It appears the spare tire is affixed to a hinge just below the tailgate. Take a close look and you will see bars extending outward just below the tire.

It would be useful if you took long trips and would need a full size spare. But it takes away from the sweet design of the new E70. I would NEVER install it on my car. Looks like a Rav 4 Wanna Be.

Rims are nice but I like my Stock 20" better.

The push bar on the front is fine. No opinion either way. Not sure why you would need it or if it is just for looks.
