Better than the dealer discs
Went on my Q7 4L 2.0 TDI at 62k miles. Runout measured well within spec on the dial gauge. An independent specialist fitted them and commented on how clean the castings were. Result is stopping distance feels shorter and the pedal is firm rather than spongy. Will be back for the other side.

Bedded in perfectly
Bought for a 2015 S4 B8. Needed a wind-back tool for the rear calipers but otherwise a straightforward job. 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.

Fine once bedded, noisy first week
Replacement for my 2006 A6 C6 3.0 TDI V6. An independent specialist fitted them and commented on how clean the castings were. Machining on the friction face is even all the way round. On balance eight months and several thousand miles later they are still dead smooth. Fine for the money, with that one caveat.

Exactly the right spec
Cross-referenced the OE number against my 2012 A4 B8.5 before ordering. An independent specialist fitted them and commented on how clean the castings were. The protective coating on the hat means no unsightly rust ring after a wash. Result is no squeal at all, even cold on a damp morning. Will be back for the other side.

Solid replacement discs
Bought for a 2014 S3 8V. 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.

No more steering shudder
My A4 B7 needed this doing at 127k miles. An independent specialist fitted them and commented on how clean the castings were. Runout measured well within spec on the dial gauge. Result is the steering wheel shimmy under braking from motorway speed has completely gone. No complaints at all.

Straight, true and quiet
My A6 C6 needed this doing at 155k miles. Needed a wind-back tool for the rear calipers but otherwise a straightforward job. 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. Cannot fault it.
