Car cover getting shredded by the wind? No matter what you tie it to, it only delays the inevitable? Yep. Several months ago, I called upon my one remaining gray cell to solve this problem. Y'all seen those 100-ft. spools of 3/8" nylon rope at Wally World? Well, I put a fresh cover on an R-Code intermediate close to the house, so I could watch it. I tied the end of the rope to the right leaf spring shackle and began unwinding it around the car. Two loops around the trunk, two around the roof, two around the hood, more or less evenly spaced. The end of the rope tied off around the right side fender support strut. So now the car is spiral wound, like the notebooks.
The idea here is to inhibit aggressive air movement from billowing the fabric and fatiguing it. It now would have to "expand" the rope spiral, which ain't gonna happen. Since you are not using the plastic eyelets in the cover, it will not stress or rip there.
I've watched this setup in action when there have been fairly blustery days. Fabric movement is very minimal. At one point one of the roof spirals fell forward onto the windshield. Inspection showed that the rope as a whole had stretched a little bit, so I rewound it, and it has been fine since.
The only caveat here is the long-term integrity of the El Cheapo nylon rope I used. I have another length of it that has been outside for over two years, and it is beginning to look brittle. You guys know where I live. I imagine that higher-quality UV-resistant material would be better here; I just need to track it down.
Anyways, I thought I'd pass this on if it helps anybody. I was going to put this into the other FE Forum, but Ballinger's avatar pic looks like it was taken two days after he died, and it scares me. If any of you are braver, be my guest.
