A2-148 Girodisc Mercedes 360mm Rear Rotors FAQs:

Will these work with carbon-ceramic packages? No. These rotors are for iron-brake cars only; models with CCB must use CCB-specific components.

Do I need to code or recalibrate anything? No coding required. The rotor dimensions match OEM spec for the listed vehicles.

Can I replace just the rings later? Yes. Use D2-123 or the correct rear ring kit specified for your hat/kit.

Are parking brake shoes affected? No. The rotor hat retains the OEM drum parking brake interface.
