***Please verify wheel fitment / clearance before ordering. All Paragon big brake kits are custom made/packaged to order, and cannot be returned due to wheel fitment issues.

Wheel Fitment Template Download (PDF): 355x32mm / 380x32mm

> How to use the wheel fitment template (PDF)

**355mm brake kits generally require 18" or larger wheels, while 380mm brake kits generally require 19" or larger wheels. Fitment varies due to different specs / wheel design. Verify fitment with wheel fitment template.

Alcon CAR98 Mono4 Rear brake calipers


  • 2-piece design
  • Superior braking and cooling efficiency
  • Features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking
  • Made of CM-250 special formulated high carbon alloy cast iron. Allows for an optimal bite, thermal characteristics, high-temperature strength, and durability
  • Heat treated to release stress in the rotor to avoid deformation and vibration
  • State-of-the-art CBN surface machining to ensure better break-in with new brake pads
  • Excellent thermal capacity to minimize brake fade

Paragon Alcon CAR98 Rear Brake Kit - 2-pc Rotor

Curved Directional Ventilation Vanes

Features 48 directional ventilation vanes to create suction and turbulence, and guide cool air through the rotor to achieve better heat dissipation and increased resistance to cracking under harsh track conditions. Each rotor is left or right side specific, and the ventilation vanes are optimized to spin in a particular direction to pump the maximum amount of cool air through the rotor. This design allows the rotor to run up to 30% cooler than O.E. rotors and increases cooling efficiency by up to 30% over standard 1-piece units. Brake fade and judder are minimized during extended sessions. This means the brake system can withstand heavier track usage and provide consistent braking performance lap after lap.


Slotted Friction Face

Slotted rotor face pattern improves brake consistency by constantly cleaning the contact surface and dissipate heat generated, and gases released when the pads come into contact with the rotors. Slotted rotors have a superior advantage over blank rotors in wet or raining conditions by preventing water films to form between the brake pad and rotor surface.
