Wrong offset for my car
My Q3 8U needed this doing at 87k miles. The offset was not what the listing stated and it fouled the caliper carrier. Expected better given the cost.

Never stopped squealing
Ordered this for my TT 8J after the original gave up at 59k. They never fully stopped squealing no matter how carefully I bedded them. Swapped them on the driveway with basic tools in about two hours a side. Would not order the same one again.

Bedded in perfectly
Replacement for my 2013 A8 D4 3.0 TDI V6. Runout measured well within spec on the dial gauge. Took my time bedding them in over 200 miles as the instructions ask. Result is the steering wheel shimmy under braking from motorway speed has completely gone. Would order again without hesitation.

Exactly the right spec
Bought for a 2015 S3 8V. Swapped them on the driveway with basic tools in about two hours a side. Runout measured well within spec on the dial gauge. Result is eight months and several thousand miles later they are still dead smooth. Happy to recommend it.

Pedal feel transformed
Bought for a 2017 A3 8V. 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 no squeal at all, even cold on a damp morning. Good value against the dealer price.
