Title: Passat alloy wishbones to mk5 hubs
Post by: Christiank on May 13, 2018, 08:00:32 pm
Hi guys..

As some of you may know I'm currently having the Passat alloy hubs along with the Passat alloy wishbones.. But to my surprise this setup will not fit with the Vagbremtechnic adapter kit that allow me to fit the Porsche 986/987 calipers...

checked the Vagbremtechnic website and the kit that I've bought for the mk5 has the same item number as the one they state will fit the Passat 3C/B6?


Anyway, guess I'll have to swap back to the standard mk5 front hubs to make this setup fit - Do I have to swap out the alloy wishbones to or can I use these with the stock mk5 hubs?

Was looking at the Passat hubs upgrade this year   I already have the 986 ready to go :thinking: :thinking:

Well don't continue hunting the hubs before I get an answer from Mike at Vagbremtechnic about this mate.  :chicken:
Was surprised aswell that this is not fitting together.

So guess it has to be the Audi TT wishbones, hubs and steering rack with the Audi TT adapterkit from vagbremtechninc since these have a different design and should fit?  :confused:

Guessed having the Passat wishbones and hubs wouldn't give any complications since the mk5 adapter kit is the same for the passat :sad1:

Talked to Mike at vagbremtechnic about this, and he have ordered a Passat alloy front wheel hub to see how to solve this problem in the future.  :congrats:

Anyway, guess I'll have to change my setup to stock mk5 hubs and alloy wishbones.. I think it wont be an issue sine the track from the passat alloy hubs and wishbones only gives 2-3 mm more at each front wheel, where the Audi TT gives 22-23mm more each front wheel

I'm fitting the Passat wishbones and hubs and my Vagbrem adapters fit fine. I'll try to dig out the part numbers so you can make a comparison.

Post by: Shoduchi on May 16, 2018, 12:47:05 pm
The current revisions of the Passat hubs are 3C0407253F and 3C0407254F.

I bought a set of the cancelled revisions (3C0407257F and 3C0407258F), which I didn't know at the time because the ebay titles specified the current revisions. I have the Vagbremtechnic kit for the 4 pot Brembo calipers and 362 mm AP discs still in boxes waiting to be fitted.

just checked my ebay history and my left one has this partnumber :

there isn't partnumber in the ebay topic for the right one, but they were from the same car

I still haven't opened the Vagbremtechnic package. I suppose they fit since this kit has been used by many S3 and Cupra owners.

My calipers comes from a Porsche 986 Boxster 2,5L/2,7L  since the calipers from the Boxster S wont fit...  :signLOL:

And the S calipers are painted red from Porsche.. Mine were the dark blue/black' ish colour..

Mike from Vagbremtechnic has ordered some passat alloy hubs along with the wishbones and some calipers to check why my alignment of the adapters to the hub isn't fitting as it should.  :congrats: Hopefully a solution will come soon so that I can get to enjoy my brakes :)

If you check my build thread you can see that I fitted the TTRS 4 pot calipers with the 362 mm AP Racing 2-piece discs. That kit is listed for all the cars with the PQ35 chassis, I think.

Thanks. I can't see why that kit fits on a cast hub and doesn't on an alloy hub.  :thinking:

I hope Mike can get the bottom of this soon so you can get the new brakes fitted. :smiley:

So to close this - Mike is now able to make the right brackets to this setup.
The "old" adapters will not fit the calipers if you're running VW Passat B6, Audi S3 or Seat Cupra alloy wishbines with alloy hubs.

The new brackets will be able to buy by end of this month.
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Shoduchi on June 06, 2018, 10:57:45 am
So what's the difference between both hubs that made the brackets incompatible with the alloy hubs? Just curious... :thinking:
Title: Re: Passat alloy wishbones to mk5 hubs

How come the alloy wishbone won’t allow the brackets to fit...?
Bit of a strange one
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on June 06, 2018, 01:25:25 pm
Due to the thickness of the alloy hubs the brackets don't have the correct alignment and wont fit. The new brackets that now are in the progress of being made has a longer piece where the the calipers bolt to the bracket.

