Stock vs. JHM
-Rotor Weight: Stock = 13.75lbs(each), JHM = 11.5lbs(each) - LIGHTER,2.25 lbs less each.
-Rotor Cooling Air-gap: Stock = 6.35mm(.250"), JHM = 13mm(.511") - LARGER for better cooling
-Rotor Cooling Center Fin Design: Stock = Straight Fin, JHM = Airfoil - MORE EFFICIENT for better cooling
-Rotor OD: Stock = 330mm(12.9"), JHM = 330mm(12.9") - SAME
-Rotor Thickness: Stock = 22mm(.866"), JHM = 22mm(.866") - SAME
-Bolt pattern: - SAME (fits like an OEM rotor would)

INCLUDES: 2 - JHM 2-piece Lightweight Rear Rotors. (Each rotor weighs 2.25lbs less than stock for a total of 4.5lbs weight savings.)
