① Specification intake
Mark the wheel center bore and hub pilot separately. For clip-on weights, provide a rim flange cross section or reference wheel. A vehicle name alone leaves the aftermarket wheel interface open.
How we source
Start with the part you need, the application it must fit and where you intend to sell it. We turn those inputs into a supplier inquiry that keeps dimensions, packaging and commercial terms visible together.

A supplier’s catalog part may avoid a new setup if its drawing and finish match. A custom specification can address a missing size, with its own sample approval, tooling and order quantity.
A single supplier can simplify carton labels and revisions. Separate suppliers can fill different flange profiles, but they must quote on the same pack basis and follow the same acceptance plan.
We coordinate requests and compare document scope to the SKU and market. The selected supplier, laboratory or authority issues the underlying evidence.
A request for clip-on weights by mass leaves flange profile, wheel finish and pack count unstated. Quotes can reflect incompatible clips or different quantities per carton.
A reference flange drawing, mass increments, finish and pack unit give suppliers a common basis. Flag open issues in the quote sheet and compare sample results against agreed checks.
Send a drawing revision, OE reference or measured sample. We can clarify gaps before asking suppliers to quote.
