Since nobody beat me to it, here are images showing the height from the roof to the top of the factory rack at the front, middle, and rear roof mounts. Hopefully I got the tape measure against the roof as I didn't get up on something to make sure when I took the photos. It looks like the ARB rack ends up adding a couple of inches of extra height. But it's somewhat tough to come up with how the numbers compare because the real question is what is the height at the highest point of the vehicle with the factory rack versus the ARB rack. Assuming the ARB rack sits level, it will be relatively easy to get the number for the ARB rack. But it's tougher with the factory rack and when an extra inch is the difference between having clearance and damaging something, the numbers obviously matter. If measuring from the ground, the measurements need to be done on the same vehicle because tire size and suspension will affect the overall height.
My clearance limitation is where the bottom of the garage door ends up when it's fully open as that's the low point I'm up against.
Either way, I still feel that ARB made the correct decision to go with one rack mount that fits all 200 series LC's.
