Nissan 370Z Forum - Rocker panel indentations?

Posted this in the exterior/interior forum, but figured this might be a better place to get some clarification.

I was working on the 370 and noticed something on the rocker panels. It looks like there is the slightest deformation on each rocker panel towards the front of the car, almost under where the Z turn signal is. The best way to put it is that it looks like a very slight, large dent in the panel surface. Can only really be seen by getting down on the ground and looking down along the sides of the rocker panels from back to front.

I'm not sure if this is from mounting points on the rocker panels pulling the plastic a bit, or a botched job of putting the car up on a lift, but was curious to see if anyone notices the same thing on their car.

It's on each rocker panel in the same spot, so I'm leaning towards it just being a factory thing but wanted to check with anyone else to get their opinion. There is no damage to the paint where the indentations are. I did just have springs installed, but noticed this issue beforehand so it was either done at the dealership or came from the factory like that.

Thanks for any help.

p.s. - attached some images of the area in question. You can't see the spot in the images, but wanted to include them for reference.
