They look good! We are hoping to update our 2007 GT conv with a 2016 GT conv around April if all goes well. We were a little disappointed to hear that the Foundry wheels for 2016 now have black painted inserts. My wife had her heart set on the Magnetic inserts. She liked the idea of the inserts matching the color of the car.
I bought a set of 2015 take offs like you but I had problems with the wheel bore. It was a .2mm difference so I had to shave some off. How did you solve this problem? Or did you run into it?
