The rotor’s surface is both drilled and slotted, which assists in channeling away brake dust, gases, and water, improving braking consistency and pad bite. The directional brake surface is designed to optimize performance when installed in the correct orientation.\u003c\/p\u003e\u003cp\u003eThe rotor measures 294 mm in outside diameter and 75 mm in overall height, with a nominal thickness of 19 mm and a discard thickness of 17.4 mm, ensuring it meets precise fitment requirements for the BMW Z4. The zinc silver hat finish provides corrosion resistance, complemented by an overall rust-resistant coating to extend rotor life. The five bolt holes, each 14.2 mm in diameter, align with a 120 mm bolt circle diameter, matching the BMW Z4’s hub specifications.\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 from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This product line is designed to offer enhanced heat management and braking performance for vehicles like the BMW Z4, where maintaining consistent brake response is critical.
