^ Calipers are NOT rotating mass but they are unsprung weight which effects suspension performance.

Physics 101…  
Light tires = best  
Light wheels = great  
Light rotors = very good  
Light calipers = good  
In other words, the less mass you have on the bigger diameter the better.  
Or, try to keep as much mass near center as possible.

I just mounted new tires on the Xterra and I couldn’t beleive how much they weighed.  
I am used to little low profile tires.  
All I could think is how much torque these big tires rob.  
Imagine a monster truck tire!!!
