I bought these for my 2007 Nissan Armada and hooked up the setup to stainless steel brake lines. Truck weighing 5600 pounds now holds up like a small car! It's hard to say how much of the power is due to the brakes, but they haven't distorted on me and are taking a long time to fade. The reason for four stars is that they make a clicking sound when you use them (think wheel of fortune). ). This is very annoying, but is mostly noticeable with the windows down (I love the fresh air). The backs also changed color to yellow when I put them on, but this did not affect performance. They hold up well to the elements, but after 7 months and 7000 miles the outer perimeter started to show signs of rust (hats hold up well). We'll see how they hold up in the snow and salt, but overall they were a steal. The pads are not dust-free, but do not adhere very well to the rims for several weeks. I still have a lot of life on them. Another annoyance is that the Amazon rotors are not packaged separately and may become damaged. I had to send another set.
