I was wondering if you could give me the exact tire and wheel size you used on the truck in your video. It was the black 2013 Ford f-150 at your Cleveland Ohio location. I know in your video it stated that you used 20" pro comp wheels, and 35" pro comp tires, but that is all it said. I would greatly appreciate it if you could give me that information. Thank You!

Its my understanding that there are some cutting and drilling required with the installation of this kit. If that is true. Could you please tell me where exactly on my truck, and how much cutting I would have to do. Secondly, Do I need a cutting torch to make these cuts, or can I use a grinder. What would you recommend. And lastly, Can the average do it yourselfer install this kit at home in his driveway with basic tools.
