Review on K4448 Evolution Drilled Slotted Ceramic by Robert Howell

I've changed the brakes on my KIA about 3 times and they've all failed in a relatively short period of time. I wanted to try them to see the difference and I can say without a doubt that they are the best brakes I have ever used. Braking performance and smoothness are a clear improvement. Time will tell if they last longer but I am very happy with this purchase. Bearing rotors bought at local auto parts stores are cheap, but that's about all there is to say about them. They all seem to deform within 10,000 miles.
