I need new front pads on my 2011 CTS performance edition. An online site sent me the wrong pads and they're too short . I figured I must not have gotten pads for the performance edition. I went to one of the larger part suppliers this morning and specified Performance brakes. I took the "new" pads to my car and compared them to the ones that were too short. They were the same. Took those back into the store and was told that's what's listed. Don't know what to tell you. Has anyone run into this or does anyone know what I'm doing incorrectly? I've been wrenching for 40+ years so I'm thinking it's not operator error. Thanks for any help you can offer.
