I have installed 2 of the Power Stop kits on family cars. My daughter absolutely destroys every car she drives and the brakes are usually the first to go unless she kills the engine or transmission first. I used a Z23 kit without calipers on her 2009 Impala. They worked really well. Improved stopping power, smooth and quiet. No pulsation until she totaled that one after about 15,000 miles. Generally, she would have the front's pulsating after a brake job in 5-7K miles. The second kit I installed was on a 2008 Hemi Grand Cherokee for her. This was a complete kit with 4 calipers. Very nice stuff and so far after a year and a half and 20K+ miles, the brakes are still really good.
