Have a 2016 1.3 S CVT and just gunk supplied despite fittings for a spare. Always like a spare as nails dont usually puncture in the approved position. Have fitted a space saver but to get the Honda foam insert is silly price. Have supported the flimsy floor with plywood and wood supports using space saver as support. As this cuts down space for Jack, foot pump etc. I am looking at making plywood sheet to place on top of the boot floor, similar shape to rubber boot mat. Estimate this will give plenty of strength for luggage support, give loads of room under floor and round spare. Might even leave gunk and compressor in as double back up. Aim to varnish board to seal it and then cover in carpet/carpet tiles. Might improve sound proofing. Anyone tried this? If so does it work ok?
