I can verify 3 months from recent experience... also, these are good wheels for the money, but folks need to understand that the company is not great on finish... as I'm sure a few folks on this forum can verify, don't expect perfect color matching
Forgestar will tell you that themselves if you call them! but if you're willing to wait or find the right set at a distributor, you do get an affordable light weight wheel that looks pretty good!
