Product details

 Description

Paragon Track Performance 4-Piston Big Brake Kits are engineered for enthusiasts who demand stronger, more consistent braking performance for both street and track driving. Designed with track-day durability and precision in mind, these kits provide improved stopping power, superior heat management, and excellent pedal modulation under demanding conditions. Every component is carefully selected to deliver a reliable and complete braking upgrade that performs confidently during aggressive driving and extended track sessions.
Paragon PA055 front or PA025 rear forged 4-piston calipers deliver powerful, evenly distributed clamping force for consistent braking performance. Each caliper features application-specific piston sizing to maintain proper brake balance and seamless compatibility with factory ABS systems and master cylinders, allowing the system to integrate smoothly with your vehicle while significantly improving braking capability.

Each kit includes Paragon fully-floating 2-piece rotor assemblies designed to maximize cooling and durability under extreme braking loads. The rotors feature 48 directional ventilation vanes that actively draw cool air through the rotor, improving heat dissipation and allowing the system to run up to 30% cooler than comparable OE rotors. The floating rotor design allows thermal expansion during heavy braking, reducing rotor distortion and maintaining consistent pad contact.

The kit is completed with premium motorsport-grade components including stainless steel bobbins, hard anodized 6061-T6 aluminum rotor hats, stainless steel braided brake lines, and Paragon P3 Street/Track semi-metallic brake pads manufactured by Winmax Japan. Delivered as a complete pre-assembled axle set, the Paragon Track Performance 4-Piston Big Brake Kit offers an easy installation and a substantial upgrade in braking performance, durability, and driver confidence.
