One of the best purchases I've ever made, my car now stops at a dime. I work in the mountains and the stock brakes get very, very hot on the bottom even when using a low gear causing the stock brakes to lose tons of braking. Now I can go down as fast as I want, the brakes get a little warm, but they don't go away at all, even though I've installed slotted brake discs. Total confidence in the performance of these brakes.
