I just bought an s13 blacktop sr20det and wanted to swap it into this s13 I have had for awhile and never found a full answer on this type of topic but on both sides of the frame rails in the rear are bent upwards on one side it does not seem too bad but the right side of the car is bad enough to have dented the floor of the car in ever so slightly but you can feel it with your foot. I was wondering if this is a bad enough problem to say get rid of the car and hopefully find a shell or if it isn't to be too concerned about.

The car needs an alignment so when I drive on any road that isn't completely flat it slightly pulls side to side sometimes but in a straight it will drive straight but will start pulling to the right if the wheel is centered. The kick-ups or whatever in the rear also seem to be mostly flat with some bangs but not pushed up like the area in front. Also no rust on frame rails if that matters lol.

The alignment machine should tell you if it's bent badly enough to matter. If the thrust angle is out significantly and can't be corrected, the problem is likely in the frame.

Alright makes sense I was planning on taking it in for one anyways looking at the front struts the camber plates are slightly different in the amount of camber on each side so that's hopefully why it rides pulls to the right or worst case they're adjusted differently to compensate for those bends.

Eh, I've seen worse haha. You could weld a straight section in and make a truss out of it haha.

That section is made out of very light gauge sheet metal. You could probably get it straightened/pulled with a stud welder and puller.

I cut both of those sections out of my car and welded in 1/8" box steel, cut to contour so the bottom was level. It stiffened the car up a lot. Now I can put a jack under one side and lift the car and both wheels come off the ground at the same time.

I've got pics of the car sitting on three jackstands, two rears and only one front, without any sag (but can't post here because they aren't hosted.)

NICO actually hosts photos now.

Select the picture you want, and then once it uploads, click "place inline".
Here's one I had kicking around on my computer of some of Greg's cars a while back:
