Girodisc Mercedes E63 / GT53 Rear Rotors (Dimpled & Slotted) The Girodisc A2-248DS Rear Rotors are a direct replacement for the OEM discs on the Mercedes E63 and GT53. These precision-machined, dimpled and slotted rotors deliver superior braking performance, enhanced cooling, and a substantial reduction in weight. Designed to bolt directly to the car with no modifications required, they maintain the factory brake bias and ABS efficiency while improving response and durability. Performance Upgrade & Weight Reduction Each Girodisc assembly is engineered to be approximately 8.1 lbs lighter per rotor than the factory units (16.6 lbs vs. 24.7 lbs). This significant reduction in unsprung and rotational mass allows for improved acceleration, sharper turn-in, and better suspension feedback. Engineering Excellence The central hat section of the rotor is crafted from 6061-T6 aircraft-grade aluminum, precision-machined and anodized for strength and corrosion resistance. The outer disc is made from Girodisc’s proprietary high-carbon cast iron alloy, poured and machined in the USA to exacting tolerances. The dimpled and slotted surface design improves pad bite, reduces glazing, and enhances gas evacuation during high-temperature operation. Floating Mount System Girodisc rotors utilize a fully floating mount system that connects the iron ring to the aluminum hat using 10 cadmium-plated steel drive pins. The assembly is secured by class 12.9 cap screws and hardened washers, allowing axial and radial movement as the rotor expands under heat. Anti-noise spring washers eliminate rattle and vibration, maintaining quiet operation while preserving true race-grade performance.
