This installation hardware is a fantastic upgrade for any automotive enthusiast looking for better brake performance. My analysis of this product showed that it fit perfectly to my brake system, making it easy to install... The semi-metallic formula provided a noticeably improved stopping power that gave me confidence on the road. The only downside is that they can produce more brake dust than other types of brake pads, but this is a common trade-off for better performance. i highly recommend this product..
