I saw where another GTO owner found out that the Corvette C5 front brake pads fit the GTO without any modification. I've only had my car for a week so I just slipped the Vette pads in since the rotors had no noticable wear. It only took me 30 minutes for all aspects of the change. I could not believe how small the stock GTO pads were compared to the Vette replacements. I believe it will make a significant difference. I used Raybestos part numer is PGD731QS. These are the new ceramic low dust pads. Since the Vette's rotors are 4 mm thicker than the GTOs, I plan to not let the pads go down to nothing and avoid over-extending the brake pucks. Here's the link I used to if you want more details.
