This is our 3rd hardtop convertible and we just got around to trying something I read about long ago. To keep the flap out of the back seat belts when the top is down, strap seat belt shoulder pads around them. It works! We put Sheepskin pads on, hubby took the car out, top down, at 120 mph and NO FLAP!
Supposedly, using something with a bumpy or fluffy surface such as sheepskin works best, but we might try a smoother pair with BMW printed on them.
