View Full Version : Ok, help me figure out clutch options

Once again, my clutch is slipping. Pretty badly, actually. I upped the power slightly by advancing timing for the cold weather, and the clutch can't handle it. Sure, I can baby it for a week or so, and it might go away for a while, but I am definitely straddling that line of failure.

There are so many options out there, and I need help in figuring out what I need.

My goals for this clutch are:

1) Daily drivability, this is my only car.
2) Good balance of cost/performance. The cheaper the better, but I am not willing to sacrifice performance or longevity for cost.
3) Biggest I every plan to go, is K0R. (guessing roughly 400 ctq/400 chp max)

Other things I'm not sure on. Do I need a lwfw? What are pros/cons of a lwfw? What exactly is this "chatter" I hear about? Am I really looking at paying my shop ~8 hours to do this?

I have already peaked about 385 wtq when I hit peak boost at ~3200 RPM, and that is what is killing my stock clutch.

Options:

Vast, 034, Clutch Masters, South Bend

What's good, what's not? What stage do I need? Lwfw? Any input is welcome!

Jim, I have had the ClutchMasters FX400 clutch now for about 30k and have never had one bit of an issue with it and using my stock Flywheel....

That's the kinda stuff I'm looking for, Jeff. Thanks. I assume I would have to resurface the stock flywheel?

There is chatter and then there is gear rattle, problem is some people say chatter when they actually mean gear rattle.

Gear rattle is the sound of the gears inside the transmission spinning, that sound travels thru the input shaft of the transmission. The dual mass flywheel soaks up that sound, the lighter the flywheel the more you can hear.
Chatter is the sound of a disk skipping off the metal surface of the flywheel or pressure plate as it is being enaged from a stop.

LWFW will increase throttle response, the dual mass flywheel tends to cause rpm hang when shifting at higher rpms and the single mass flywheel will remove that because it is 1 sold flywheel.

For a normal driver you can go with a stage 2 or stage 3, but if you ever plan on launching your car or driving it hard then you will want to go with a 6 puck ceramic disk or something equal to that.

Most definatly need to have the flywheel resurfaced.. If anyone says you dont IMO they are wrong as the surface will not be a clean mate to the new clutch disc causing premature wear.

How much does resurfacing cost? I'm assuming the FX400 is more than I need. Looks like stage 2 might not be enough, so stage 3 then?

Should not be more than $50. The FX 400 is good for 400wt so it should be perfect being you are at 380wt+.

Not wheel, crank. Doubt I'll get much past 400 tq crank.

What about Vast's clutches? Doesn't Shane have one? Their stage 3 is on sale for $475 right now. Cheapest I have found the FX300 is almost $600.

That depends. Some shops will charge anywhere up to $300 to resurface a dual mass flywheel. South Bend offers it for free when buying one of their clutch kits, you just for the added cost of shipping the flywheel back with the clutch kit. CM will also do the resurfacing when buying one of their clutch kits, around $50 to cover the labor and adding shipping cost when shipping it with the clutch kit.

I Have the Vast stg 3 which is one of the other popular clutches on our platform, it was an awesome deal, easy install and a very very smooth oEM feel. This is a car that is primarily driven by my wife during the week and she had no issues with the difference in feel. I've been to the track and it has held launch after launch.
No chatter, no install issues.
I have driven a few clutchmaster setups, those were some Gnarly setups, but felt very heavy and had some chatter. I think vizi and a few others have no chatter!? But for me the vast clutch was a no brainer.
I believe Jmarch has it as well :-)
A resurface should be anywhere from 50-75$ and is highly recommended.

jimrobbington
12-10-2011, 09:55 AM
Well, rkesh, Elite Motorsport gave me a "deal" of 700 shipped on the FX300. Not a deal at all.

The FX300 sounds good, but its hard to beat Vast's price. I just dunno. I know Jeff isn't the first to have problems with Vast, but is it worth it to spend more just to not support a so-so reputable company?

u know my vote: customer service comes first

luckily i still have some life left in my clutch, but i've been doing some research on clutch/flywheels as well. how loud is the "gear chatter"?

b/c I definitely want to get some better throttle response and have my engine speed drop faster in between shifts, and always planned on getting a lwfw just not sure eaxctly how annoying the noise is. if i understand it correctly does it depend on the shape of your transmission?

