skyline over z32 conversion for 240

Just discovered you could throw on skyline parts rather than z32 for conversion to 5 lug and bigger brakes. Are there any suspension benefits from this over the z32? Im really wanting it for bigger brakes, though Im not sure whether or not brembo makes bigger rotors for skyline. Im hoping they make a 14 inch, but havnt had any verification. Ive already checked the brembo site and the overboost store and couldnt find the size, but I figured I'd ask you guys first before searching further. Anyone done this or know someone who has?
