4-Piston Front Big Brake Kit

It's a direct bolt-on replacement requiring no modifications to your existing setup. Constructed for durability and performance, the kit features 4-piston calipers crafted from a solid billet of aircraft-grade aluminum, ensuring a lightweight yet incredibly strong and corrosion-resistant assembly. The calipers utilize aluminum pistons for improved heat resistance and consistent operation. The accompanying 2-piece rotors, measuring 330mm (13") in diameter with a 432mm (17") minimum wheel requirement, are vented and slotted, featuring an aluminum center to reduce rotational mass, improve braking response, and shorten stopping distances. The 2-piece design also minimizes rotor warpage by allowing for less restricted expansion and contraction. Additional benefits include opposed-piston caliper design for superior pad grip and reduced uneven wear, heavy-duty caliper seals for sustained high-temperature use, and stainless steel brake lines that resist expansion under pressure for quicker pedal response. Reinforced carbon steel caliper brackets ensure these larger-than-OEM calipers mount directly to factory locations. This kit is specifically designed for the 2016-2018 Mazda Miata MX-5.
