One thing to keep in mind is that "Jacking Rails" don't fall with in the budget of many owners. Or are hard to justify if you don't plan on making use of them often.
I would have never thought that "jacking rails" would have found justifiable way into my "tool wants/needs". But after installing a pair on my 2017 Ecoboost Mustang, I transferred them on to my 2018 GT. I used them much more often than I would have ever thought.
Before the "jacking rails" I did look at the great number of "jacking pucks" available. My answer was to use my floor jack and fold a few layers of cardboard over then place on the cup of the floor to protect the paint finish, and allow the pinch weld to settle into the cardboard cushion.
For what it's worth, even after installing the "jacking rails" I still use at least two layers of cardboard to protect the finish of the "rails".
The above is what I have personally used in the past with great results, however your results and experiences my vary. Doesn't matter what method you use, if you don't use your brain and common sense then all bets are off.
