I think you're better off changing the bumper itself to an offroad version which is half the size, to give a better approach angle. The skid plate is still going to get caught on the ground when off roading and place significant force on the front end, and limit your maneuverability.
I had the stock Platinum bumper on my Y62:
Broke it virtually in half during an off road session, and had it replaced with this fiber glass version bought in Sharjah, including the LED light, painting and installation, for just under 2,000 AED:
But today I was searching for a new body kit, and found a shop in Dubai called Samurai - Eagle, that apparently import their kits directly from Japan. The design looks amazing, but I'm struggling to pull the trigger because of the price. (10k AED for front & rear bumper and diffuser, including paint and installation).
