## Description

Girodisc A2-207 rear brake discs (358 × 32 mm) optimize consistent braking performance during spirited driving on the Mercedes-AMG GT S, C, and R models with carbon-ceramic rotors (2016+), the Mercedes E63 (W213) with carbon-ceramic rotors (2017+), Mercedes S63 and S65 (W222) with carbon-ceramic rotors (2014–2020), Mercedes SL63 (R231) with carbon-ceramic rotors (2012–2017), and Mercedes SL65 (R231) with carbon-ceramic rotors (2012–2018). Their cast-iron tracks and aluminum cups form a floating assembly designed to handle thermal stresses and facilitate replacement of the tracks when worn. Sold in pairs, with one left and one right disc.
These rotors are intended for the rear axle of compatible vehicles in the configuration listed below. They retain the compatible caliper mounting; any required spacers and brake pad specifications must be observed.
The curved internal cooling fins channel air through the rotor to dissipate heat during repeated braking. The floating mounting minimizes stresses caused by thermal expansion differences between the rotor and the housing and helps the rotor center itself between the brake pads, maintaining consistent contact under heat.
The hub is made of 6061-T6 aluminum. The high-strength steel drive pins are cadmium-plated to resist corrosion. They are secured by Class 12.9 bolts and hardened washers. Spring washers minimize cold-mounting noise while allowing the necessary compression for the floating mount.
New pads must be installed with new rotors or brake tracks. Their shape and compound must match the mounting, cast iron, and intended use; adhere to the specific requirements of this part number and perform the prescribed break-in procedure.
On compatible vehicles originally equipped with carbon-ceramic rotors, this pair provides a conversion solution to high-quality cast-iron rotors. It allows you to remove and store the expensive original carbon-ceramic rotors to preserve them during heavy-duty use, while reusing compatible calipers. Use new brake pads suitable for cast iron and adhere to the pad shapes and any spacers specified by the part number. Replaceable brake pads reduce the cost of replacing braking surfaces in heavy-duty applications and offer a choice of linings to tailor bite and pedal reaction to the intended use.

Brake Pads and Brake Systems for Compatible Vehicles
Choose brake pads whose shape is compatible with the calipers, track, and/or A2-207 rotors, and whose compound is suitable for sport driving or track use. The Endless, pagid Racing, or Ferodo Racing ranges may be considered after verifying the appropriate part number.
For intensive use, we recommend compatible aviation-grade flexible hoses and high-performance brake fluid that meets the vehicle’s specifications, along with proper bleeding and fluid replacement. This recommendation complements the mounting compatible with the original hydraulic system.
Maintenance of the Girodisc mounting on compatible vehicles
Replacing the pads alone helps keep the rotors in good condition. Reusing a rotor for up to three pad replacements is subject to inspection of its condition, its mounting hardware, and the mounting instructions; this number does not constitute a guaranteed service life. Use new mounting hardware with each pad replacement.
FAQ — Girodisc A2-207 for Compatible Vehicles
What are the sizes of the A2-207 discs for my vehicle? The part number shown measures 358 × 32 mm and is mounted on the rear axle. The diameter alone is not sufficient: also check the brake system type and mounting requirements.
Is the product sold in pairs? Yes. It includes a left and a right disc for the same axle. Both discs come with their hubs.
Do I need to replace the brake pads on my vehicle?Yes. Always install new brake pads with new rotors or new brake pads. Their shape and compound must be compatible with the A2-207 rotor and the calipers. Then break in the rotors and pads according to the prescribed procedures.
How do I identify the left and right sides? Girodisc rotors come with a label attached to each rotor: LEFT for the left side and RIGHT for the right side, as viewed in the direction of travel. On a left-hand-drive vehicle, “LEFT” corresponds to the driver’s side and “RIGHT” to the passenger side. Follow these labels and the instructions. On models with curved internal fins, the rolling direction depends on this internal ventilation; the surface grooves alone are not sufficient to determine the side.
How do I break in this mounting on my vehicle? Follow the Girodisc procedure and the brake pad manufacturer’s instructions to build up an even transfer ply. The PDF documents below detail installation and break-in.
PDF Documents for Mounting and Break-in
We have included two PDF documents below: an instruction manual for installing and running in the discs, and an instruction manual for installing new tracks on existing bowls. Consult the document that applies to your specific task before you begin.
