Here's a pic of Steeda sport springs with 18x10 deep dish.
WITHOUT the adj. Panhard my rear end was off a little more than an 1" and it cornered real bad one way, oversteer...and understeer the other.
Personally, I wouldn't do the springs without the bar and brace and the same time. It is easier to do the bar & brace with the springs out anyhow.
The thing I wish I would NOT have done was the adj. 3rd link. Now that my pinion angle is correct again, I have the dreaded driveshaft klunk that my wife's 2007 GT/CS has had since day one. I think when the pinion was off the shaft was loaded enough to not klunk.
As a comparison though, the SPRINGS ALONE did not cause a harsh ride. It rode great, even on 35 series tires. But the other added rear parts really firmed it up. Not bad, even on crummy Michigan roads, but more firm. I like it actually, and now can get rubber in 3rd, which before it woudn't due because to much energy was lost in the weak factory suspension pieces.
