WP Pro offers the best in big brake kits and braking performance.  Each brake kit is engineered and designed specifically for your vehicle with a bespoke approach.  The lightweight 2 piece calipers are 6061 forged aluminum that undergo a 2000 ton press before they are machined out.  Provide the perfect amount of strength and rigidity to avoid any potential cracking found in monoblock calipers, they are designed for both street and track use.  Each caliper system has been engineered to have proper piston sizing and clamping force based on your vehicle needs.  With special techniques used in the manufacturing of the caliper, further cooling keeps braking performance at an all time high. 

Each rotor is made in the WP Pro foundry using a sand casting technique and then heat treated to 800 degrees celcius for the ultimate in durability and longevity.  Rotors are further designed to have extreme weight savings and heat dissipation.  Each set of WP Pro brakes features our unique Sun Cut design with cross drilled holes.  However standard round rotors are also available in drilled only. The 2 piece floating rotors feature true floating hardware and a billet aluminum hat.  Matched with proper brake pads and steel braided brake lines, the braking performance and style will drastically improve your vehicle.

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!

Now that we have shown they have the track record to back up their products, we can tell you that WP Pro Brakes also carries an entire line of street/track big brake kits. Every make model you can think of from Audi A4, BMW M3, Mini Cooper, Corvette, Ferrari, Mercedes and the new CLA, Ford Focus ST and Fiesta ST, Infiniti, Lamborghini, Lexus, Mazda, Nissan including GT-R, Range Rover, Porsche, Scion including FR-S, Volkswagen, and more. 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.
