PARAGON Track Performance Replacement Rotors 4-Piston BBK (PA055)

These rotor rings are direct replacements for the Paragon PA055 4 piston front big brake kit. Designed specifically for track and race use, they deliver superior braking performance, cooling efficiency, and long-term durability. Each set includes rotor rings for both sides, new attachment hardware, and assembly instructions for a complete and hassle-free rebuild.

Key Features:

• Direct replacements for Paragon PA055 front brake kits

• Includes rotor rings (pair), new attachment hardware, and assembly instructions

• Fully-floating 2-piece design – allows for thermal expansion and reduced distortion

• Directional ventilation vanes – improves airflow and cooling efficiency by up to 30%

• Made from CM-250 high carbon alloy cast iron – excellent bite, thermal stability, and strength

• Heat-treated and stress-relieved – reduces rotor deformation and vibration

• Precision CBN-machined surfaces – ensures smooth break-in and consistent performance

• Lateral run-out held under 0.03mm and balanced within 2 grams – minimizes vibration

• Slotted design – maintains clean pad contact, dissipates gases and heat, and performs better in wet conditions

• Lighter than most OEM rotors – reduces unsprung mass and improves handling

• Helps minimize brake fade and judder during extended track sessions

Built for drivers who demand reliable, repeatable performance under extreme conditions.
