By using a heavier Clutch Disc & Pressure Plate this will add 3 more
pounds to the Alloy flywheel (as compared to the OEM 2.5 Clutch Disc &
Pressure Plate ) making it feel like a 13 pound flywheel. This overall
weight reduction is 9.7 pounds. A steel version could be made if the
alloy one ends up being too light and or a heavier version is wanted.

Here are some examples of other weights of OEM Flywheels (Engines of
similar power)
All OEM Single Mass Cast VR6 12V flywheels are 17.75 pounds w/ ring gear.
Many users have switched to a L/W Steel Billet Flywheel that weighs in at 11.75 w/ ring gear fitted.
Also available are slightly heavier Cast steel Single Mass w/ ring gear at 13.80 pounds ( still lighter than stock).

MK4 1.8T W/ 5 speed users are changing the OEM DM 22 pound flywheel
and converting to A Single Mass as well.
Again using the same weight as a 12V VR6 single mass steel billet
flywheel that weighs in at 11.75 w/ ring gear fitted.Also available
are slightly heavier Cast steel Single Mass w/ ring gear at 14
pounds.Both of the these flywheels were created in the aftermarket as a
performance part designed for the Corrado G60 and are using the very
proven Sachs VR6 clutch kit ( this Sachs kit is rated to 250-275
Torque and takes more)

1.8T & 2.8 24V VR6 W/ 6 speed 02M 6 speed users are changing the OEM DM
26.5 pound flywheel to A Single Mass type as well. 16.5 single mass
steel billet w/ ring gear this takes 10 pounds off and does not chatter.

2.5L Stage 2X Clutch Kit

Install photos and sound clips below. Test Fitted and driven Friday and Saturday.

To my knowledge this is the First kit using these parts. I have only seen a box from SB ( no contents or description known) Also heard about another flywheel from BS again have not seen contents or know description of it).

There was a very slight noticeable chatter at idle with clutch pedal out. this noise is no where near as loud a the 9 lb alloy flywheel on a 02m 6 speed. Sounds clips might not pick it up ( recorded on a basic canon digital camera) this will be uploaded later today.

[Lloyd Plumtree]

Any chance this flywheel will work with a 02J/A swap? Guess the only thing to look out for is the starter configuration. How many teeth are on the ring gear... same as 02J/A? Good work guys!

[youngkal]

is the kit that cost $559 the stage one clutch that is rated at 275 fwtq?

[FourSeasonTuning.com]

Thanks for the bump.

Can count the ring gear teeth on Monday. As far as an 02A/02J swap, The height of the ring gear and the overall stack height on the 2.5L is much different than the 12V VR6 / G60 flywheel and clutch setups. I would try the the single mass set up like this
http://www.fourseasontuning.com/?product=101 as it works with the 02A/02J for sure.

The general rule of thumb has been use the flywheel/clutch kit/ starter that was designed to work with the transmission code regardless of the engine. Most VAG flywheel's have been 6, 8 and 10 hole at the Crank flange. For example the step and stack height are the same on the 02A /02J. The 6 hole flange is used on the 4 cyl and the 10 hole on the VR6. Same goes for the 02M six speed stuff the 1.8T and 2.8 24V VR6 are the same setups except for the amount of holes in crank.

The 2.5 5 speed is very similar to the 02J.

[FourSeasonTuning.com]

Yes.

I am confused with this flywheel stuff..

Dual mass flywheel= externally balanced engine?
Single mass flywheel = Internally balanced engine?

So some years have an externally and internally balanced engine?

[FourSeasonTuning.com]

The dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle. The unit is split into two sections: a primary section that bolts to the crankshaft, and a secondary section, onto which the clutch is bolted. The primary section dampens, isolates engine vibrations.

VW has be building internally balanced engines. High CI V8 are often externally balanced engines.

If you're rebuilding an engine that is internally balanced, the flywheel and damper have no effect on engine balance and can be balanced separately. But with externally balanced engines, the flywheel and damper must be mounted on the crank prior to balancing.

Guess I should have stated some more info. I`m planning to mate a 02A trans to my 2.5L motor (which is going into a MK3) I`m aware of the flywheel/crank bolt patterns. Just wondering if a 2.5L clutch kit will be needed to complete this conversion. Guess I`ll just bolt it up and see what I come up with.

[FourSeasonTuning.com]

I would use the G60 flywheel and VR6 clutch as it works with the 02J. Compare the height off the crank flange and flywheel ring gear position.

[2ohgti]

It is good to see a flywheel available

Thanks for the bump. We have two types now, Steel Billet and Alloy.

[slomk5]

just bought this kit yesterday.. hopefully its not too good to be true

[4door1.8T]

Awesome this will have to be one of my next mods

[FourSeasonTuning.com]

Shipping today, thanks for your order.

[slomk5]

quick question.. are those included bolts for the flywheel or for mounting the pressure plate

[FourSeasonTuning.com]

Both are included.

[slomk5]

sweet.. one less stop, btw are the bell housing bolts triple sqaure?

i plan on doing a writeup for the install

From this I gather that the vR6 clutch will work with the OEM tranny in a 2.5L MKV...if that's correct....do you have torque ratings from Sachs for the Vr6 clutch vs the OEM MKV 2.5 clutch?...Thanks!

[FourSeasonTuning.com]

Not sure if LUK has released the numbers on the 2.5 kit. The Sachs kit has been widely advertised at 275 Torque (many turbo VR6 users are taking the stock Sachs beyond that ).

[visdsinerie]

Changing from a DMF to a solid damper would effect the torsional vibration levels of the crankshaft resulting in different crankshaft stresses. It would be interesting to see what impact, if any, the change to rotational inertial and damping rate on the drive end of crankshaft has on overall crankshaft stresses. I imagine there is healthy fatigue margin in automotive crankshafts since crank failures are extremely rare in automotive applications running at rated powers. Being involved in large Diesel engine development and worked on crankshaft torsional testing this is not something I imagine aftermarket suppliers have the resources or testing equipement to measure but in the off chance this was done would be interesting to see the plots

[Corruptkid]

got my set of stuff yesterday, thanks james

what applications would you use these for? Why would you choose alum over steel?

[FourSeasonTuning.com]

For the most weight reduction people use alloy. The steel is a bit heavier and is a stronger. Both are designed to work on the 2.5 when combined with a 228mm VR6 clutch kit.

this is worth the money, just finished the 500 mile "break in" period, it feels like a whole different car!

for reals? Cuz the one thing I despise about the 2.5 is the effin clutch. It has zero feedback and I stall it more often than my 96 GTI or 92 Golf (which is like never) and there is like no in between on the 2.5, in or out. I hate it and anything I can do to change that is worth it in my book.

[~kInG~]

in my case I feel the car is easier to launch and shift

[5_Cent]

thanks I just want to feel the clutch more anything else is bonus.

[vw93to85]

I got 600 miles on mine. I'm gonna wait till I hit 1,000 miles and do an oil change before I really start hammering on it. I've laid into it a couple times in the past few days and it feels great. The clutch pedal feels like something is actually there and the shifts feel so much better.
