Nice Squat..

 

Not as much as you might think. It causes the rear end to "wallow" but not lower that much more than the front does

 

I’ve had 30 , 25 lbs bags of gardening soil in Oldblue with the lowering springs and still didn’t bottom out, or hit the bump stops.

 

That's kind of what I am saying, after years of experience with Chassis parts, builds, etc. I am in Chassis Warranty Analysis at another OEM now, so I see all kinds of stuff. If you can't handle bumps and corner better than most, the modifications aren't really functional. It's your ride. I am not going on a stump over it.


To Old Blue:
Stiffer springs... so, yeah, I can see not much sag.
We have a railroad crossing nearby that the kids used to call "Cedar Point" with Mom in the minivan. When I had real stiff springs on the autocrosser, we would literally got air in the rear over that thing! They loved it! I had adjustable shocks set to soft for daily driving, so it was minimally damped overall... actually gave it kind of a kick up going down the other side.

 

I load mine heavily as well, still OE front springs, but Cobalt SS/TC rear springs, never bottoms out either.
