The stop plate will have less flex but you honestly wont notice any difference , up front is pretty solid as it is . The center diff mount is cool, it allows you to run your carb straighter , but you can also just Dremel the stock mount . The split mount also does what the name says, the diff mount splits in half (from top to bottom) and allows for quicker diff removal . If the mount was cheaper I would of got one , but for 60$ I would rather spend that on fuel, tires, plugs etc
