Thank You!
Congrats on the upgrades, you'll enjoy them.

Between the lift and the larger circumference your ride height has been raised about 3 inches.

I don't think it's necessary to adjust your headlights.

Your speedo will be reading 3 1/2 - 4mph slow. meaning when it's reading 60 - you will actually be doing around 64.

I have the same set-up as you (different brand of tires - TOYO A/T's; but the same size) and I bought a superchips F5 3874 Flaspaq programmer to adjust the speedo for the larger tire size.

Before I adjusted the speedometer, I used my GPS as my speedometer, that's how I was able to tell how far off my speedometer was after putting the larger tires on.
