• Cross-drilled and slotted surface for efficient heat and gas dissipation
• Vented rotor design with pillar-style vanes for optimized cooling
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better rotor alignment and reduced warping
• Compatible with 5-lug wheel setups, 120mm bolt circle diameter
• Nominal thickness of 31.9 mm and discard thickness of 30.0 mm
• Outside diameter of 355.4 mm (13.992 inches) for precise fitment

Detailed Product Features and Specifications

This StopTech rotor features a vented design with pillar-style vanes that promote airflow to reduce heat buildup during braking. The cross-drilled and slotted surface improves pad bite and helps evacuate brake dust and gases, which can otherwise reduce braking efficiency. The coated hat finish protects the rotor’s central hub from rust and corrosion, maintaining structural integrity over time. With an overall height of 49.7 mm and a center hole diameter of 67.4 mm, this rotor is engineered to exact OEM specifications for a direct replacement on compatible vehicles.
