Keep rear braking smooth and balanced with the DYNAMIC FRICTION brake rotor (P/N 634-63104), a DFC GEOSPEC coated, drilled-and-slotted disc brake rotor built as a rear replacement for the 2017-2021 Mercedes-Benz AMG GT, the 2015-2021 Mercedes-Benz C63 AMG, the 2015-2021 and 2023 Mercedes-Benz C63 AMG S, and the 2013-2019 Mercedes-Benz SL63 AMG and SL65 AMG. It is designed to meet the same form, fit, and function as OEM brake rotors, so it drops into the rear position on the listed applications.
Rotors wear on both sides of the axle, so replacing the left and right rear rotors together as a matched set is recommended for even, balanced braking.
What vehicles does the DYNAMIC FRICTION brake rotor 634-63104 fit?
It is a rear replacement for the 2017-2021 Mercedes-Benz AMG GT, 2015-2021 C63 AMG, 2015-2021 and 2023 C63 AMG S, and 2013-2019 SL63 AMG and SL65 AMG. See the Buyer's Guide tab for engine details.
Is this a front or rear rotor?
This disc brake rotor is cataloged for the rear position on the listed applications.
Is the rotor drilled and slotted?
Yes. It is a DFC GEOSPEC coated rotor that is drilled and slotted, with a non-directional finish to promote faster break-in and smoother stops.
What does the GEOSPEC coating do?
The GEOSPEC coating is designed to provide corrosion protection superior to zinc and conventional painting, helping the rotor resist rust.
Should I replace both rear rotors at the same time?
It is recommended. Replacing the left and right rear rotors together as a matched pair helps keep braking even and balanced across the axle.
