Bring the essential wheel dimensions and project constraints together before requesting a quote.

A complete starting brief allows the team to identify missing information, compare the mounting interface and agree on the next evidence required. Values should come from the actual vehicle or controlled drawing whenever possible.
Provide diameter, width, PCD, offset, center bore and mounting seat. Include the brake envelope and available clearances.
Identify the vehicle platform, year or VIN, axle load, intended duty and any changes to brakes or suspension.
State quantity, target market, timing, finish preference and the documents or validation evidence needed.
Use these stages to organize the brief; they indicate a sequence, not project completion or measured performance.
Record the actual configuration and any modifications affecting fitment.
Include units, tolerances and a drawing revision where available.
List the required inspection, tests and market-specific documentation for review.
System certificates, product approvals and test reports have different scopes. Ask for the specific documentation applicable to the selected configuration; no certificate is implied by this checklist.
Share the information available now and identify anything that still needs confirmation.
