That depends if the rotors are direct replacement. If they are then, no. But if you need to ask, you should seek professional help. Cross drilled rotors are a bad idea on a street driven car as you loose contact area with the pad. Don't do this to your car. It wouldn't come close to the performance required to make drilled and/or slotted rotors useful for you. There is no way your gassing the pads on an A5 unless you drive like a idiotic crazy person. Please drive safe as you share the road with everyone.
