180sx brake question

[nisrix]

Hey guys, in the spring I plan on buying new rotors and pads for my 180. I've heard a few different things about which other nissan cars share the same sized rotors but want to be sure I'm getting the right parts, I'm pretty sure that the 240 has a different sized rotor. Does anyone know what rotors would fit my car that I would be able to get from any parts store over here? I'm not upgrading to anything serious I'm just planning on getting oem style rotors and a set of street performance pads.

Thanks.
