Pads & Rotors - world compatible?

[SURTEESS]

I have just had my car serviced (pick-up later today) & the guys reckon that in approx 3 months the pads will be down to minimum, they also mentioned that the rotors are pretty thin also.

So I was wanting to "upgrade" both front & rear to drilled & slotted rotors together with ceramic pads.

But my question is are these parts the same around the world?

I will find out the part numbers from New Zealand.

Does anyone know if Dayle still works at www.Motorsportwarehouse.com as I am keen to buy from them (as I have bought stuff from them before).

thanks

Stephen.
