I tried putting some Velcro tape on the soft-top bag to make it stick in place in the trunk. (Worried that sliding the soft-top around will bash in the exposed tail light fixtures)
It looked okay, but I soon found that the trunk 'carpet' is not really held down at all, so it came loose and just wrinkled up to allow the top to move around. Not secure at all.
So... maybe stick down the carpet with a bit more firm adhesive or screws?
What I'd like to do is screw down two velcro 'strap's, so they're anchored in something solid. Then placing the soft-top in the trunk just requires a quick tug on the straps to secure the top in place.
I'd still like to see some kind of protection for the rear lighting. Ideally, a hard 'shell' cover over the whole rear that has a 'slot' sized perfectly for the soft-top. That would leave the rest of the trunk free for stuff while keeping the soft top fixed and protecting the lights. Shinoo?
No carbon fiber needed, just blow-poly or molded plastic..
