I've got a spare matching 16" alloy for my Micra Sport + and while it just fits in the spare wheel well (and sticks up about 50mm higher than the boot floor) the existing clamp anchor point in the floor of the wheel well doesn't line up with the centre bore of the wheel. 
I want to invert the wheel so that I can fit a round foam tool holder (which I have already got) in it for the jack, wheel brace etc. To do this I am contemplating removing the existing raised anchor point from the floor, replacing it with a bolt, lined up with the centre of the new wheel, clamped through the wheel well floor, with a large thick washer each side, to give me a point to clamp the spare wheel down to. To compensate for the extra height of the wheel in the boot I intend to cover the boot floor surrounding the wheel with 50mm thick high density upholstery foam then place the boot carpet over top, attaching the carpet to the foam, giving a flat surface again. Has anyone else on here done anything similar to allow the fitting of a full size spare?
