Designed with a directional slotted and drilled surface, this rotor enhances heat dissipation and braking consistency under demanding conditions.

• Directional slotted and drilled disc surface for improved heat and gas dissipation
• Black zinc-coated hat finish for corrosion resistance
• Nominal thickness of 20 mm with discard thickness at 18.4 mm
• 300 mm outside diameter and 50.6 mm height for exact fitment
• 5 bolt holes with 16.7 mm diameter and 112 mm bolt circle diameter
• Rust resistant coating to extend rotor life
• Center hole diameter of 67 mm for proper hub alignment

Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Black from Dynamite Friction is designed specifically for vehicles such as the BMW 228i Gran Coupe, 228i xDrive Gran Coupe, and Mini models including the Aceman, Cooper Clubman, Cooper Countryman, X1, and X2. This disc brake rotor features a directional surface with both drilled holes and slots, which work together to reduce brake fade by allowing heat and gases to escape more efficiently during braking. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring a long service life before replacement is necessary.

The rotor’s hat is finished with a zinc black coating that provides rust resistance, helping maintain structural integrity and appearance over time. With a 300 mm outside diameter and 50.6 mm height, this rotor matches OEM specifications for the listed BMW and Mini models. The 5 bolt holes, each 16.7 mm in diameter, and a bolt circle diameter of 112 mm ensure proper mounting and fitment. The center hole diameter of 67 mm aligns precisely with the vehicle hub for secure installation.
