The stock Honda/Nissin brake pads are PhP3000 or so for a set of 4 to be mounted on the front wheels, if you buy from the dealership.
I would recommend Bendix's pads. Their General CT and Ceramic lines are the cheapest and should cost under PhP1200.
For harder braking, the Metal King series is PhP1600, and the Ultimate series is around PhP2500. These are already good for competitive driving and race use. HTH
i went to speedyfix last saturday to have it changed. They used bendix, it cost me 2000 pesos including the labor and the cleaning of the rear break pads.
It was my first type in speedyfix, they really are speedy. hehe
