Cross drilling of conventional mass-produced brake rotors often leads to heat cracks and rotor failure. To solve this problem, Spoon undertook extensive research and design, eventually developing a flap-type, cast-metal rotor. A uniform distribution of carbon content in the metal maximizes heat resistance and manufacturing consistency between rotors. Holes are cast during the rotor casting process, rather than cross-drilled, providing superior strength and cooling performance. In comparison to stock rotors, these will resist and dissipate heat better, resist warpage and cracking better, last longer, and are lighter. Price for 1 Rotor
