Pro tip: only base armor rating matters with that perk, meaning you can't boost it through tempering. Daedric gauntlets have the highest at 18. Additionally, Khajiit actually do 10 damage on top of the 12 damage from their claws as a result of being a "beast" race. Therefore, they do 22 damage at the start and at most 40 with the perk. Without exploits or mods, you can boost damage by 86 points through enchantments for 126 damage total.
