They immediately stopped the squeak my 2014 Challenger with Brembo pads was having. I can't tell much of a difference in braking performance compared to my Brembo so it's definitely worth upgrading. If you have slotted rotors you will find it difficult to break the spacers to transfer material from the spacer to the rotor. Slotted rotors run cooler than standard rotors. YouTube has a tutorial on how to properly lap slotted rotor pads if you need even better braking performance. I am very satisfied with the excellent price and excellent quality.
