What is a Mercedes-Benz chassis code?

A Mercedes-Benz chassis code is the internal platform identifier Mercedes uses to designate a specific generation and body style. For example, W205 refers to the 4th-generation C-Class sedan (2015-2021), while C205 refers to the same generation in coupe form. Mercedes enthusiasts use chassis codes because they specify the exact platform underneath the car, which determines wheel fitment specifications including offset, width, hub bore, and brake clearance.

How do I find my Mercedes-Benz chassis code?

Your Mercedes-Benz chassis code can be found in several places: on the VIN plate inside the driver's door jamb, in your owner's manual, or by decoding your VIN through Mercedes-Benz online resources. You can also use the chassis lookup tool on this page to identify your platform by model year and trim.

What is the difference between a W205 and a C205 C63?

The W205 is the 4th-generation Mercedes-AMG C63 in sedan form, produced from 2015 to 2021. The C205 is the same generation in coupe body style, produced from 2017 to 2023. Although they share the same underlying platform and powertrain, their wheel fitment specifications differ slightly due to body style, suspension geometry, and brake package, which is why each has its own dedicated fitment guide.

Does FMB Wheels build custom forged wheels for other Mercedes-AMG platforms?

Yes. FMB Wheels builds custom forged monoblock wheels for a wide range of Mercedes-AMG platforms beyond the C63, including the E63 (W212, W213), GT and GT R, SL, S63 (W222, W223), CLS63, G63, GLC63, and more.
