This rotor is solid rather than vented, providing a robust and reliable braking surface. The drilled and slotted design helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The directional surface pattern ensures consistent contact with brake pads, enhancing stopping power and pedal feel.\u003c\/p\u003e\u003cp\u003eConstructed with a nominal thickness of 10 mm and a discard thickness of 8.4 mm, this rotor maintains structural integrity throughout its service life. The rotor’s outside diameter measures 284 mm, with an overall height of 61.1 mm, fitting precisely to the specified BMW models. The zinc silver hat finish includes a rust-resistant coating to help prevent corrosion and extend rotor life.\u003c\/p\u003e\u003ch2\u003eDFC Brake Rotor - Drilled and Slotted - Silver Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors with enhanced surface treatments such as drilling and slotting to improve braking efficiency and heat management.
