I was looking in my trunk and considering getting a full size spare, which I measured and would fit, but the problem is, if you look towards the bottom of the hole on the sides, there are posts that stick out and some of them are a bolt with a nut connected to it. Does anyone know what these are holding up (if anything at all), or could I cut them off. My 2000 A6 has the same space for the spare, but does not have those bolts and bars sticking out.
