It goes against conventional methods that normally work well. The passenger side tire is the normal side tire that could use a little weight above/behind it.
This should not have to be. I am having an issue right now and something has been suggested to me. If needed, there is probably enough rust in between the rear mounted battery and the engine to not allow a good ground. Having done a battery relocation kit before, there was no issue. Did it this time on the current car, I’m like WTH?
