I've done quite a few brake jobs and never come across this, but what are performance brake linings? I'm most likely going to go with OEM Delco pads, and they have two options, one with, and one without, these brake linings. All I could find on this was some conflicting opinions on whether or not they create more dust. I have a 2015 base ATS, so I would venture to guess that I do not have these linings because this was not something I recall paying for almost four years ago. Thanks in advance.
