This is a B9 A4 winter wheel from Europe. I just dont know what brake calipers they would have on the car that uses this.

I really like those wheels. Unfortunately have no clue if they will fit or not.

Thanks so much, you're a legend. From the pics seems like fitment was good, except for being off center from the rotor. Pads seem fine, or was it an issue?

Pads had a mm or 2 overhang on the 312mm rotors.

I will give it a shot on the 312mm rotors, and see how it goes.

Sounds good. Keep us posted.
Maybe 314x30mm rotors from VW Tiguan/ Skoda Kodiaq is worth a try? I found out on some russian forums that this A4 B9 ATE 4 pot swap is somewhat common there and they use this rotors (314x30mm), M10 banjo bolt (17-18mm length of the banjo bolt) to stock brake lines and they cut the harmonic dampers on the on the inner brake pad if using A4B9 pads, or they use pads from TTS for this swap (But TTS caliper has harmonic damper on the caliper, A4B9 has harmonic dampers on pads instead, so, mounting TTS pads on A4B9 caliper potencially can have NVH issues in my opinion)
OEM 314x30mm rotor part no. 5QF615301A/1K0615301AJ , Bosch part number 09.B635.11
Worth mentioning, that these calipers are produced in two versions, 318mm and 338mm. As they're monoblock, they must have fixed mounting points, making 318 version to small to swap on MQB
OEM part no. for left 338mm caliper: 8W0615107A / 8W0615107E / 8W0615107C / 8W0615107AA (factory painted in red)
OEM part no. for right 338mm caliper: 8W0615108A / 8W0615108E / 8W0615108C / 8W0615108AA (factory painted in red)
This calipers are found on A4/A5 B9, A6/A7 C8, Q5 FY,
Also worth mentioning, that Q5 FY, apart of 338mm ATE monoblock caliper, simultaneously is produced with 338mm Brembo monoblock caliper (the popular, Macan/Q5 8R brembo caliper is two-piece) and the rotor is the same for both calipers in Q5, so i think that it can be mounted the same way, on the 314x30mm rotor, like the ATE caliper in MQB cars.
Brembo monoblock calipers OE numers
left: 80A615107 / 80A615107A / 80A615107N (factory painted in red) / 80A615107P (factory painted in red)
right: 80A615108 / 80A615108A / 80A615108N (factory painted in red) / 80A615108P (factory painted in red)

It was such a fight getting these to fit. I had to use washers to get the brake pads to clear flush on the rotor. I have to do pads again soon and am hoping they fit. They are great brakes, though. Just a little sketch getting them to align properly on the knuckle
Maybe is worth a try to use the 314mm rotor from Tiguan I mentioned. I reread this thread and i saw that people mounting this setup with A4 B8 had issue with pad clearance as they were offset. I checked the difference between 320x30mm rotor from A4 B8 and 314x30mm from tiguan, and if Im doing math correctly, tiguan rotor should be 2,5mm closer to the center of the caliper (A4 B8 have around 52.1mm in height, tiguan 49,6mm)

Thanks for the heads up. Would you need to use the centering ring with the Tiguan one?
Not needed, because is from the car on the same, MQB platform. But to tell you with 100% confidence, I checked 312x25mm rotor centering from non-PP GTI and its the same, 65mm centering. A4B8 rotor has 68mm centering
