Fine at first, pulsing later
Went on my TT 8J 2.5 TFSI at 110k miles. Needed a wind-back tool for the rear calipers but otherwise a straightforward job. They developed a pulsing through the pedal well before they should have. That said, no vibration through the pedal even on a long downhill run. Fine for the money, with that one caveat.

Solid replacement discs
Replacement for my 2010 A4 B8 2.0 TFSI. Carrier bolts came off without a fight and the new discs dropped straight on. The vane casting is noticeably tidier than the budget set I pulled off. Result is no vibration through the pedal even on a long downhill run. Would order again without hesitation.

Better than the dealer discs
Went on my Q8 4M 3.0 TFSI V6 at 149k miles. An independent specialist fitted them and commented on how clean the castings were. Weight and vane count match the originals exactly. Result is the steering wheel shimmy under braking from motorway speed has completely gone. No complaints at all.

No more steering shudder
Second one of these I have bought, this time for the A6 C6. Thickness came in bang on the OE figure when I measured it. Took my time bedding them in over 200 miles as the instructions ask. Result is no vibration through the pedal even on a long downhill run. Happy to recommend it.

Warped inside 3000 miles
Second one of these I have bought, this time for the Q8 4M. They developed a pulsing through the pedal well before they should have. Would not order the same one again.
