"Torque creases" or just a dent?

It is roughly a 2.5" long vertical crease almost centered above the rear wheel.
I did some launching last weekend and it was hooking really well with the suspension setup and the aired-down et streets. Very little spinning and made me question if the 10bolt would live to see another day...
Is this a torque crease or did someone just hit me and i didnt notice it til now?
I'll get some better pictures of it soon.
At the bottom is the video of a few of my races from last weekend.
