I upsized the Camry's 15s to 17s from a Lexus SC, a perfect fit...
...not exactly a different OEM, but the brand of wheels, Fondmetal of Italy, is not a supplier to Toyo/Lexus, but is to Euro companies, Porsche, Audi, Merc and Formula 1 racing teams....so they make wheels TO FIT (vs. universal bolt hole patterns, etc) without spacers and hub adapters. I like that.
