These rotors provide reliable braking performance with enhanced heat dissipation and improved pad bite through their vented, slotted, and cross-drilled design.

• Cross-drilled and slotted surface for efficient heat dissipation and debris removal
• Vented rotor design to reduce brake fade during extended use
• Coated hat finish to resist corrosion and extend rotor life
• Compatible with 5-lug wheel setups, mounting bolt circle diameter of 120.7 mm
• Nominal outside diameter of 305 mm (12.008 inches) and overall height of 67.9 mm (2.673 inches)

Detailed Product Features and Specifications

This StopTech rotor features a vented design with straight vanes that promote airflow to maintain optimal operating temperatures. The slotted and cross-drilled surface improves braking response by allowing gases and dust to escape, reducing pad glazing and maintaining consistent friction. The rotor’s nominal thickness is 20.0 mm (0.787 inches), with a discard thickness of 18.5 mm (0.728 inches), ensuring a long service life before replacement is necessary. The coated hat finish protects against rust and corrosion, which is especially important for vehicles exposed to moisture and road salt.
