Drilled and Slotted Brake Rotors

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31000, are performance brake rotors built for BMW applications that need stronger initial bite and consistent stopping feel. The drilled and slotted design helps manage heat, clear debris, and improve pad contact in wet or demanding driving conditions.

Compatible with select BMW 230i, M240i, 320i, 228i, 428i, M235i, and related models, this rotor set is engineered for front and rear use across multiple OE brake configurations.

Installation Notes and Tips

Verify rotor style against the vehicle’s OE brake configuration before ordering, especially on BMW models with aluminum hat, full cast, or M Sport brake setups. Clean the hub mounting surface thoroughly, inspect pads and calipers for wear, and follow proper pad bedding procedures after installation. Part number 7004-31000 is listed for front and rear applications on the covered BMW fitments.
