• Directional slotted and drilled surface for improved brake pad bite and heat management
• Solid disc rotor with zinc silver hat finish and rust-resistant coating
• Nominal thickness of 14.2 mm with a discard thickness of 12 mm
• Five bolt holes with 16 mm diameter and 135 mm bolt circle diameter
• Overall diameter of 334 mm and center hole diameter of 87.5 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is a solid disc brake rotor featuring a directional surface type that combines both drilled holes and slots. The drilled holes help to dissipate heat and gases generated during braking, while the slots assist in removing brake dust and water from the rotor surface. The rotor’s nominal thickness is 14.2 mm, with a discard thickness of 12 mm, ensuring it meets safety standards for wear limits. The zinc silver hat finish provides corrosion resistance, complemented by an overall rust-resistant coating to extend rotor life.

The rotor measures 334 mm in outside diameter and 56.3 mm in overall height, with a center hole diameter of 87.5 mm. It includes five bolt holes, each 16 mm in diameter, arranged on a 135 mm bolt circle diameter, matching the lug pattern of compatible Ford and Lincoln models. This rotor is designed specifically for vehicles requiring a solid rotor type rather than vented.
