Many components surrounding the brake system are sensitive to heat. Wheel bearing operating temperature is lowered compared to standard 1-piece rotors. Instead, better cooling in the brake system and surrounding components can be achieved due to heat conductivity of aluminum. Using lightweight aluminum in the mounting hat section of the rotor will not create any negative effects on thermal characteristics of the brake system. The lightweight aluminum hats replace heavy cast iron center sections found in standard 1-piece rotors. Unnecessary material on the hats are taken out for additional weight reduction, while maintaining proper structural integrity and strength. This reduces unsprung and rotational mass, and improves overall acceleration, braking and handling of the vehicle.
While we always aim for color consistency, potential slight color variations may exist from batch to batch due to the nature and variables in the anodizing process. ***Type III Hard anodizing of aluminum is considered as a functional surface coating process. Hard anodized surface will hold up better when exposed to ultraviolet (UV) light, and is even more important if the vehicle is exposed under outdoor conditions frequently. Hard anodized surface will last longer than black anodized surface, and is highly recommended for track / race applications. Hard anodizing allows for a thicker hard coat which provides advanced corrosion resistance and low-maintenance durability. Hard anodized surface is harder, thicker, and more wear and scratch resistant. Mil-spec hard anodizing (MIL-A-8625 Type III) will not discolor under extreme heat, while black anodizing is more prone to discoloring under heat (> 392F / 200C).
Paragon aluminum hats are precisely machined from lightweight 6061-T6 aerospace grade aluminum for high strength and durability under extreme conditions, then anodized to increase resistance to wear and corrosion. Rotors that utilize the H-Bobbin, T-Bobbin, and S-Bobbin mounting systems are fully-floating, which allow the rotor to "float" in both radial and axial directions according to temperature variations.Įach aluminum hat is specifically designed for the application and made in-house with the latest technology in CNC machining. The rotor is self-centered with the pads throughout the heat cycle and therefore allows consistent braking power and pedal feel. This reduces deformation and cracking under extreme track conditions.
With the use of floating hat & hardware, the floating 2-piece design allows expansion of the rotor assembly. In standard 1-piece rotors, every component is fixed and will easily distort under heat. Under high temperature conditions, iron tend to expand and increase in diameter. Latest technologies and finest materials were used to ensure the rotors to perform and last under extreme conditions.
Developed with performance, quality, and longevity in mind, these 2-piece rotors offer superior braking performance and cooling efficiency optimized for a wide range of applications including club racing, time attack, autocross, HPDE, etc, while still maintaining street drivability. After extensive development and track / race testing, Paragon Performance launched a new range of high performance 2-piece rotors.
