I decided to try a new product for my performance cars brake system and couldn't be happier with the results .Automotive safety is important to me AND thanks to my knowledge gained in practice, I knew that copper-free brake pads were the way to go. These Premium Copper Free brake pads offered superior stopping power and reduced brake dust, which was a huge plus. The only minor con was that they initially had a bit of noise but it subsided after a few hundred miles. Overall, highly recommend!
