On my elise there were turnbuckle cable adjusters in the middle of the roof front & back that let you tighten or slacken the cables.
You just need to open the access flap in the headlining to get to them. Dead easy to do. I had to tighten mine on the drive home from the dealer when brand new as at 70mph I had a gap big enough to put my hand through between the top of the screen & the hood.
