Sourcing services / comparison scope
Turn a wheel reference into a neutral brief for factories. Keep hard fitment constraints, acceptable construction changes and commercial exclusions on separate lines.
Ask factories to quote the same vehicle and brake configuration, wheel diameter and width, PCD, offset, center bore, fastener seat and load rating. The response should show the part number and drawing revision and identify each proposed deviation, including a spacer, altered finish or different fastener.
Set the lot size in wheels and record the delivery ZIP code and date. Ask whether cartons, caps, hardware, tooling, samples and inspection are included. Have suppliers state currency, quote validity, freight assumptions and where risk transfers. Add the missing costs only after the bidder identifies who pays them.
Review the three alloy wheel constructions before fixing the manufacturing method in your request.
Yes, if the quote names the change and carries evidence for the proposed part. A cast proposal might meet the duty at a lower tooling or unit cost, while a forged proposal might better meet a specified mass target. Compare measured part weight and documented duty before deciding.
It is a starting point. Obtain the proposed part drawing, including its mating surfaces and dimensions, then have your fitment reviewer check the brake envelope and lug-seat design for the actual vehicle. Hold substitutions open until the reviewer signs off.
Before
A photograph can convey spoke style. It leaves the factory to assume center bore, fasteners, packaging and destination, so the first unit price can omit key costs.
After
Attach the buyer’s dimension list to every request, number the open fitment questions and ask for separate line items for samples, tooling and freight. Compare like-for-like offers after marking exceptions.
Use the guided inquiry if you need to gather details in stages.