If your worried about customer service send an email to [email protected] and ^see how much he's willing to help you. I was the test dummy for the clutch. I paid 570$ for it so don't think I got a deal. They sent me two pressure plates, custom made a different slave rod and were in the phone
Making sure I had no issues, they even helped me out a great deal by discounting a lpfp upgrade and helped me
With tuning software. That's alot more support than most other companies offered, and between them and ray at RAI I've got nothing but good things to say so far.
I will say that chatter and feel are the only things I've heard about the clutchmasters setup. They are def proven clutches and some people get chatter and stiff feel while others seem to have no issues. I drove on a clutchmasters fx400 in my friends Vw and thats what made me choose vast.
Good luck jim

I paid 750 shipped for mine, It just depends how much time you have to find the best deals and if you can wait until that deal comes along.

Not to put SB down but I have read many threads on failures now it may be due to install error but it seems like quite a bit of issues with SB clutches. IMO!

Last time my clutch started slipping was about 10k ago, but I hope to go 2+ next year and if just adjusting my timing by half a degree added enough power to start it slipping again, I figure I better do it. Plus I can tell my wife it has to be replaced for maintenance.

Im running the 034 stage 3+ clutch and LWFW, got the package of their sale a while back for 750 total.
I really happy with it, the downside was that its a really tight fit when installing. I actually had to use a small dremel kinda tool with sandpaper to make it fit. ( yes hard to explain when i dont know what the tools are called). Anyway its my daily drive as well. The only thing i can say that is different is vibration in the car when at low rpms i 4-5-6th gear and accelerating. Really happy with it :) good luck on finding your setup :)

I bet oem would be more expensive than aftermarket. But the stock clutch typically has incredible longevity, especially for what we do to these cars.

If I were to resurface my OEM one, which is the MUCH cheaper route from what I understand, will I need to replace any other parts? Won't that be no where as good as replacing the entire assembly?

You will need to inspect your stock flywheel before having it resurfaced, you need to check to see how much play there is with the section that rotates. If the spring inside gets too soft there will be too much play and you will want to replace it before it fails.

That is pretty awesome. I got the VAST Stage II clutch and their 19 pound single mass flywheel on the way, so I am thinking over my options. I don't think I will be pulling it off myself, and will just pay the $650 in labor for the piece of mind. I also have a custom 034 made high flow CAT with an S3 flange mated to it sitting in my garage, so all I need is 034 to fabricate up the new motor mount for the S3 k04, and about a weekend and a six pack to get most of the setup rocking. I am about 2.5 hours away from the nearest tuner (APR in Portland), so I am going to run stock injectors and 2+ file until I get a chance to take a day off to drive up and get my car flashed. I really wish there was a quality tuner out there that had a kit to flash your car at home with files they sent you. I thought GIAC had a flash loader for this, but they don't show any application for the b7 a4 with a k04 http://www.giacusa.com/programs.php?mpid=494. If anybody knows a tuner that will sell you their tunes to flash at home I would love to know. I have been talking to VAST the last two days about my clutch options, and starting to really like that shop, so maybe I can see if there is someone close that they can have me flashed.

What you do is they tell you there is a revision so you then plug in the OBD flash tool then vpn into vast then log into the flash tool application which is connected to APR's server (affiliated) locate your file then upload it to your car and your done. They say to make sure you have a battery charger connected to your battery everytime you upload a new revision.

This is straight up the future. Can you imagine if Microsoft had you drive to Seattle every time there was an update?? ;-) That is basically what all the tuners are having you do now.

Now open up the market to 10 times the cars..., and boom, a whole much bigger market of people willing to pay to use your tune. You know why? Cause each time you add something to your car the optimum tune has changed. So start with a base tune specific to your ride and update each time you put anything substantial on your car so that you maximize whatever it is that you just had installed.

I am pumped! I have been talking to this shop for only 3 days, and they are really great guys. Take the time to explain to you what you are working on, and willing to help you reach whatever goal you have in mind. Plus, no trying to push useless items on you that you don't need. Just my kind of shop.
