2012 TC wheels on a 2007 TC?
 

I have an 07' tc. Planning to add 2012 TC wheels. I'm going to need spacers with a pcd conversion kit (5x100-5x114.3). I found some 15mm spacers with built in studs. Do the factory 2012 wheels have a cavity in the back for the stock studs to sit in?

My 2014 rims do not. not 100% sure about 11-13 but I doubt it.

Sorry, but I was mistaken in my last post. My 2014 stock rims DO have the cavity for the studs to sit if you were to use spacers. Still not 100% on the older 6 spoke rims.

The stock 11-13 wheels have the cavities you need. 12s will work just fine.
