Featuring a vented rotor construction with pillar-style vanes, these rotors promote efficient airflow to reduce heat buildup during aggressive braking. The cross-drilled and slotted surface pattern helps evacuate brake dust, gases, and water, improving pad bite and reducing brake fade. The coated hat finish provides corrosion resistance, helping maintain rotor integrity over time. With a nominal thickness of 20.0 mm and discard thickness of 18.0 mm, these rotors meet strict OEM specifications for durability and performance. The 5-lug hole pattern with a 114.3 mm bolt circle diameter ensures proper fitment and secure mounting. This rotor is designed with a floating\/dih disc mounting style to allow slight movement, reducing stress and improving braking consistency.\u003c\/p\u003e\u003ch2\u003eStopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors Product Line\u003c\/h2\u003e\u003cp\u003eThe StopTech Sport Cross-Drilled \u0026amp; Slotted Disc Brake Rotors line focuses on delivering enhanced braking performance through advanced rotor surface technology. The combination of cross-drilled holes and precision slots improves heat dissipation and pad cleaning, which is critical for performance-oriented vehicles like the Subaru WRX STI and Impreza.
