The rotor features a directional surface with both drilled holes and slots, which help to evacuate gases, dust, and water for consistent braking performance. The zinc black coating on the hat provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 25.8 mm and a discard thickness of 24.4 mm, this rotor meets precise dimensional standards for safe operation. The rotor's 338 mm outside diameter and 73 mm height ensure proper fitment on compatible BMW models. The 5-lug bolt pattern with 14.9 mm diameter holes and a 120 mm bolt circle diameter matches factory specifications for secure installation.\u003c\/p\u003e\u003ch2\u003eAbout the DFC Brake Rotor - Drilled and Slotted - Black Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Black product line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This line is designed to provide enhanced braking performance and durability for vehicles requiring vented rotors with directional surfaces. The black zinc finish on the hat offers additional protection against rust, making these rotors suitable for drivers seeking reliable stopping power and longevity in demanding conditions.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for worn or warped rotors on BMW 135i, 135is, 328i, and 330i\u003c\/li\u003e\n\u003cli\u003eImproves heat dissipation to reduce brake fade during aggressive driving\u003c\/li\u003e\n\u003cli\u003eHelps prevent brake judder caused by uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eReduces corrosion-related rotor damage with rust-resistant coating\u003c\/li\u003e\n\u003cli\u003eMaintains consistent braking performance in wet or dusty conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the rotor is compatible with your specific BMW model and verify the part number 633-31085L before installation. Clean the hub surface thoroughly to prevent uneven rotor mounting. Use proper torque specifications on the 5 lug bolts to secure the rotor. It is recommended to replace brake pads simultaneously to optimize braking performance. After installation, perform a bed-in procedure to condition the new rotor surface.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDynamite Friction manufactures the DFC Brake Rotor - Drilled and Slotted - Black to meet OEM standards for fit and function.
