    Purpose of the Brake ducts is to direct airflow from the front of the car onto the Brake Disks so that if you are doing a lot of braking or track work it helps to keep the brakes at a better temp.

    I have just been told some of the smaller brake systems may have issues with fowling on the plastic but its easy to trim. Also my understanding is the Golf R and Cupra both support this with no issues and i have it on my big brake kit with no issues.

    Part Number

    These are fitted as standard on the Audi Range and cost about £30-00 to buy.

    There were no fitting instructions but its fairly easy to work out what to do and you don't need to be a mechanical wizard to do this.

    Firstly a couple simple picture to show the point of these ducts

    3.jpg
    The air flow to cool the brakes comes from the front of the car and comes through a small duct in the front

    But on the stock cars is not directed at the Brakes, The point of this simple bit of kit it to flow air directly at the brake disk's

    So what to do.

    1/ Doing the usual process Jack the Car up and take the wheels off.

    2/ Get the Plastic fitting ready to install

    As you can see in the below picture the brake duct will point towards the incoming air flow and re-direct it to the disk. This is the Drivers side being fitted.

    This simple item is help in place with 3 cable tie's .

    3/ Put you head over the disk's and you will see the following
    The area marked a D is in the way hence there being a cut out part that goes around it.

    4/ Now you have to fiddle around getting the Duct on to the wishbone mount

    As you can see in this picture along with the 3 cable ties you have three edges that go over the wishbone but only A actually clips in place the other two are just guides and keep the table ties taught.

    With the Duct upside down you can see all the clips that hold it in place.

    6.jpg

    So all you have to do is lay the plastic duct on the Wishbone you will hear a firm click when you push bit A down but the rest do not they are just there as guides.

    Once you have it in place and happy with it then using the cable ties just tighten it up as much as you can.

    Job Done.

    And here if the completed item from the rear

    Last point here is the blurb from the seller.
    If you have fitted the SuperPro Alloy Arms you will need to get a slightly different version.

    These air ducts are a quick and simple solution that fit to the wish bones via the supplied genuine cable ties to replicate how the 2018 Audi RS3 8V come from the factory.

    You will get everything you need included to fit the air ducts to your car. If you have the SuperPro Alloy Arms fitted then please select them on the drop down. They will come modified to fit the Alloy arms. No modification is needed to fit the standard steel arms

    Sorry just remembered another point.

    Make sure you have your doors unlocked when jacking the car up other wise the anti tilt alarm goes off which is a pain in the you know what.

    There are some comments that Golf Owners (with smaller brakes) have had rubbing issues but according to the web site these fit the LEON with no problems but as they are made of plastic its easy enough to make better.

    I fitted these today, only took (literally) a few minutes once the wheels were off thanks to your pics. I will try them at Oulton tomorrow :)

    Thanks and yes, it was awesome, I will probably pop a post up later. I stuck a new pump on in the end.

    On the topic of these brake ducts, they seem to make a difference. With 14 degrees outside temps and in partnership with my RSL29 pads, I gave the brakes some very hard sessions with not a hint of fade. Whoever at SEAT decided not to fit them as standard deserves a poke in the ribs :)

    Afraid along with all the OBD11 Stuff you can do its down to VAG trying to hide the fact we have the same car underneath.

    Lucky for us you can fit the parts aftermarket much cheaper than they cost on a Audi new :)

    By the looks of it these brake ducts for the 8v RS3 are quite a new thing even for the Audis (unless I am reading it wrong). Seems people were still looking for solutions just last year. Some interesting before and after brake ducts being installed thermal pictures on an RS3 (albeit not the factory ones): https://www.audi-sport.net/xf/threads/solution-for-rs3-brake-problems.339975/

    Well they finally got round to it and managed to sort it, although still makes me laugh that its tied on with cable ties, I always thought Audi were up market :).

    Anyway the important point is they do seem to work.
