These brake pads are a legitimate improvement over the stock brake pads on my 2012 Mustang GT. I'd say the improvement is an easy 5-7 feet shorter from 60-0 MPH. However, they are somewhat dusty. I don't think the pads are unbearably dusty nor do I care as much as some people. I clean my car weekly, so it's a small issue to me. I value performance, and these pads deliver.
