WJust some camparison of the Z06 and Brembo rotors
Here's the diameter difference
And here is the height difference. Its about 1.5". Square is resting on top of Brembo rotor hat surface. This is one reason I went to the Z06 rotors. The Brembo is a taller rotor and so pushed out the Z06 wheel further past the fender line. I did a quick test fit and the Z06 wheel will be nearly flush with the fender.
