      Do I need to adjust the wheels in anyway? I have stock wheels and tires (2018 Ecoboost premium performance package).

      • With stock wheels the would be tucked very far under the flares from this kit. People will run wider aftermarket wheels with an offset and backspacing to achieve a flush fitment.

      To complete the look of the body kit, where could you find the same headlight covers that make it different colors?

      What would be the lowest offset that you can run on your wheels before you run into rubbing on the front fenders

      • This will depend on tire size, wheel width, and suspension height.
