Don't remember any extra pieces you could add. I know that there was an update that had new side covers and insulation under the gas tank. One of the fixes for over heating was to flush the cooling system and put ice antifreeze in them. That helped in the cooling dept. I have not had an issue with any of my grizzlies over heating, but I don't ride in the mud or streams.
