You can use pads from any other brands, as we use the same design as AP racing. We can send you the references of the pads in order for you to check. Just let us know.
Almost all our customers come back to get our spare pads, because the price is affordable and the compound is specially developed for our rotors. They give day and night performance, endurance and bite, compared to stock brakes with sports pads, so people don't usually try to improve braking and bite further than what our sport compound offers, for street and even proper track use. The race pads are for race use only, as they need to heat up to perform unlike sport and street pads. Please keep in mind that even our street pads are used by some of our customers who drive on tracks.
