Hello all. I want to change the rims on my 2014 GT to a 19" wheel. I get the car this Monday but the stock wheels have to go, not a fan. What is the widest wheel/tire size I can get without problems or further modifications? I was thinking of just getting the Brembo wheels or a set of Shelby wheels if the price was right? The color of the car is gray metallic. Thanks in advance for any help or pics of your car!!!! Also want to lower it about an inch.
