Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to improve brake cooling and reduce fade through enhanced rotor surface features. The combination of cross-drilled holes and precision slots helps evacuate gases, dust, and water from the braking surface, maintaining consistent pad contact. This rotor line is coated on the hat area to resist corrosion, extending rotor life and maintaining appearance. The solid rotor design provides structural integrity while supporting effective heat dissipation for vehicles like the Nissan Maxima and INFINITI I30 and I35.
