I installed the Z23 front pads last week and was so impressed that I decided to buy the Z23 rear pads as well. I have a new Nissan Murono and was having trouble stopping. It always felt like I had to press the brake pedal really hard to get it to a quick stop, especially at higher speeds. Maybe the original pods were defective, peanut butter pods or something. But I installed Z23 pads and now it takes almost no effort to stop. I recommend these pads.
