6-Piston Big Brake Kit

Developed with a focus on performance, quality, and longevity, this kit utilizes the finest materials to ensure optimal function under both street and demanding track conditions. The kit includes Paragon PA015/PA035 6-piston calipers, fully-floating 2-piece rotor assemblies with hard-anodized aluminum hats, P3 "Street/Track" semi-metallic brake pads, caliper mounting brackets, and Goodridge DOT-approved stainless steel braided brake lines. The calipers are CNC machined from billet 6061-T6 aluminum, featuring titanium nitride (TiN) coated pistons for durability and smooth travel, as well as staggered piston bore sizes for balanced braking and even pad wear. Stainless steel pistons act as a thermal barrier to help prevent brake fluid boiling and fade, while high-temperature piston seals and internal dust seals withstand extreme heat. They are constructed from CM-250 high-carbon alloy cast iron with a slotted friction face for enhanced consistency and wet-weather performance. The hard-anodized aluminum hats reduce unsprung weight and resist wear and discoloration. The P3 "Street/Track" brake pads offer optimum bite, modulation, thermal stability, and durability. For this specific kit, the 355x32mm rotors generally require 18" or larger wheels, though fitment can vary by wheel design. It is critical to verify wheel fitment using the provided template before ordering, as all Paragon big brake kits are custom-made to order and cannot be returned due to wheel fitment issues. The kit excludes Shelby GT350/GT350R/GT500 models. Application is for 2015-2023 Ford 6th Gen Mustang S550 Ecoboost/GT/GT Performance Pack/Mach 1 Front and 2024+ Ford 7th Gen Mustang S650 EcoBoost/GT/Dark Horse Front.
