Requirements review
Buyer supplies vehicle year/make/model, engine and transmission codes, OE reference for identification only, tooth count, diameter, inertia intent, clutch installation face, quantity, US destination state and drawings when available. A family brochure is not a drawing for the offered part.
Supplier questions
Ask aftermarket flywheel manufacturers for the exact reference, dual-mass versus single-mass construction, included bolts, balance method statement, sample availability and packing unit. Unverified interchange claims stay pending.
Quote comparison
Separate per-piece price, bolt kits, freight, taxes and service fees. Clutch discs or release bearings that the buyer will source elsewhere are not inside a flywheel-only quote. Do not treat a shorter number as a saving percentage against an unnamed market.
Order handoff
Record the accepted sample decision, remaining interface questions, Incoterms and who receives the shipment at the destination ZIP. Batch balance documentation requested from the supplier is not a blanket approval of later lots.
