The pads appear to be well made. Stopping power is better than the originals on the car, and, best of all, they don't leave the horrendous, sticky brake dust common to German made brake pads. I now have the only Audi around that always has shiny front wheels! Can't really comment on installation because I had that done at my local shop. Have to see how durable they are, presently have 2,500 mile on them.
