I recently purchased a new set of brake pads for my performance automotive and after doing a lot of research I decided to go with this product .My analysis of this product showed that it is made with premium copper free materials with a CFM763 rating, which guarantees excellent performance during high-speed driving. The installation process was also a breeze and it has greatly improved the braking system's overall performance. Though it is a bit more expensive than other options, the superior quality is worth it..
