This question falls into the category of people buying undersized vehicles then believing that by adding components i.e. dual wheels, air bags, springs, etc they can build their vehicle to match a equivalent factory unit. Unless you can get the vehicle re-certified to increase the original manufactured specs, the vehicle stays at the original. While you may believe in your “peace of mind” upgrades have accomplished the goal, there is a legal consideration still there. In the unfortunate event something should occur, a decent attorney could go after you for creating an unsafe situation.

Bottom line in my opinion is there is a reason for the door stickers. Use them, don’t scrimp with a “good enough” attitude, and it’s better to have too much then just enough or not enough.
