I finally got the GT350 wheels mounted up on the 2021 GT500 using a hub-centric spacer from CJ Pony Parts. This will help in many ways as they are a 19-inch wheel so I will have more sidewall than the factory 20-inch wheels, I also am not nervous about having tires installed on these as I am with the factory carbon fiber wheels. While I am waiting for my Mickey Thompson ET Streets to arrive I decided to take the 2021 GT500 back to the drag strip to see if we could improve on our times from the factory tires.
