Product details


 Description

Paragon Performance 2-Piece Brake Rotors are engineered for drivers who demand exceptional braking performance both on the street and on the track. Built using motorsport-inspired technology, these rotors provide consistent stopping power, improved cooling efficiency, and enhanced durability during aggressive driving conditions. Whether you're upgrading from factory brakes or preparing for serious track use, Paragon rotors deliver the performance, reliability, and control that enthusiasts expect.
Each rotor ring is made from CM-250 high-carbon alloy cast iron for excellent bite, thermal stability, and resistance to cracking under extreme heat. The rings are heat-treated to relieve internal stress and precision CBN-machined to ensure a smooth surface for faster, more consistent brake pad bed-in.

The fully-floating 2-piece design allows the rotor ring to expand during extreme heat cycles, minimizing distortion and maintaining consistent pad contact. Tight tolerances—≤0.03mm lateral runout and ≤2g weight variation—help reduce vibration and brake judder for smooth, consistent braking performance.

The assembly is completed with a lightweight CNC-machined 6061-T6 aluminum hat for strength and reduced weight. Each hat features a Mil-Spec Type III hard anodized finish, available in clear or black, for enhanced wear and corrosion resistance.
