What size are the stock rotors?
 

I've searched and turned up nothing. how big are the stockers?

Is your 8 automatic or manual? According to mazda's website, the automatic has 11.9 in. rotors all around, while the manual has 12.7 in. rotors up front and 11.9 in. rotors in the back.

brochure says 12.7 inches for GT pkg. and i'm not sure which are equipped with 11.9 inchers... maybe sport only? or even touring as well???

but GT goes 12.7f/11.9r and sport 11.9/11.9 iirc.

don't quote me on it tho.

I have an auto, but it has leather. I think I read somewhere that all leather cars are GT's, right? I bought it used, so I'm not exactly sure. The fronts are bigger than the rears, so does that sound like the GT package with the 12.7's in the front? The car came with the stock 18's...if that has anything to do with it.

the SEARCH YOU LAZY BASTAGE size

The sport suspension (18 in wheels) has the larger 12.7 in the front. Doesn't matter if it's an auto or not.
