My wife "warped" the hell out of the Z rotors in <20K miles. With poor braking habits. It took an Accord 6MT (30K miles), the Z 6MT (20K miles), and an Acura ILX AT lease (45K miles) to "brake" her of those bad habits. She's got 25K miles on a new Accord Sport AT with no issues yet :crossfingers:
I took over daily driving the Z at 21K miles, immediately replaced the pads and rotors and 70K miles later absolutely zero issues with shuddering or excess pad deposits
