I bought a pre-cut tint kit for my 2011 TC. I got it on Ebay from a company called Blackbox Tint.
I tried to install on one of the back windows and I was lousy at it. I stopped and had a guy in town install, but he used his own tint. So now I have this kit, minus one back window, but the kit also came with two big cut pieces for the steel panels in between the sliding doors and the back doors. I don't know if any TC's have windows there, but that is what I was sent. So you also have the 2 large pieces that you can cut to replace the back window piece I messed up. It was good stuff if I remember correctly, with a lifetime warranty.
If anyone is interested in it, I would be happy to give it to someone for like $20 and the actual shipping cost. It comes in a mailing tube. Just thought I'd ask.
Here is a link to their site showing the precut pieces: http://theblackboxtint.com/index.php?main_page=automotive_precut_kits
