Opinions on rear spring idea

I swapped in a pair of jy hvy duty shocks with the coil springs on them.I guess thier called overload shocks or something. They brought the rear of my Dart up about an inch or so and also helped the handling. If your really on a budget this is the way I would go.
Nice tip but the problem I have is the car has dual exhaust & the right tailpipe is too close to the shock (the duals where on the car when I got it). If I can just level the car out it'll give the clearance on the shock to keep the rattle down
