This is a great upgrade for the Audi Q7. Little dust, hard braking. I think I read somewhere that perforations/notches weren't necessary, but after the original rotors warped I felt that better air/heat dissipation needed to be done. So far they are great and worth the extra money. Be sure to follow the break-in procedure outlined in the seal instructions (located on the packaging). This came with all 4 pad sensors (but results may vary or so it seems). Make sure you have a 16mm XZN/Triple Square for the rear brake. Also a proper front brake socket would be nice to use to remove the brake line bracket.
