I had one of my employees clock over 115k on his 2018 before he traded it in on a Mach 1 last year. And according to him it had never had a issue anywhere on the car. mind you his was all Cali freeway driving.
I would try some WD-40. I have done it on my truck that has some satin black vinyl strips. Cant hurt it unless you scrub the heck out of it. Just don't get it under the edges because it will soften the glue
Here is mine. But please note that I have a .25" Steeda spring spacer on the rear to give the car a little rake. Also the car will settle after a week or so.
First of all OUCH!!!!! 2nd, I do understand, at 67 I cant move without getting bruises, cuts and scrapes by doing the simplest things, 3rd, it does beat the alternative. So I truly hope you get better soon and that this is the end of your woes for a long long time.

If you are cording the outside of the tire with a 1.8deg Camber then you have too much toe in. Or you are really hitting the turns hard all the time. Get the alignment done correct ( 1.5 deg Camber with 0 deg toe.) Then start playing with the swaybars. This is what I have mine set up. FP track...
