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

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:

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 :)

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

Here's a picture of the brackets mounted on the standard steel mk5 hub

Interesting!  The bolt goes in from the opposite side on the GTI hubs?

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

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:

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

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
