4-Piston Big Brake Kit with 2-Piece Rotors

The Paragon Performance 4-Piston Front Big Brake Kit is a complete, track-ready upgrade engineered specifically for the Mazda RX-7 (FD3S). This kit leverages the same Paragon PA055 4-piston calipers utilized by Team Honda Research West in the demanding 25 Hours of Thunderhill endurance race, demonstrating their proven performance and durability in extreme conditions. The piston sizes are optimized for the FD3S, ensuring full compatibility with the OEM ABS system and master cylinder, and it is also compatible with the OEM rear brakes. This kit delivers exceptional braking performance with reliable heat resistance, a strong bite, and consistent pedal feel even under extended use. The kit includes one pair of Paragon PA055 4-piston calipers, one pair of Paragon 2-piece rotor assemblies with hard anodized 6061-T6 aerospace grade aluminum hats, and one set of Paragon P3 "Street/Track" semi-metallic brake pads manufactured by Winmax Japan. Also included are caliper mounting brackets with all necessary hardware, a pair of Goodridge DOT-approved stainless steel braided brake lines, caliper anti-rattle clips, and a detailed installation manual, making it a complete, pre-assembled front axle kit for straightforward, bolt-on installation.
