Opinions on rear spring idea

I'm just looking to get the back of the car of the ground it's just a 4 door so I'm not realy looking for the performance just ground & exhaust clearance. The car has dual exhaust but whoever bent the right tailpipe did a poor job and with the rear sagging the pipe is rubbing on the shock. I've adjusted the pipe as much as possible not it still hits but lookimg at where it hits if the back of the car was up higher it would be well away from the shock. The pipes came on the car when I got it & are in too good of shape to replace so I'm looking at the springs for the clearance that I need. I've already had to replace the one shock when I bought the car 6 months ago when I bought it because the pipe had rubbed through it and it's already rubbing into the new one. Here's a pic of the car just want it level or slightly higher on the rear.
