Right diameter, check the offset
My S4 B8 needed this doing at 112k miles. The hub face cleaned up first, then these went on with no shimming needed. The offset was not what the listing stated and it fouled the caliper carrier. That said, the steering wheel shimmy under braking from motorway speed has completely gone. Good part, minor niggles.

Straight, true and quiet
Bought for a 2011 Q7 4L. An independent specialist fitted them and commented on how clean the castings were. The vane casting is noticeably tidier than the budget set I pulled off. Result is stopping distance feels shorter and the pedal is firm rather than spongy. Good value against the dealer price.

Solid replacement discs
Cross-referenced the OE number against my 2005 A6 C6 before ordering. The hub face cleaned up first, then these went on with no shimming needed. Thickness came in bang on the OE figure when I measured it. Result is the steering wheel shimmy under braking from motorway speed has completely gone. Happy to recommend it.

Bedded in perfectly
My A4 B9 needed this doing at 159k miles. The vane casting is noticeably tidier than the budget set I pulled off. Needed a wind-back tool for the rear calipers but otherwise a straightforward job. Result is no squeal at all, even cold on a damp morning. Will be back for the other side.
