Pedal feel transformed
Fitted to my 2007 Q7 4L. 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 the steering wheel shimmy under braking from motorway speed has completely gone. Cannot fault it.

Works, but check your part number
Cross-referenced the OE number against my 2012 Q3 8U before ordering. 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. On balance eight months and several thousand miles later they are still dead smooth. Fine for the money, with that one caveat.

Solid replacement discs
Fitted to my 2008 A4 B8. Machining on the friction face is even all the way round. Took my time bedding them in over 200 miles as the instructions ask. Result is braking is quiet and progressive where before it grabbed.
