Review timing
Include your target decision date and the quantity per configuration. Supplier minimums, sample readiness and delivery estimates are confirmed for the quoted SKU after specification review.
Written RFQ
Send the starting specification
For wheels, include rim diameter and width, PCD, ET, center bore, load rating, finish and vehicle. For tire requests, add size, load index, speed rating, operating conditions and tread pattern. For hub and bearing projects, give the OE cross reference or VIN, flange dimensions, ABS encoder, seal and the included hardware. State bore, outer diameter and width for a serviceable bearing. For accessory requests, give the thread or interface dimensions, material, finish and pack quantity.
Compare an existing design and a custom run on the same fitment. An existing design can avoid new tooling when the supplier confirms the required size and finish. A custom run can address a different brake envelope but adds drawing and sample approval. For a concrete brief, write rim diameter and rim width in inches, ET and center bore in millimeters, and the load rating with its unit. Treat any value copied from a catalog as provisional until the supplier ties it to the quoted part.
