This is the R1 Carbon Geomet Series rotors (you choose Front or Rear).
These will provide the ultimate stopping power needed for demanding driving and harsh conditions.
They are made with more Carbon, Chromium, and Molybdenum (good stuff!), which makes these High Carbon rotors offer increased braking performance and strength.
Additionally, a center split core casting provides greater stability (from warping).
Lastly the special Geomet coating protects against rust while extending rotor life.
Each rotor is "Mill" balanced and double disc ground to reduce thickness variations in the surface of the braking surface for smoother stopping, minimal vibration, and improved break-in.
This price is per pair!
Same diameter as stock and has the factory Jeep JK with a Dana 30 or 44 in all models 2007-2018 bolt pattern of 5 on 5" (127mm).
