Detailed Product Description

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (127.44156R) feature a vented rotor design with straight vanes that promote efficient airflow to dissipate heat generated during braking. The cross-drilled and slotted surface helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent brake pad contact and reducing the risk of brake fade. The coated hat finish protects the rotor’s central hub from rust and corrosion, extending the rotor’s service life. These rotors are designed with a floating disc mounting system, which allows slight movement between the rotor and hub to improve alignment and reduce stress on the braking components.
