Wilwood 2006-2015 Mazda MX-5 Miata NC Narrow Dynapro Radial4/MC4 Rear Big Brake Kit with Parking Brake (12.88in)

The Wilwood Narrow Dynapro Radial4/MC4 rear big brake kit for the 2006-2015 Mazda MX-5 Miata NC replaces the factory rear brakes with four-piston calipers and 12.88-inch rotors. The larger swept area and stiffer caliper give you a firmer pedal, steadier repeat stops and better heat handling on the street and at the track. This version is set up so the car keeps a working parking brake.
