Offset modification

Hello I have a 2025 GLC 200 4matic. I have the original rims on it 19x8 ET32.5 front 19x9 ET30 rear I'm thinking about changing to 19x8 ET 22 front 19x9 ET 20 rear. Will such a modification affect any warranty? checked rims will not interfere with the brakes.

Ask the manufacturer to be sure. Incorrect offsets will affect wheel bearing wear and possibly stability if it's different enough.

I doubt it voids the warranty altogether but any dealer or warranty issuer will jump at the chance to deny your claim if it's related to the brakes, wheels, suspension, etc. Something to keep in mind and you will likely have to prove the modifications did not lead to the equipment failure. This is pretty standard for any modifications.
