The owner's post in the MBWorld C450/C43 fitment guide presents his C450 AMG wagon on Rotiform OZR wheels, 19x8.5 ET45, with 15mm spacers all around and 245/35/19 Michelin Pilot Sport 4S tires, lowered on H&R springs. His profile lists the car simply as a C450; the C450 AMG was sold for the 2016 model year only, which is the year recorded here. The black paint and gunmetal wheel finish are from the owner's photos.
