I can second this.  I let my car sit in the sun awhile when I installed the top this Fall and had my bow adjusters turned out about 1/4 to 3/8 inch to tighten the fabric.  When I noticed later it was pulling on the upper part of my windshield frame I screwed the adjusters back to 0 which left a bit of slack in the top - I could push it up above the bow an 1/8 inch without any effort.  I checked it today and the top seems just as tight on top n0w as before.
