Brake System Configuration

[Jim Vander Wal]

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.

Are you sure about the 12.88" size in the front? We use a similar 15" wheel in the front and our maximum is a 12.18" diameter rotor.

I can't confirm. Car is long gone. Yes, my memory could be (is) fading.
Sorry if I've presented bad info.
But, I think I have a set of Superformance rotors hiding in the storage racks, I'll check and respond.
