got some industrial strength velcro that had self adhesive and finally did wheel covers and got that Kammback on. is entirely velcro (lips go in to trunk crack though). been up to 60 w/o issue. will put a failsafe on with a rope on spoiler so I kill my paint and not some tailgater. but happy with result. wheel covers, have to warn a bit on this one as it puts an airgap (with the junky style wheel covers I have that are held on with the wheel nuts). guessing catches at least some air/turbulance.
need to do a few more things but did a cardboard piece over windshield wipers and that seems to be ok. anybody try something like this? advice?
