WP Pro offers replacement brake pads for their big brake kits. These brake pads are high quality carbon metallic in their street (gray) compound. These are sold as an axle set which is 4pcs for the rear S4 caliper. Information:
WP Pro has developed this great brake pad compound for it's calipers. Choosing a brake pad is very important to your driving type and usage. For most Big Brake Kits that are used on the street, these kits come with the Grey Type (Street/Sport) brake pad. This pad is fitting for the street car where it does not require any warming up of the compound working from 0-500 degrees Celsius. For those looking to take advantage of the full engineering of a WP Pro brake kit on the track, we recommend the Red Type (Sport/Track Day) brake pad instead. These pads need to be warmed up and go the distance from 50-600 degrees Celsius.
WP Pro Brakes has been in business since 1981 with facilities in Canada, Taiwan, and the UK producing high quality OEM and aftermarket braking systems. It does everything from forging, machining, assembly, and even race car testing. This is not just another colored chinese caliper kit, there is engineering behind the WP Pro components. Proving this point is their Race/Track brake systems. The specific calipers share the same body as their beautiful EX6 6piston caliper but with titanium vented pistons, 3D machining on the body, for where looks are secondary, and performance is the main focus. The 6-piston race caliper weighs just 2.6kg and is designed strictly for racing. These WP Pro racing kits were developed for the WTCC and Asia Carrera Cup racing series. Having partnered with the Chevrolet Cruze WTCC teams, their 4 piston calipers are the same design as the EX6 and include anti-knock-back springs, titanium piston covers with stainless steel pistons, and a structural bridge. These calipers were tested against some major companies' calipers and proved stronger and more rigid.
What we are really excited about is its Carbon Ceramic rotor offerings. For years it has been only the OEMs who had the carbon ceramic rotors as a factory options. This option could cost upwards of $30,000 and good luck finding cheap or any replacement parts. The reason carbon ceramic rotors are so highly desired is they are EXTREMELY lightweight and simply do not fade. WP Pro Brakes has a huge application list of Carbon Ceramic rotors for almost every high performance car including Aston Martin, Ferrari, Nissan GT-R, Porsche 996 997 Turbo or GT3, and others. Of course these are not or never will be priced as low as standard steel discs, but are much more affordable and for those looking at serious braking performance or upgrades, this is an amazing option. For some of the Carbon Ceramic kits, WP Pro offers the discs to work with the factory hat, or alternatively will include the hat assembly and pads. Some kits are even a Plus 1 size to give you more rotor surface for better braking. For price comparison, the front 997 Turbo carbon ceramic rotors to work with the OEM 6piston calipers are $7800. That is in the OEM size of 380x35 but they even do a 'Plus 1' kit to a 392x35mm!

Each big brake kit includes 2 piece rotors, steel braided brake lines, calipers, pads, lightweight brackets and hardware to install. Where available, a Plus 1 rotor size can be had and some kits are available in 4, 6, and 12 piston calipers. Their EX6 6piston caliper as pictured below features an optional carbon fiber vent duct as well. All replacement parts are available for each kit if needed.
