The 4/4 Sport isn't designed for a spare wheel and to my knowledge the only way you can carry a spare is on a luggage rack but then you lose the carrying capacity of that.
Roger is right. I have got a luggage rack and the spare wheel can be fixd to that frame. As luggage capacity is more important to me the spare wheel always rests in the garage.
The 4/4Sport does not have a car jack nor a tool tray in the original setting.
