Question on brake ventilation on Jeeps

[Giovanni]

I found a pretty good deal on set of Black Rhino wheels, now they don't have any holes on them so seems like brakes may get a tad warm. Considering these are wide open in the back, would this make a difference on these trucks?

Not really. The airflow is more backing plate. Look at the color of your rotors. The hotter they are, the darker they are. Rotors that run cool have a light tan/brown color. Hotter ones progressively get darker. Dark rotors are not bad. Mine commonly run a mid brown.
