here is what you do, you go to advance auto parts, autozone, etc... and order loaded calipers for a 99-00 Mazda Protege ES 1.8. Then you buy the rotors of your choice for the 99-00 ES 1.8 and if u want a bit more stopping power get some nice hawk hps pads. This will give u the greatest benefit in braking for your money spent. Just using drilled rotors on the 99-00 1.6 protege is a joke and wont give you any braking performance gains.
