Save me the return shipping charges. Rear Brake rotors for a 2007 Mazda 3 with a 2.3ltr engine or S trim type. I ordered the wrong ones for my car. Registration said S series but I have an I series 2.0ltr. $80 for the set. Fits other years. Let me know what year your Mazda you have i will check for fit. Sending them back Oct 12th.
