4-Piston Caliper 355x32mm Two-Piece Floating Rotor Big Brake Kit

The Paragon Track Performance Big Brake Kit is a comprehensive rear brake upgrade engineered for the Infiniti Q50 (V37) from 2014 to the present. This kit provides superior braking performance specifically for track day enthusiasts. It includes a complete set of components required to upgrade the vehicle's brake system, utilizing the finest materials and components for both street and track conditions. The kit features Paragon PA025 4-piston calipers, CNC machined from billet 6061-T6 aluminum for outstanding rigidity and a consistent, responsive pedal feel. The calipers utilize Titanium Nitride (TiN) coated pistons for improved durability and stainless steel pistons that act as a thermal barrier to prevent brake fluid boiling. High-temperature piston seals and internal dust seals are incorporated to withstand extreme heat and extend service life, with a hard-anodized finish for wear resistance. These rotors feature a slotted friction face for improved consistency and a hard-anodized aluminum hat. The floating rotor-to-hat mounting system minimizes brake judder, and the rotors are specific to left or right sides for optimized airflow. Included are Paragon P3 “Street/Track” semi-metallic brake pads (manufactured by Winmax Japan), caliper mounting brackets, all necessary hardware, Goodridge DOT-approved stainless steel braided brake lines, and caliper anti-rattle clips. The kit retains OEM e-brake function. Please verify wheel fitment before ordering, as all Paragon big brake kits are custom-made and cannot be returned due to wheel fitment issues. 355mm brake kits generally require 18" or larger wheels, though fitment varies by wheel design; use the provided wheel fitment template for confirmation.
