Put Wagner rotors and Thermoquiet semi-metallic pads on the 94 ZJ at about 180K miles. Before this, every set of brakes gave me problems, the rotors would ALWAYS be warped within 5k miles. The Wagners are still going strong. The pads are still about 60% left, and I drive pretty hard. They have been very quiet since day 1; most people have noise problems with the Wagners because they do not burnish the friction after install. If you do burnish them, you'll have much better luck. I only get a little chirp when I first drive after a rain storm. Definitely spend the extra $$$ and choose the Wagners over the other parts store "in-house" brands.
