Wilwood Black SRP Front Disc Conversion for Fiat 500 (2012–2015), Dynapro 6 with Lines

Black Dynapro 6 calipers and drilled/slotted 12.19-inch rings identify this Wilwood front package for the stated Fiat 500 applications. The six-piston calipers use BP-10 pads with 0.81-inch-thick rotors, and the kit includes hydraulic flex lines and connection hardware. Separate hats mount the rings on the correct original hubs rather than replacing the vehicle's wheel-bearing assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.

Fitment & Compatibility

Verify the individual Fiat trim and production-year entry using DS939 and the application table. Compare the four-lug pattern, hub register and spindle mounting before checking the wheel's inner envelope. The 15-inch screening size cannot guarantee spoke clearance. Route the included hoses through full steering and suspension movement without contact, then verify caliper centering, rotor runout and hydraulic balance with the retained rear brakes.

Match the individual model, year, submodel and brake configuration in the fitment table below.
