Detailed Product Features and Specifications

This Brembo PRIME disc brake rotor is constructed from high carbon cast iron, which provides a balance of strength and thermal conductivity essential for consistent braking performance. The composite vented design helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during aggressive driving or heavy braking conditions. The rotor surface features a slotted and drilled pattern, which aids in removing brake dust, gases, and moisture, contributing to improved brake pad contact and performance.

With a nominal thickness of 36 mm and a discard thickness of 33 mm, this rotor maintains structural integrity over its service life. The rust resistant coating protects the rotor from corrosion, helping to maintain appearance and function over time. The rotor fits vehicles with a 5-lug stud pattern and a center hole diameter of 67 mm, ensuring proper alignment and fitment.
