The Alloy subframe fits most MQB cars including the Golf R etc... The only thing that wont fit on the Superb is the Alloy LCA's for the Golf. I've been running the ally subframe for over a year now with no issues, with B16 DCC coilovers, Whiteline Front and Rear ARBs and droplinks.

I always thought the low speed noise was the top strut mounts which I've just bought and was planning to replaced them.

Also once you've installed the B16 DCC remember to recalibrate the DCC values via OBD11, I didn't do that at first and the ride was firm, once calibrated it was much better.

Cheers @Awesam - yep calibration will be on the cards afterwards for sure. The guys at the Phirm are switched on having done these all the time.

Just need to go through and make sure I’ve got all the necessary side bits - top mounts, bearings, maybe bolts and all that sort of thing

Did you look at the Passat parts for an alloy LCA? Possibly part code 3C0 407 151 ??

+1

sub-frame is same same.

lower control arms (LCA) for the Golf is short, i.e. not wide enough, for the Superb.

i don't know if the Arteon, or even Passat B8, have the same LCA as the Superb, or use the Golf version.

Edited 18 August, 202518 Aug by JR RS

Turns out the Superb mk3, Passat B8 and Arteon 3H7 all share the same LCA.

Great Minds @ John, I was literally doing the same thing earlier!

So how many complaints of excessive road noise can you find about Passat B8 or Arteon?

Is the all alloy fronted the difference?

I have combed thru the difference between the models on the mqb platform which can cause noise issues, this is the only difference that isn't discussed.

Is there any acoustic variants for the Arteon and Passat?

@DrAvalanche - not sure if u were asking me that question, but in any case - no idea.

I was just confirming that the Superb shares the same LCA as the Passat & Arteon.

I've read many posts where Superb owners have installed the LCA for a mk7 Golf thinking it's the same, cause same sub-frame, but ended tracking wrong, and the wheels sitting more inward.

I myself would've like to get the aluminium alloy subframe, as well as aluminium LCA for a Passat/Arteon....one day.

I was asking for whoever can answer lol.

Bare with me on this🙃

The wife's 2016 Octavia 1.2 petrol on 16" wheels is far far quieter than my 280 4x4.

The thread on the forum here for sound deadening is quite comprehensive - wheel arch liners, wheel arches, bonnet, all under cabin floor, doors, door cards, B pillars. But apart from the B pillars, all the rest is what you would do on any other car.

There's no NVH dampeners available for 4wd Superb, just the one part available for 2wd cars for the rear subframe.

In fact, I cannot find any NVH dampeners used on any of the MQB platform.

So how can the Passat and Arteon be a more premium model if they have tyre noise like the Superb? They may have more sound deadening than other models, but it wont be to the extent of the amateur modder will do.

From what I can see, the Arteon only comes with the alloy front subframe, no steel option I can see for sale. I would like to think this is the difference for a quieter vehicle.


@MartiniB thought you may interested in this thread.

Audi inject cavity foam at the factory as part of the build to reduce road noise and make the vehicle feel and sound quieter.

Maybe this is done to a lesser extent on the Passat and Arteon, and not at all on the Superb?

@JR RS From the LCA parts list for the Arteon I looked at, they were made out of steel, I couldn't find any which were made of aluminium, even checked the Super pro website to see if they offered any but sadly no.

As for sound deadening, I would say that VW/Audi definitely have more premium sound deadening than the Superb even it's better than most models. Behind the door covers there is one thing sheet on the inner door skin and there is some foam on the wheel arch liner along with some in the roof liner and under the carpet

Superpro do have alloy for Superb LCAs. However...only seem to be upto 2019 so pre-facelift but I didn't think there were differences to FL (although MQB/MQBEvo), they're £800 without bottom ball joint, and they increase caster so won't be OE replacement setup.

If ur referring to ALOY0018K, then sadly that's the wrong one for the mk3 Superb, despite some websites saying it's compatible with the Superb 2012 to 2019. That's covering both the MK2 (3T) and MK3 (3V) Superb series!!! Really SuperPro website!?!?! Both r completely different platforms!!

It's right for the mk7 Golf, but short for the Superb.

I know of 2 or 3 Superb owners who tried to fit the Superpro alloy LCA, only to find it not the right fit.

I wouldn't recommend buying the Superpro ones.

Not seen any aluminium control arms for the Skoda Superb MK3, they only do OE steel ones with ball joint. The aluminium ones are for which for the MK2 Superb model 3T based on their part finder.

Yeah you're right - This one is indeed ALOY008K. Selected from Superb, but for compatible vehicles it then doesn't list the Superb. Amateurs.

Hi , What do your Insurance company say about such a modification ?

Phone them and ask

It's mod with zero performance increase. However gives them an excuse to charge you more.

My car is heavily modified so my insurance premium is high.

My Superb is lightly modded, but all mods declared. Insurance is cheaper than going thru mainstream insurers and not declaring mods.

My previous modded car is a Mk2 MR2 turbo with practically everything upgraded or modded, 350bhp, insurance wasn't particularly expensive on that.

My age and a somehow clean licence helps probably.

In the UK, do you guys have to notify your insurance if you fit an aftermarket spare part not OE?

I mean if I have to replace an LCA and instead of putting a Skoda one, I fit a TRW or Lermforder or whatever, if I call my insurance broker to tell him about it, the level of cussing for wasting his time will be memorable .... and same would be if I get same LCA "compatible" for the Superb, say from an Arteon.

Just asking .... different places, different norms.

I can understand if mounting a metal bumper with a winch on a Landie, from a insurance vs. third parties perspective, but ... for spare parts?

Not if it’s OE spec - pattern parts are used in non-dealers all the time and they’re designed to do the exact same thing.

Even something that was originally designed for an Arteon, if it’s within the same tolerances and there to do the same job then I don’t think it’s an issue - i.e. the rule of thumb is if it’s not there to change the performance of the vehicle then it’s not an issue.

2 things come into that though -

what defines changing the performance of the vehicle - engine output is an easy one as it’s definitive and measurable but something more subjective such as OE size brake pads of an improved nature may mean (a) nothing at all, (b) that the driver requires something to stop better so perhaps he’s driving faster (c) that the driver merely wants to have better braking as it’s increase safety. Entirely down to the insurer which way they want to look at it.

Which is the second point - it’s all speculation when in reality it also depends on the insurance company, what their risk modelling is, what they profit margin is, how they view drivers as opposed to vehicles etc.

interested, interested,

just have been adopted to that during 10 years with this body🙂

7y 2016. Mk3 220ps FWD and third with 2023. Mk3.FL 280ps AWD

and upgrade seem costly with no guarantee of success

also, if touch this position, then logical addition will be aluminum arms, which for non lowered?

have you add lot cheaper things, like additional rubber sealants?

before vs after ( profile D )

profile Z

Those profiling I must make sooner or later ... before winter at least.

Funny how I did some work on older Mercs and they all have those ... amazing.

Thanks Lee for the explanation, probably if the insurance agent/broker has a customer "profiling" capability then what you say could affect favourably - or not - the premium. They've been thinking for years to do this here but yet is not in effect, which for people like me affects me negatively, as I have more than one vehicle but my (scratch balls) stats are very on the "safe driver" side ... 🤨

JMO, but it appears to be a total waste of time and effort, as there doesn’t seem to be any real performance improvements, just the introduction of a load of annoying creaks and clanking. And, no doubt, it cost a bloody fortune too?

Got an update from my tuner when I asked about the clunking with the alloy subframe, the solution is to replace all 4 subframe and the 4 ARB's bolts.
