My car sits funny
I used factory 1LE springs to lower my car. As is they really don't do any lowering, so I cut one coil off each front, and almost two coils off the rear springs, but my car was higher in the back to start with. You can still get 1LE front springs from the dealer, but they discontinued the rear ones. I got mine used.
Another option is to buy a set of Eibach's. There're good quaility springs, and even come as OEM on some exotic cars. They're just more expensive than stock is all.
i used to have factory springs and shocks (decarbons) and the car was setting normal like any other f-body, a little lower in the front (rake) which looks good,
then i put LGM hypercoils and bilstien shocks and my front sat a little higher than the rear, so i used spacers to raise the rears, looked good then,
as of now, i removed the lgm hypercoils and put the stock springs back on my car due to having long tubes and scraping on most speed bumps, but i kept the bilstein shocks, and now my car sets a little higher in the front, i thought of cutting a coil or so from the front spring, but i wasn't sure if i wanted to do that.
