4-Piston Aluminum Caliper Kit

It is specifically designed for the 2016-2018 Mazda Miata. Each caliper in this kit is constructed from a single piece of aircraft-grade aluminum, offering a combination of lightweight design, unparalleled strength, and resistance to corrosion. The calipers feature an opposed-piston design to improve pad grip and reduce uneven wear. Aluminum pistons are utilized for better heat resistance and lighter weight. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers can be mounted directly. The kit includes 2-piece rotors with an aluminum center, reducing rotational mass for quicker braking response and shorter stopping distances. This design also minimizes the chance of rotor warpage by allowing for less restricted expansion and contraction of the outer iron section. The rotors are drilled and vented for optimal performance, and the included brake pads are suitable for street driving. Heavy-duty caliper seals are incorporated for sustained high-temperature use, and stainless steel brake lines prevent expansion under pressure for improved pedal response. The minimum wheel diameter required is 18 inches (457mm), and the rotor outside diameter is 14 inches (356mm).
