i don't know much about the 33 brakes, i would assume on the non Vspecs it would be the same 296mm. x 32mm as the R32's...

either way, it's not about my lame ass OEM rotors, it's about the brake pads... i've had drilled rotors before, with EBC Green stuff pads for example, and they never never made a peep...

although like the above link at my350Z, it seems as is the noise is quite common with the HPS pads...
