Something to check. Not sure if I'm some sort of anomaly, but...
I installed the Genesis dual battery kit in my JLUR this past weekend. Fist off, I'll say the coilovers make it a pain in the ass as the brackets prevent the battery tray from sliding out the way the install video shows. The housing for the small Stop/Start battery nests right up next to the bracket, eliminating the wiggle room needed to get the tray out. It may be possible to drop the small battery out the bottom of the fender first, but I decided to just cut the tray in half instead. Anyways, the real reason for the post:
After removing the battery tray, I discovered that the head of the front passenger coilover has been rubbing against the bottom of the sheet metal support for the battery tray:
I decided that rather than let it keep rubbing and possibly cause popping noises while articulating, I'd notch it out to give it some room to move. That's when I discovered just how much it had been rubbing!
I emailed these pictures to Andrew over at EVO a week ago, but haven't received a response. I'm assuming I don't need to be concerned about the damage as there's a lot of meat on these shock heads, but I'd still be curious to know if this issue has been addressed seeing as I have one of the earlier production kits. Probably worth checking yours, I had no idea this was going on. It wasn't making any unusual noise (aside from the typical coilover type noises) so I'm guessing its just been slowly wearing down over the past year.
