RAYS, GRAMLIGHTS & VOLK RACING Model Number SKU Codes

How to determine size, offset, PCD bolt pattern, and color from Rays Wheels SKUs and how to reverse-engineer them

Rays Wheels uses a 10+ letter SKU that encodes the wheels model in their lineup, the generation of the forging mold, wheel size & offset, and color. This SKU is used by retailers to exactly determine the wheels specification. Some authorized retailers (e.g. Vivid Racing) display the Rays Wheels SKU on their product detail page while others do not.

Decoding the Rays Wheels SKU is useful since it allows us to synthetically re-create SKU numbers that may (or may not) have existed in the past, in lieu of an authoritative source of historical SKU numbers, so we can search for these numbers on eBay or elsewhere, where we may find rare wheels that others may not have found.

The information encoded within the SKU number contains details of the wheels’s model, generation, wheel size, and color.

Each letter in the SKU designates a code:
