Just for fun - I put the stock skids back on my 4R and the red line is a leveling laser set just under 11 inches (it was on a small paint can that was as close as I could get to the right height to show clearance. You can see where the minimum clearance is. My 4R in this picture is stock rear spring height and front is set around +1.5" with adjustable coilovers. It's roughly 21" wheel center to fender lip. Stock was around 19.25" IIRC. It's as low as the adjuster ring goes on Fox Factory 2.5 coilovers.
Tires are 275/60/20 - that translates to about 33" height - they're roughly 1.5" taller than a stock 265/70/17, 1/2" taller side by side compared to a 285/70/17 Toyo AT, and 1" shorter than my 285/75/17 Cooper AT3 set. So compared to a stock 4Runner - clearance up front on mine is around 2.5-2.75" higher than how I got it. You can't see it in the picture, but the rear diff is the lowest point at around 10". The second lowest point is the transfer case skid plate (aftermarket) and the third lowest point is the rear most IFS cross member. It's lower than the KDSS portion of the front skid plate by around 3/4".
