Detailed Product Description

This disc brake rotor features a vented design with straight vanes that promote efficient heat dissipation during braking, reducing the risk of brake fade. The rotor's nominal thickness of 1.102 inches (28.000 mm) and discard thickness of 1.024 inches (26.000 mm) provide a balance between durability and performance. The fully coated disc and hat surfaces protect against corrosion, which is critical for maintaining rotor integrity and braking efficiency over time. The floating disc mounting system helps accommodate thermal expansion and rotor alignment, contributing to smoother braking operation. With a 5-lug hole pattern and a 4.500 inch (114.300 mm) bolt circle diameter, this rotor is designed to fit specific INFINITI and Nissan models precisely.
