Installed a diy brake retrofit on the Q3.
I haven’t found a thread where someone who documented this retrofit on a MKI Q3 Quattro. I am going to try this and share about it here.
DISCLAIMER
If you choose to do this, it is at your own risk. I cannot and will not accept any responsibility if you choose to try this retrofit.
I will keep updating this thread as I encounter problems and attempt to sort them out. I will also edit this first post to show the most updated information.
The thread I followed was for the PQ35 VW Golf. It shares the same chassis as the 2015-2018 Audi Q3/VW Tiguan.
The retrofit calls for:
2007-2010 VW Touareg Base 4 piston brake calipers (BM5) and brake pads.
(BM5 supposed to be the same as the 1LE), it says in the thread that the 17z will work as well. I can’t verify the 17z or the 1LE, as I am installing the BM5.
2008 Mercedes ML320 Base Diesel 330x32mm rotors.
The only thing with these rotors is the center bore is larger than the hub and a special hub ring adapter must be used. Also the mounting screw hole on the Mercedes brake rotor does not line up with the Q3 hub.
Hub centric ring adapters
They come in plastic or metal. I ended up using the 65.1/67.1mm plastic ones. The metal ones did not work for my wheels and spacers.
I initially gave out bad information
CORRECT IS 65.1-67.1
NOT CORRECT 57.1-67.1. My abject apologies for that.
MKIV R32 Brake hoses
Required for the the Brembo Caliper when used on a Q3/Tiguan.
Wheel Spacers with matched lug bolts.
Required for your front wheels to fit around the larger brake caliper. A minimum of 10 mm was suggested, however I used 12mm ones.
(Not required but will look strange without)
If you don’t get rear spacers it will have a strange stance. I ended up installing H&R 20mm spacers with matching lug bolts on the rear wheels.

I made many mistakes and shared it here.
Wheel spoke clearance bothered me.
Caliper and rotor.
