Detailed Product Description

The StopTech Sport Cross-Drilled Disc Brake Rotors are precision-engineered replacement rotors designed specifically for Subaru Impreza and Legacy vehicles. Featuring a vented rotor design with straight vanes, these rotors promote efficient airflow to reduce heat buildup during braking. The cross-drilled surface pattern helps to evacuate gases and debris, improving pad bite and overall braking consistency. The coated hat finish provides added protection against corrosion, extending rotor life in various driving conditions. With an outside diameter of 289.6 mm and a nominal thickness of 17.9 mm, these rotors meet OEM specifications for fit and function. The rotor includes five lug holes on a 100 mm bolt circle diameter, ensuring proper mounting and alignment. The floating disc mounting design allows for slight rotor movement, which can help reduce brake judder and improve pedal feel.
