XF series Xcarbon ceramic brake pads were developed with characteristics that make them perfect for most demanding brake applications. Ideally formulated for faster stops, heavy duty pay loads, and high heat conditions including light track use, the XF series pads can be used on sports cars, SUV’s and trucks that demand increased stopping power. They provide a consistent coefficient of friction (0.50) at any temperature, providing very predictable braking and great pedal modulation. Combined with ultra-low wheel dusting, and excellent noise abatement characteristics. If you are the type of driver who demands track-day braking performance out of a pad optimized for the street, then the XF series Xcarbon ceramic brake pads are exactly what you need!
