Well, unfortunately, I can't afford to own nice cars like Audi S4, so I have to resort to upgrading minor parts like brake disc and pads, and I even have to do it on my own to save some money. Anyway, my N16 is not a high performance car in anyway, in relatively stock form (unless you consider K&N air filter, light weight rim, suspension upgrades modifications). That doesn't stop me from making my daily driver a better car. Instead of making the car going faster, why not make it stop better? There's almost no choice for any better performance brake pads for my car, and I had to buy from US! And the shipping costs as much as the pad itself! Hawk Performance HPS stands for High Performance Street, perfect for my usage since I don't go track days. The exact model for my car is HB598 F.606. It comes with some grease, and a horsepower boosting sticker. I also bought a set of new Brembo blank disc rotors. It is highly recommended to replace the rotors with the pads together since the worn rotors are not flat anymore. Some of the additional tools that I got to upgrade the brakes, jack stand, G clamp.
