I need to replace rotors on a all four corners of my 9-3 Aero (2004) but I can't seem to find anybody who can tell me what sizes are the rotors on my car. Some tell me Canadian Aero off that year come with 314 mm (12,4 inches) at the front if you have 17" wheels (like I do) and 292 mm at the rear. I took off a front wheel and tried measuring the front rotor without removing it and it seems that they are not that big. Seems like they are around 304 mm. The Saab dealer in my town tells me they are indeed 314 mm and he's asking $590.00 CAD (!!!) just for the front rotors. Anybody can help me on this before I order some Brembos onlline with a set off good pads ?
