Not Ranked
I think you can go to a 12.88 +/- in the front and then a 11 or 12 in the rear. These will fit under 15" wheels. I ran this configuration on two Superformance cars with both sized wheels. The configuration was standard on the Superformance cars.
Iron rotors are just fine but finding the correct ones will take some searching depending on the other pieces you are using.
