Having read the reports about brake wear on European cars I would like to tell you my experience with my VY Commodore. Replacing the discs and pads with PBR slotted discs and matched pads has improved the braking performance considerably, so maybe these people should do likewise.
Consulting a brake specialist, like Howard Reynolds at Race Brakes, is always worth doing. Car makers fit components to meet certain performance criteria, like stopping distance, fade resistance, and longevity, and it's possible to improve on some aspects by going to other, or better discs and pads.
