On the inside of my Door i have this

AB-BA-CB-DA I remember a post saying this is the code to see what size rotors and what size calipers the 9-3 SS has.

With that said this is what I'm pretty sure my car has

Front 16" 302mm Calipers 16" Vented
Back 15" 278mm Calipers 15" Solid

I was looking to get some EBC Brake Rotors for the front and back but I can't find any 278mm Rotors.

AutoZone / AdvanceAuto - all carry the 285mm rotors front and back.

I think I should be ok with the EBC Front rotors with a 302 mm vented but
when it comes to the back I only can find the 289 mm rotors and I'm not sure they will fit with my 15" calipers.

Anyways Thanks in advance.
