    So have you got the above brakes fitted to a standard T3?
    Can you tell me the caliper fixing location measurements so I can check on my Syncro
    Do you have a list of part numbers to suit?

    not yet Peter I hope to have them sorted in the next few weeks. The brackets are being made at the moment and I am rebuilding the calipers right now (I know its 9PM) hubs are being machined next week, just the flexible lines I am not 100% on yet.
    the caliper mounting face to face of the hub on the 2wd measures 87.9mm. The center to center distance of the mounting holes is 89mm and the total size of the hub to fit the Audi disc over is 133mm.

    I still need the small car version as I only have 15" alloy wheels on my syncro.

    Love the look of your kit though Nils...

    the ATE calipers from the Audi are the same whether you use the 312 or 288 rotor, it's just a case of finding the correct carrier.
    I'll see what I can dig up.

    Hi Have the Tiguan 16" Alloys. Interested in the outcome of this thread.
    From what I have read the SA Big Break kit is underwhelming.
    It would be good to have a hunting list of Audi parts for bigger breaks.
    Would you be able to make us up such a report nils?
    Sounds like you are on the right track

    Since starting this thread I have been doing some research on the subject

    A common upgrade found on the net uses Audi calipers and rotors.
    One of these uses the G60 Girling Caliper found on Audi's from mid 80's to early 90's. These are a two piston caliper.
    Some of these G60 units are still to be found here in Oz.
    The rotors (disc) used in this conversion are 276mm dia x 25mm with 5x holes. These discs seem to be hard to locate here in Oz?
    Anyone know a good disc outlet?
    This upgrade is fairly straight forward.
    I am also checking two other upgrade options, not Van-cafe or SmallCar options.

    hi Peter,
    go onto the brembo aftermarket site. You can search rotors by size, then locate part numbers and what car they came from. Using those number you can usually google a stockiest of what you require.
    There is the possibility that the size you are looking for is a modified disc. I do remember a lot of threads on the samba looking for a replacement disc for a big name conversion, it was concluded that the seller was modifying discs so that replacements could only be had though the same source.

    Oh by the way, your hat hieght is the most important piece of information.

    Yo Nils
    Yeah - been to the Brembo Web site - was a bit disappointed- thought they may have had more on Calipers - as you said, its a good site for rotor sizes.
    Another site I have found useful is SparesBox.com.au
    Its a local site and has a useful search engine for parts
    Think I'll use the 288 x 25 mm rotor like in the link below - if its too large in diameter, have it turned down to suit.
    There are cheaper examples list on the same site.
    Price is for a pair
    https://www.sparesbox.com.au/brake-rotor-pair-textar-92057603-39-92057603

    The 46.2mm is the Hat height you refer to ? (as seen in the above link drawing)

    Rang the Stopmaster Brake people in GatesHead today... Thanks for the tip
    They can supply a service kit for the dual caliper G60 Girling caliper - for a whole $35 big ones.. ! (per unit)
    Big difference from $135 a kit down to $35...!
    So this makes the G60 option reasonably affordable,
    Second-hand G60 calipers at $110 each = $220 plus post = $250
    Service kit x2 = $70, post $75
    Rotors allow $180 pair - post= $200 (288 x 25mm)
    Machine the G60 calipers - allow $100
    Brake pads $ 60
    Bolts & miscellaneous $25
    Totals $710 complete
    some brake fluid, etc

    Pretty sure the guy doing the rear disc brake kit has upgraded his fronts to Audi discs and no adapter plate required. I have no other details but once his identity is revealed perhaps anyone interested could have that conversation with him.
