Front and rear are half an inch apart in width but thirteen millimetres apart in offset. ET27 at the front puts most of the barrel outboard of the mounting face while ET40 pulls the rear back inboard, so the two faces sit at noticeably different depths and each needs its own machining programme rather than one shared setup with a wider rear — and they still have to read as a matched pair once the car is on the ground. Gloss black over an open web face compounds it: every internal window edge takes paint, and gloss shows a thin spot or a build-up straight away.

That is the part of this build worth talking about. The specification itself is straightforward: 20×8.0, 5×112对, ET27, 66.6 mm bore, Gloss Black.
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 690 kg.
Every set ships with a serial engraved with size, offset, centre bore and load rating, tied to its QC record.
