Detailed Product Features and Specifications
This DFC Brake Rotor - Drilled and Slotted - Silver features a vented disc design that enhances cooling by allowing air to flow between the rotor surfaces, reducing the risk of overheating during aggressive braking. The rotor's surface is both drilled and slotted, which helps to evacuate brake dust, gases, and water, maintaining consistent friction and improving braking reliability under various conditions.
The rotor has a nominal thickness of 20mm and a discard thickness of 18.6mm, ensuring a long service life while maintaining safety standards. The hat section is finished in zinc silver, providing corrosion resistance, complemented by an overall rust-resistant coating on the rotor. The rotor measures 288mm in outside diameter with an overall height of 100.5mm, and it features a 103mm center hole diameter to fit securely on the hub.