You can see the problem if you look at my pictures in ealier posts :)

It's not the wishbones that makes the problem.. It's the alloy hubs
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Shoduchi on June 06, 2018, 01:31:33 pm
The brackets bolt from the correct side. The thickness of the hub should only require longer bolts. I still can't see that the thickness would matter with them, just like it didn't with my brackets for the TTRS calipers. :thinking:

Have a look at this picture where the bracket is bolted to the hub and then see the bolt holes from the caliper to the bracket… This shows why it wont bolt on. Bolts holes from caliper to bracket are almost 10mm off

The brake disc is also bolted to the wheel bearing, so this is also sitting as it should
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Shoduchi on June 07, 2018, 09:48:06 am
I saw that picture but I still don't see how can other calipers bolt on alloy and cast hubs without any issue, while those brackets when fitted don't align well with those Brembo 4-pot calipers. :thinking:

I know that they didn't align properly. I'd like to see those brackets fitted in a cast hub to see where's the difference. :confused:
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on June 07, 2018, 01:45:11 pm
All right, thought you missed the pictures mate :)

Yeah still makes no sense to me at all either… However since Mike had the same problem with the hubs he bought along with these 986 calipers I guess maybe this hasn't been discovered before is that people that bought these adapters haven't had the alloy hubs installed.. And if they have the alloy hubs they haven't used these 986 brakes and went for something else - Just like yourself :)
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on June 08, 2018, 01:29:50 pm
This problem just keeps on giving  :signLOL:

Just heard from Mike today that the machine shop woun't recommend to extend the brackets the way so it'll fit. Mike also thinks it will sit to close to with the 312 discs so now we're starting to look into using larger disc to solve the problem..  He should have some disc ordered already and will have an answer if it's possible during next week.

Guess I'll just have to swap back to regular steel mk5 hubs  :sick: :sick:

What a weird problem!   The outboard side of the knuckle should be the same as the GTI hubs, otherwise the standard 312 brakes wouldn't line up either?

I don't get it!  :grin:

Give up mate, just stick the 340mm setup on there  :happy2:

Never! :D If a bigger disc can't sort out the problem then I'm going back to steel hubs :sick:   
Hopefully some other discs will sort it out though.. Really don't want to go back to steel hubs... All that work - finding some used ones, having the hubs blasted, powder coated, new screws'n nuts, new steering ball bearings and fitting of it

That explains the issue. The brackets are bolted on the wrong side to be compatible with alloy hubs. Just like the Brembo 18Z.  :wink:

Post by: colesey on June 09, 2018, 03:28:01 pm
It may be better to have VBT give you a refund on the brackets / discs and go down the 340mm route with either TTRS/DB9 or OEM calipers. Another forum member was planning on selling his 4 pot set as they wouldn't work with his Pescaras / suspension set up.

Yeah, I never done brakes before so actually didn't know that they did bolt on one way on the steel hubs and the other way on the alloy hubs..

Would be a solution sure, then I just need to strip those calipers - repaint and get myself some new rear brakes with 310mm discs.. Not looking at this option yet hehe.    They will weight to much for my everyday use and just look cool. ;)


More interested getting my current setup to work since this will save me alot of weight… Perhaps a better solution will be to go back to stock steel hubs if the alloy wishbones fits to the steel hubs? ..  :drinking:
Title: Re: Passat alloy wishbones to mk5 hubs

Only Porsche caliper brackets bolt on the inner side of the hub, that I know of. You can fit alloy wishbones with steel hubs.

Post by: colesey on June 09, 2018, 07:11:57 pm
I can understand how bbk / nqsbbk / CS brake options are tempting, however they all come with their own issues wrt cost / wheel clearance and increased unsprung weight. I found the link below interesting, figuring there is more untapped performance in the stock set up for road use, and now have all the parts ready to be fitted to my car next month

Any update on the ali hub brackets ?
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on July 05, 2018, 06:51:39 am
We're still trying out different solutions..
The problem is that to extend the adapter bracket to fit the alloy hubs it need to increase it's thickness to keep the same strenght. There isn't room for this ..

So bigger discs have been tried to move the calipers away from the center.. Didn't work out :thinking:

Now they are testing to see if they bracket can be made so the calipers sits abit higher in the current 312mm discs to make room for the needed thickness the brackets needs to be to before they are sure they will hold.

