Custom forged wheels for Mercedes GLC 63 AMG

The Mercedes GLC 63 AMG generation we cover

One row per published generation, from the oldest to the most recent. Each measurement comes from the generation's page, which cites its sources and gives the fitment of each version. These measurements help you recognise your car; they are not a recommendation, and Onyx does not advise any specific offset.

Onyx entry price: the set of four monoblock forged wheels in the smallest diameter of our price list that covers the smallest original diameter recorded; the other diameters and the two-piece construction are on each generation's page. Amounts in pounds: our checkout on 4 October 2026, before the carrier's clearance fee and any import duty. The amount shown at checkout is the one charged for your order.

Publication rule: a measurement is shown only if a primary source gives it (a manufacturer's document, an official vehicle type record, an original parts catalogue, the maker of the original wheel) without another primary source contradicting it, or if two independent specialist sources agree without a primary source contradicting them. The press and forums do not count. Measurements checked on 21 October 2026.
