Wow! It's like driving into a big marshmallow! Fast, smooth stops, no drama. I had a bad rotor and decided to just buy new better stuff instead of throwing away the old rotors etc. They are very cheap, look good, fit perfectly and last like I can't believe. A limitation; Hacking is very specific and very important. You should do it almost as the instructions say to get smooth and quick stops. I've had bad experiences with aftermarket brake products but not with these, they are very clear on how to install and break in them. And best of all, they work great!
