Replacement oversized rotor for the Braking EPTA BATFLY Oversized Brake Rotor Kit. The brake rotor's outer track mounts to the newly designed carrier at 6 points; both the carrier and the rivets are now aluminum instead of stainless steel which reduces weight. The carrier is now made of 7075-T6 aluminum like the rivets; this allows for optimal shape, reduced weight and higher rigidity. New rotor-to-hub coupling geometry that allows the rotor stems to slide in radial direction, which improves the response to stresses and deformation at high temperature - more homogeneous disk temperature without increasing weight. Increased heat dissipation as it has less external perimeter and an area not covered by the pad - when the internal pad touches the rotor, the external does not and vice versa, allowing heat to dissipate from each side.
