referring to its holding ability, not the pressure plate clamping force. That's like arguing over whether Kelford272s make more power than BC280s. Advertised numbers don't always have the same meaning. I'm pretty sure it tells you its a 2300llb pressure plate right on the packaging when you get it. Its probably on the item descriptions as well.

However it also list tis ability to hold over 500hp/tq.

I've got 3k on an XTD stage 4 unspung in my daily. Can't beat it for the price.

 

[stevetalon]

Love my stage 4 too. 1k on mine and holds all the power that my hx35 is putting out on 32psi

 

[bsbllfit7]

is everyone else having a similar pedal to stock after the break in in period on these xtd 4's? mine started harsh but now is only slightly stiffer than stock

 

[Bricktop]

mine got a lil easier. not much though.

 

[bsbllfit7]

hmmm weird i no longer have any chatter practically unless i engage reaaaaly slow at a low rpm and my pedal is almost like before the clutch kit was installed.

See thats so funny you say that, because my act 2600 lasted 1000 daily driver break in miles with limited boost and slipped while boosting. My newer XTD stage 4 has less pressure on the clutch pedal, feels better, bites harder, doesnt slip, oh yea and was less than half of the act (which broke the spline teeth off the middle) plus at 1500 miles it has already outlasted the act which makes it a win in my book.

Please dont post hearsay, if you dont have experience with the product then dont talk.[/QUO

The reason I say there "junk" is bc if you do a little research on them sooner or later you will find that people have ordered the stage 3-4 clutch kit and wonder why the pressure plate feels like stock if not less. And someone actually had the pressure plate tested and it was actually 50-100lbs less pressure than stock, and all XTD did was "spray paint" the pressure plate red and slap there "XTD" sticker on it. It was suppose to be a 400hp capable PP. IMO thats not a honest company and I sure would not spend my money on.

I dont care what anyone says, I believe you get what you pay for. And no matter what company there are going to be failures.. Some more than others

Research isn't googling on the interwebs. Research is having a 2600 street disk, and xtd stage 4 in the same car, that traps 100mph in the 1/8. The xtd stage 1-3 are a stock pressure plate, i have never vouched for them, because i have never used them. I have used an xtd stage 4 on many different cars, from stockish, to full out 38 psi ethanol monsters. They work. Stop spreading misinformation, you have never used an xtd stage 4. What you have heard on the internet about their other products, has nothing to do with the stage 4, or real life, for that matter.

I don't understand why everyone likes Street Disks so much. If you push them hard they glaze over, then you have to drive around forever to unglaze them.

The XTDs are great as long as you don't exceed the recommended torque.

I have a XTD Stage 3, wish I went with a Stage 4. But have had zero problems. Its not like a on/off switch at all, I have no problem staying stationary on steep hills. And it grabs hard when it needs to.


If I had to do it over again I would go for a XTD Stage 4 for under 450 ft/lb, or a Twin Disk if over 450 ft/lb.

Either way you go, get a OEM TOB.

I feel the same way, the street disc is junk if your going to drag race, my street disc was good for one hard AWD launch, no joke.

I just got the ACT MB1-XTG6 clutch kit (2600 pressure plate with 6puck sprung disc) in the mail today, i will try to give feedback soon but it will take alittle while to break in first.

How does it have "nothing" to do with real life? WTF or the stage 4? Its the same damn company that makes 1-4. And I'm not spreading misinformation by any means. I was just letting the thread starter know MY POINT OF VIEW. Bc that 's what this site is for. Not everyone is going to agree that the XTD is the best clutch. You have your point of view as I will have mine.

Don't knock it till you try it man. We put one in my buddy's car and it's been working out great. Also the PP definitely isn't stock and "spray painted", maybe for some other cars, but not for a dsm stage 4.

I'm not trying the turn anyone away from buying one I was just saying my opinion that's all. There's been plenty of people that have had both ACT and XTD and hated or loved it. Me personally I like Exedy. But between those 2 brands I choose act. I'm not trying to bash..

 

[forumboarder154]

XTD4 no doubt. Don't pay for an overpriced 2600.
