Hi Patrick. No problem! I think you'll really love this setup. I continue to be amazed at the difference every time I drive it.
As for wheels, anything with a 5" backspacing or less will work. I have the Method Standard Race wheels, and General Red Letter tires. Here's the link to where I got 'em: Method Race Wheel Flat Black & Machined 17 x 8.5 6-135 04-Pres F150 | Outlaw Raptor
Hope that helps! Keep me/us posted on what you decide to do.
