hey guys i found a great place for buying factory wheels. You can get wheels from other cars for very cheap. The first website is cheaper.
For example the 370z rims that I have can be purchased for $370 instead of dealership price of $950
Or you can get the stock rims for cheaper....

except this website thinks the 2005 - 2013 Scion tc wheels/tires are the same size.

 

Let's see some more pics of those 370 wheels on your tc! That looks great!
