I would really stay away from that. One good thing to think about and know is that jhm actually has a S5 that shares very close to the same idea flywheel as the S4. So jhm tests and has been testing this clutch for years. It’s the only company that can test and test.
I am still on the fence but at this point I have two options:
- Resurface my stock FW and use a stage III/IV clutch from JHM or EC. A guy on Audizine bought a new oem FW as well as stage IV JHM clutch and raves about how easy it is to drive.
- Buy a LWFW + Clutch from JHM or EC but I am reserving judgement on that until I can actually drive a car with a LWFW in it. Hoping to do that tomorrow.
im kinda on the same fence you are. I was going to reuse my stock fly, but i keep hearing warnings that it is a “one time use” flywheel. I think that is still only because some machine shops dont know what to do.
I am going to go with a lw flywheel, as a new stock one is almost the same price (600 on amazon)
I have driven cars before with lw flys, and as they are not my first choice for a daily car, they just took getting use to to get over it.
I heard that too but my shop swears they have a place that can do it so we’ll see.
Where are you seeing a LWFW for $600? EC is $800 and JHM $1200 and I don’t know who else even makes them for our cars.
On my B8 i had my stock flywheel machined and i ran it with CM FX400 with no problems. Stock flywheel had 50k on it when i resurfaced.
Solid man. I have 11k on mine so I should be ok.
There is no chatter
Pedal is even better than stock
Engagement point is as smooth as butter
When I decided on the JHM setup I was ready to accept the possible chatter, heavy pedal, and rough engagement point for performance…I was SO surprised that there was none of either of the three things. In fact, each of the above three were ALL much better than stock!
This thread should be closed by now. This is a no brainer.
I noticed your sig mentions APR stage 3. Do you have a 1320 or 1740 on your S5? Reason I ask is that JHM do not recommend any of their clutches with a 1740.
Thanks
^^ Welcome. And 1320.
Troll? How about you introduce yourself since you’re so well versed in JHM recommendations.
On Topic- a 1740 kit doesn’t exist for the B8S4, so that was a pointless comment.
1740 Topic- The JHM 5R series clutch package was used on the APR 1740 hailmary car, which made multiple low 11sec passes and some high 10sec passes on drag radials…I think you’re getting bad info from somewhere. If JHM clutches hold JHM power, I’m sure they can handle anything else thrown at them.
Hey genius he has V8 S5 …http://goapr.com.au/products/stage3plus_b8_s5_42fsi_au.html and he is specifically referring to the JHM LWFW + clutch, not the 5R. Which to the best of knowledge hasn’t been released yet.
I drove B8 S4 with a JHM LWFW and stage III clutch this morning.
Throw is most defiantly shorter than stock by a long shot. Clutch pedal is stiffer and takes more leg muscles to engage. I didn’t noticed the RPMs moving all that much quicker and I heard no chatter whatsoever. However the owner said that he heard it at one point but it seemed to go away. I tried to make it chatter by 4th gear low RPMs and idling it but I couldn’t discern anything. He also told me it cost me $3800 all-in and has had it for 10K miles or so without issue.
In the end it was fine for the most part, the two things anyone would notice is the throw and stiffness but other than that it seemed fairly street-able.

Wow…genius, thanks.
I know what Supercharger and car bigserve has so pump your brakes. This whole thread is about your aftermarket clutch decision for your B8S4 and you are only worried about stage 2 numbers, right? So what is the point of the troll comment made by this Whiteq with his first post. The 1740 doesn’t even exist for you so his JHM comment is irrelevant.
Just forget my R series talk, the point of that clutch/new PP design is to rid the B6/7 of the OEM SAC system and increase clamping force. The B8S4 doesn’t have the SAC system and JHM kit apparently upgrades the clamping force with an OEM PP. So the R series will probably not be released for the B8S4.
What do you mean by “throw” in regards to your JHM LWFW test drive?
[quote=“euroswagr,post:54,topic:6446”]
It was a compliment.
I am not talking about bigserve I am talking about whiteq having a 1740 kit on his v8 S5. The JHM LWFW and clutch will work on any B8, not just 3.0T B8s. So yes not apples to apples in terms of power but its the same parts.
When I say throw I mean how far you have to depress the clutch to have it engage, its almost half or less than the travel compared to OEM. It felt like almost a quarter travel where as the OEM you have to press it to the floor. Is throw the right word to describe this?
I have no clue who the whiteq guy is, sorry. I didn’t even know the 1740 kit was released to the S5s.
I guess throw is ok, just can get confusing with shifter “throw” too.
I would call it the engagement point, and discuss it relation to the pedal.
So does the clutch engage closer to the floor or further up off the floor? It could have a lot to do with the clutch disk thickness. Maybe it’s because its new or because it has more material than OEM.
Good question and honestly I I probably used the wrong terms again. lol
I just know that the distance the clutch had to travel to engage was a lot shorter than OEM. I didn’t look to see if the clutch in the JHM car was touching the floor, it just felt like it was but in reality it was just stopping shorter than OEM.
I asked the owner after the fact and he said “pedal travel reduced, crisper engagement, and engagement point is closer to the top of pedal travel (away from the floor).” I felt all of that when I drove it but obvisouly had a hard time putting it into words.
So to answer your question it engaged much further up off the floor.
Hopefully that helps.
Maybe this is an installation issue? I didn’t notice any difference on engagement point. Maybe Jimmybones or JustinInc. can confirm?
generally when the engagement is lower or higher than stock, or the feel is signficantly ‘un-stock-like’ it means someone fucked up. JHM designs these for Audi drivers…who they know to be a bunch of stock loving pussies (myself included).
Wow, thanks thanks for the welcome…
I’m not going to bother getting into justifying my post with a reaction like that.