Steel brackets have also been tried but these wasn't strong anough either.


Hopefully within a week or so Mike should get back to me saying if they came up with a way to angle the calipers to make more room. If they don't it will not be possible to use 986 calipers to alloy hubs.. Atleast not with Vagbremtechnic adapters. :confused:

Wouldn't it be better to fit Clubsport S brakes? Similar cost and weight (with alloy hubs) to NQSBBK but no issues wrt fit / operation / wheel clearance and good enough for a 'Ring record.

For me those brakes are enough for 200 bhp for track use and 250-300 bhp for fast road use. With better discs (like the Clubsport S) and pads (PFC, Endless, Project Mu, Pagid RS, etc.) they can withstand more punishment before fading and overheating. :smiley:

The mk7 R/GTI PP calipers are just a larger version of the mk5 GTI OEM calipers (they're floating calipers). They will still overheat and fade more easily if pushed hard. With better brake discs, pads and brake fluid they can take more punishment than stock, but fixed calipers with 4 or more pistons are better for hard braking.
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: pudding on July 06, 2018, 05:51:23 pm
Agree with that  :happy2:  I run the PP calipers, GTI pads and Clubsport S discs, which in all honesty is overkill for my (now standard) engine but with my coilovers and these brakes, I can corner faster and brake much later - which is where the real fun is  :smiley:   You can get Clubsport S specific pads, which are twice the price of the GTI ones.  I reckon those with CS S discs can withstand track days OK.   

Obviously nothing will compete with proper 4 or 6 pot calipers for pedal consistency, but ultimately it is the disc and pad combination which determines fade resistance.  The biggest headache with 4/6 pots is packaging, which is why the Clubsport S setup is so good.  It's cheap, quiet, doesn't need spacers, doesn't need different wheels, custom hoses or adapters  :happy2:
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: JamesED30 on July 06, 2018, 06:23:57 pm
But still not as good as the NQSBBK 312mm kit with decent boxster s pads (modified) you would say??
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: pudding on July 06, 2018, 06:45:32 pm
Dunno, haven't tried them but on paper I would say not, imo. 

Why?  Because a 340 x 30mm disc has more leverage and heat dissipation capacity than a 312 x 25 disc, not to mention bigger pad surface area for more friction and heat transfer into the disc.   Calipers are only half the story.  The porsche calipers on the 340x30 disc, yeah, that would be a good mod, but on the 312 disc, I can't see the point personally, other than aesthetics, oh and weight reduction!
Title: Re: Passat alloy wishbones to mk5 hubs

Audi Q5 brakes is also 4 pot brembo and they bolts straight the mk5 hubs using 345 disc Incase anyone are looking for brake upgrade without all this hazzle hehe..

No word from Mike yet - will keep you posted in here
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on July 13, 2018, 06:27:19 pm
All right - as promised an update as soon Mike got back to me.
There’s no possible solutions left to solve the problem and none of the solutions were able to work properly and be save.

So conclusion is that if you have or want to drive with 312mm disc to Porsche 986 calipers you have to have the genuine mk5 steel hubs in order to make this setup work.

Is the Seat Leon Cupra running alloy wishbones and steel hubs standard or does this have alloy hubs also?

What weight saving is there solely in the wishbones?
Title: Re: Passat alloy wishbones to mk5 hubs
Post by: Christiank on July 13, 2018, 07:50:54 pm
Well the major weight saving in this setup is from caliper and discs.

I think alloy vs steel hubs as 1.8kg pr side or something like that. Total weight saving using wishbones, hubs and the 986 setup is over 18kg pr side.

Think there must be some mistake over the 18kg per side claim as Boxster calipers will save @3kg over the stock GTi ones.

Post by: colesey on July 14, 2018, 08:59:10 am
IIRC stock 312mm brakes are @15kg per side split roughly 50/50 between disc and caliper. NQSBBK will save @3.5kg per side and the alloy control arms @1.5kg, so @10kg total saving is available. That said, the guy with the stock brakes can also fit alloy hubs as well as the control arms, saving @7kg himself.

So the ali hubs are only 2kg lighter than the steels!?
I thought it was more. 😂
The complete assembly’s are pretty light. I’m just having mine blasted. But will be up for sale when I get them back.
