I need some recommendations on stiffer springs for the rear of the car. With all the weight in the back it's a lot lower than the front. Thanks guys.

LTuned and Eibachs are more than likely your best best. Of course, you'll need to change out your struts as well. Again LTuned or Bilsteins.

Although, you might as well change the fronts too. I'd imagine just changing the rears would make the handling quite squirrely.

PM Steve Ganz / supratrd for some prices.

BTW, what are you carrying back there? Bodies or stereo equipment?

Carrying 6 12's and the amps, etc.

How much will replacing the springs and struts effect the ride and handling. I suggested we lower the car (just put more of a drop in the front), but he doesn't want to sacrifice the smooth ride.

The LTuned S&S, like the Eibach/Bilstein setups are I think about 1.5 drop all alround, but still very comfy riding. Try a Search on LTuned; there has been plenty of discussion of satisfied customers.

I happen to believe the H&R's are the best spring in the market. But they're 1.4" in the front, and 1.3" in the rear. They do give a little in time. its like they lag...I decided to get them for one reason, I dont feel the difference from stock, just my 2cents.

You got 6 12's in the back??? Damn girl...... You got any pics of the setup?? Also with you problem there is always a height difference from the rear and the front but now I can't even imagine what your GS looks like... Geez.... Just my opinion but with all that wieght back there your going to have this problem nomatter what you do, enless you get yourself a set of coilovers. But then you are really going to compromise the ride quality...
