Description

All calipers feature 1-piece construction from a solid billet of aircraft-grade aluminum for lightweight, unparalleled strength, and freedom from corrosion. The aluminum pistons provide superior heat resistance and uncompromised operation. This rear kit features 4-piston lightweight aluminum calipers, an improvement over OEM designs for better pad wear and caliper rigidity. It includes CNC machined carbon steel caliper brackets to ensure proper bolt-up to OEM locations. The kit utilizes two-piece rotors for lightweight, fade-free performance and effective grip, suitable for both track and daily driving. It comes standard with NAOC Ceramic pads, offering optimal braking performance for street and occasional track use, reducing brake dust by over 50% and minimizing noise and rotor wear. Optimal operating temperatures are between 194°F - 1022°F. D.O.T. compliant stainless-steel braided brake lines are standard, preventing expansion under pressure for quicker pedal response and a firmer pedal feel compared to stock rubber lines. The Procomp system offers a choice between Slotted or Cross Drilled rotors; Slotted rotors are recommended for track use, while Cross Drilled rotors are recommended for daily drivers due to their cooler running temperatures. Ksport Big Brake kits are built to order, with production and delivery typically taking 4-6 weeks. This kit is specifically designed for the 2016-2018 Mazda MX-5 Miata. Fitment may vary by trim level, and buyers are encouraged to confirm compatibility using the search bar or by contacting customer support. If a fitment issue arises due to a sales team recommendation or an order error, returns will be handled with the aim of making things right, potentially without restocking fees if the item is in like-new condition.
