Girodisc Rear Rotors – Mercedes E63 / GT53
The Girodisc A2-248 rear rotor set offers a direct-fit upgrade for the Mercedes E63 and GT53 platforms. Combining track-grade engineering with bolt-on simplicity, these two-piece rotors deliver better heat management, consistent brake feel, and reduced rotational weight—while retaining compatibility with OEM calipers and ABS systems.
Purpose-Built for Street and Track Use
Each rotor uses a curved-vane internal geometry to actively draw cooling air through the disc, preventing hotspots under hard braking. The hub is machined from 6061-T6 aluminum while the friction ring is cast from Girodisc’s proprietary iron alloy—machined in-house from start to finish. A floating mount system with drive pins and anti-noise washers allows expansion and self-centering, enhancing consistency and longevity.

Girodisc A2-248 Rear Rotors FAQs
Do they bolt to stock calipers? Yes, the A2-248 system is designed for OEM compatibility—no modifications needed.
How does the floating design benefit braking? Float allows the disc to expand and self-center under thermal load, reducing stress and improving pedal consistency.
Are replacement rings available? Yes. When rings wear out, you can replace just the ring while reusing the hub and hardware to save cost.
Is the rotor sold individually or as a pair? The A2-248 kit includes both rear rotors and is sold per pair.
What kind of pads and fluid should I use? To get the most out of these rotors, use a high-temperature brake fluid and performance brake pads; they help manage fade and keep braking consistent over multiple laps.
Choose the Girodisc A2-248 for your Mercedes E63 or GT53 and enjoy advanced braking performance, precision engineering, and long-term serviceability built for the road and track.
