This article shows that it works with 2009 Scion tC. And it is. with modification. The stock nuts on stock TC wheels will not fully tighten/lock on these adapters because the adapter bolts are too long. To tighten the nuts, the bolts on the adapter must be sharpened. It didn't take a lot of grinding to get this working but if I didn't have the tools it would be frustrating as it shows it works with the car.
