Product Line Details: DFC Hi-Carbon Alloy GEOMET Coated Rotor

This rotor is part of the DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction, which focuses on high-carbon alloy construction combined with a GEOMET coating. The high-carbon alloy improves rotor durability and reduces the risk of cracking under thermal stress, while the GEOMET coating provides corrosion resistance to extend rotor life. This combination is particularly suited for the braking demands of Mercedes-Benz EQE and EQS models, ensuring consistent performance under various driving conditions.

Technical Description and Specifications

The 900-63199 rotor features a vented design that promotes efficient heat dissipation, reducing brake fade during extended use. With a nominal thickness of 22 mm and a discard thickness of 19.4 mm, it maintains structural integrity throughout its service life. The rotor’s plain disc finish and smooth surface type contribute to even pad wear and quiet braking. Its 378 mm outside diameter and height range of 50.4 to 54.4 mm are engineered to meet the precise fitment requirements of Mercedes-Benz EQE 320, EQE 350, EQS 450, Maybach EQS 680 SUV, and other compatible models. The five bolt holes and 112 mm bolt circle diameter ensure secure mounting, while the 69 mm center hole diameter aligns with factory specifications.
