Nice upgrade for the flimsy rims that came with the car. Too bad the pads had a lot of life left after 50,000 miles - looks like they could go 30,000 miles or more. But with each long ride, the front rotors heated up and began to pulsate. Too bad the Top Cop pads don't come with rotors as a set - if you want one you have to buy it and then buy the pads individually, effectively wasting a set of z23 pads. Spring. Still better than OEM. Nice that you took the step.
