ET-30 at the rear is the reason this is a three-piece. Negative offset means the mounting face sits inboard of the wheel's centreline, so almost the whole barrel hangs outboard — that is where the lip depth in these photos comes from. Cutting that from a single forged blank would mean starting with far more material than ends up in the finished wheel; splitting it lets the lip be built to depth instead. Front and rear also run different hub bores, 75 mm and 66 mm, so the two halves of the set are not interchangeable even though they share the same bolt pattern.

That is the part of this build worth talking about. The specification itself is straightforward: 18×8.5, 5×114.3, ET-10, 75 / 66 mm bore, Gold Painted Face, Polished Outer Lip, Machined Silver Inner Barrel.
Forging gives a denser grain structure than a cast wheel of the same weight, which is why the spoke sections can be cut this thin without losing load capacity. This one is rated to 850 kg.
Every set ships with a serial engraved with size, offset, centre bore and load rating, tied to its QC record.
