Set of 4: Each product is sold as a complete set of four pieces, one piece for each wheel.
AMG builds are where Mercedes stops being a luxury car and becomes a performance statement. C63, E63, G63, and GT owners tend to run aggressive aftermarket setups — Vossen, Brabus monoblock, HRE, or Forgiato wheels on staggered fitments. The AMG badge needs to hold its own in that company.
The floating center cap keeps the AMG emblem upright as the wheel turns. Counter-rotating mechanism, logo stays level at any speed. Set of 4, built for AMG vehicles on aftermarket wheels with large center bores.
Most AMG aftermarket setups run 20–22" wheels. Center bore sizes vary significantly by wheel brand. Measure your bore before ordering.
Note on Brushed & Polished Aluminum: Machined metal — not painted plastic. $50 upcharge reflected in the price.

You need one of your current caps, a ruler or tape measure, a sheet of paper and a pencil.
Tap your size to select it.
Pick the size closest to your number. A few millimeters either way is normal. 177.8mm (7") isn't available in Brushed or Polished Aluminum.
Start at the last whole number, then count the little lines past it. Each one adds 1/16 in. Example: 5 and 11 little lines is 5 11/16 in, our 145mm size.

Flip the cap over. Measure the raised inner ring that holds the metal clip, outside edge to outside edge, straight across the middle.
Don't measure the hole inside the ring or the wide outer cap.
Tap your back ring size to select it.
