Msport selects only the highest quality premium gray cast iron rotors. Each rotor design is analyzed thoroughly to determine the most effective placement for the cross drilling and slotting to achieve the maximum benefits of venting super heated gases and maintaining a clean pad surface, while at the same time maintaining the structural integrity of the rotor.  Msport rotors resist cracking and warping, ensuring long rotor and pad life. Msport Carbon Metallic Disc Brake Pads meet or exceed the quality of original equipment. Using platform specific formulations and positive mold manufacturing processes, Msport pads provide consistency in performance and braking.
