Hey all!

Looking at upgrading my 2019 Octavia RS front brakes, but wanting to do it using OEM MQB parts as I don't feel like spending over £3000 on a big brake aftermarket kit.

What vehicles can I swap front (and even rear?) brakes from? I want something around 356mm or the largest I can get inside 18" or 19" rims, and what other supporting parts would I need to make this happen such as carriers etc?

From what I understand and have gathered so far, I can use brakes from:

Audi TT RS 8J (+ Carriers) (min. rim size ?)
Audi S/RS3 8V (+ Carriers) (Min. rim size 18)
MK7/7.5(?) Golf R (+ Carriers) (Min rim size 18)
2017 Porsche Macan (+ Carriers) (Min. rim size ?)

Is my info correct, am I missing any other cars? Help and advice appreciated!

I'd also like to get a list of all the compatible parts, put them into a nice table (sexy excel spreadsheet!) and have it shared for everyone, so anyone can instantly see OEM alternatives that would display MQB compatible swaps, extra parts required, brake disc sizes (I'm aware some cars came with multiple brake sizes, such as some S/RS3's and TT's), minimum rim sizes required, and any other information required that would be relevant.

Basically, the other half has a Mini JCW with absolutely ginormous brakes. Parked next to my Octy, it makes the brakes look anaemic and I'm not having that! Lol. Brakes are also due for replacement soon as they haven't really got much meat left in them, so would like to buy an upgrade now, rather than buying new discs and pads, and essentially burning that money by upgrading.

Cheers in advance guys!

If you want to do it absolutely right, or if it actually has to be done anyway, you have to code the ABS to the new Brake If The firmewre have the New Break in the rirnewre

I did a parts list for the TT RS upgrade years ago. Not sure if it’s still accurate but it’s a start if you want to explore it:

Caliper Left  # 8J0615107B

Caliper Right  # 8J0615108B

2 X Rotor  # 8J0615301K (370mm)

Pads  # 8J0-698-151-K 

Sensor  # 8J0-615-437

2 X Caliper carriers  8P0615301

Splash shields 8J0615311E (may need modifying)

Good luck.

Mate, you absolute legend!

Thanks for the advice, what do you mean by (May need modifying)? They need cutting in places or is it a case of re-drilling certain holes? Out of curiosity, do you know the model year/chassis designation they come from?

What size wheels do you roll with those? At current, I have 18" and would prefer to keep them for the added comfort of the extra tire profile, but if needs be, would look at swapping them out.

In terms of the splash shields, I never ended up doing them myself. I can’t remember why I wrote that there but vaguely remember one corner may need cutting off.

My understanding on the rim size requirement is that the TTRS calipers+370mm rotors will fit under any 19, but require specific 18s or the addition of a wheel spacer to fit. Best to do some google research to see what you can uncover there.
