I bought the 1.7 F / 1.5 R springs from Texas-Speed and had a body shop install them while it was having other repairs done, I've noticed it sitting lower in the rear I think, what's the chance they put the front springs in the rear and vise versa. I never looked at them.
Not to mention every time I cross a not so smooth bridge the rear slams and bottoms out. But not in dips, just bumps etc

 

Correction, it might be 1.3 on the rear.

 

I don't know much about lowering springs (yet), but 1.3" at the back end is less than 1.7" at the front end, so it would be lower by almost half an inch in the back?

 

It's one or the other 1.3/1.5
It's also leaning to the left just a tad when it used to lean to the right. I'm just wondering if the rear springs could fit on the front... If its even possible for them to screw it up like that or not.

 

If it were me, I'd take it back to the place that installed them and have them check it out.
