Pretty good so far!

Would like your opinions on the news sources in the UK, which ones are reliable? Which ones to avoid that post alot of fake news?

Hello all! After living with this upgrade for a few days, I have some more notes / thoughts on this upgrade that I am happy to share with you all, in case any of you are looking at doing this upgrade for yourselves.
I am happy to answer any questions you have in the comments. (Went from 312mm disks to 345s)

So I have bedded in these brakes using the mintex racing procedure for these pads and I have to say, this definitely felt like a solid upgrade. At first, the pedal will feel spongy and inconsistent as you brake for the first few times. Do not worry! The pads take a little time to align up better with the disks.

I have noticed that ABS barely kicks in anymore, this makes sense as theres more fluid being pushed in the caliper. I havent managed to hit ABS yet, the wheels just stop faster, no tyre squeal, nothing, it feels far more solid than the prior 312mm disks and the braking distance has shortened by quite a bit. These calipers feel like they use up almost all of the performance out of the brake booster.

After they have bedded in, when doing medium to hard braking there is a very subtle vibration and whooshing noise. This is from the slotted rotors scraping away at the pads and cleaning them, as well as air getting between the C hooks and the pads.

Your brake bias will move forwards, so you may feel it become a tiny bit squirrely on the rear, but as long as you keep your steering wheel straight, you will be fine.

Pedal travel -> someone correct me if i am wrong, the biting point of the brake is about 20-30% down the pedal, not at the very top of the pedal like other cars (e.g skoda octavia), I cant tell if this is normal or worse than before, MK3 owners let me know if its the same for you? I may just need a quick re-bleed after bedding them in.

The RS3 brake ducts will fit almost perfectly on your lower control arms. I paired this with the Golf R dust shields behind the disk, and pulled back part of the dust shield that was blocking air flow. Its a small triangular tab but should work fine.

For disks I want with VBT 345mm slotted disks and for pads I went with Mintex racing Mrm1801 pads.
I no longer have need for my old calipers, so if someone would like them, feel free to reach out!

Hi all! Managed to complete my brake upgrades for my mark 3 TT! I have some notes and thoughts to share.

I felt that the standard disks and calipers were far too small to take on track and suffered from brake fade, so I upgraded from 312mm disks to 345mm disks and porsche macan calipers.

You dont need spacers on the 19 inch alloys, suprisingly, you can get away with 5mm of clearance which is more than enough.

Yes these calipers are a direct bolt on option and I will link all the parts I bought below. (I bought the dirtshields separately and didnt think they would fit but they worked!) (340mm golf dirtshields)

The braided lines that come with the calipers fit perfectly. You will need to cut the pad wear sensor off your old pads and bridge the connection so you dont get any errors on the dash. You can tuck these away.

Here are the list of all the parts I got and all you will need if you decide to do this upgrade on your own Audi.

Dirt shields / dust shields

Can anyone guess what it is? 👀

An actual targeted strike wtf.

So! I am upgrading my calipers and I am going from 312mm disks to 345mm disks, but I am struggling to find the right dirtshields to use. Apparently you guys might have figured it out for the golf MK7 platform? Advice appreciated!
