Man, I wish I could help. I am in the same situation as you but trying to decide between the two 2.5" kits. RK is quite a bit cheaper if you look around. I like metal cloak a little more, just havent decided if the extra cost is worth it. In reality I doubt ill ever push either hard enough to notice a difference.
