You could remove the rear inners if you had a black Jeep as the base back is black for example, in the front you want something in there otherwise youll have a lot of crud and crap inside your engine bay.There might be a couple of electrical connections in there you may want to protect.
Have you removed your factory fenders already ? I think i know what you mean in the front or rear been those the inners are hooked to the factory fenders and they're pain to remove.
With Aftermarket fenders you can keep your inners if you cut them and they're super easy to remove when needed.
Front or rear are now super easy to remove for me, you can see fronts are held at the top by 3 points and factory hardware and couple of tie wraps.
