This DFC Brake Kit - QuickStop Rotors with 5000 Brake Pads kit is jam-packed with features to give you the ultimate stopping power. For example, DFC's Quickstop rotors are made from high G3000/G11H18 iron castings for optimal strength, stability, and endurance. They're also designed to match the OE vane configuration for less brake wear and better cooling, and they're quality-tested to assure superior stopping power. DFC's Brake Pads, on the other hand, are produced with a premium ceramic composition that provides exceptional fade resistance and consistent friction performance throughout a wide range of temperatures. You can expect nothing but the optimum stopping performance from your car when these two brake components are combined in one kit.
