Wilwood Red Dynapro 6 Front Brake Package for Mazda 3 (Selected 2004–2013), Drilled and Slotted Rotors with Included Flexlines

Red powder-coated Dynapro 6 calipers distinguish this front kit, which uses drilled-and-slotted 12.88-inch rotor rings on separate aluminum hats. The retained factory hubs, hydraulic output and ABS arrangement must match the Mazda 3 application identified for the package. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. It develops disc brake systems and components, designing and manufacturing calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. A correct conversion matches those individual components to the complete braking system.
