I am looking for a wheel that will allow installation on a 2017 GT. Would prefer a squared 275 40 tire size, any 19's? or am I forced to move to a 20"?


  • We have many different 19" wheels options. that will allow room to install the big brake upgrade. Use this link to find a set you like !

Will XO Luxury Veronas 20x9 with a 25mm offset clear the calipers? I have the PP 6 piston calipers and have plenty of clearance.


So which is it, 9" or 14.5" rotors for the rear?


  • The Ford Performance GT350R Brake Upgrade Kit, comes with two 15.5-inch cross drilled front brake rotors and two 14.9-inch cross-drilled rear brake rotors.

Hello, I miss more information about wheel clearence (max ET width of the rim and min diameter). Also the other GT350R kit on the market moves the rear approximately 0.27" outwards as a result of changes necessary for parking brake - is it the same with this kit? I currently own Fondmetal STC-45 20x9 39ET(front) 20x10.5 45ET(rear) and I believe I would need a spacer in the front to make this work, right?


Can you post a list of the wheel specs needed for this brake system?


  • The Ford Performance GT350R Brake Upgrade Kit requires aftermarket wheels with a +35mm offset.
