Does anyone know whether the brakes on a non-sport package 2004 A4 3.0 Quattro Cabriolet are any larger or different at all from a regular B6 1.8T sedan?

Thank you so much.

Weird that the caliper is the same, but the rotor is larger.

They just use a larger caliper carrier, that you can buy if you want to go with larger rotors.
