Selecting the right springs ?

I have a stock suspension on a 04 gto and I wanna lower it a bit for a more aggressive look. I don't want to slam it. Someone told me eibach PRO springs. So I don't have to change my shocks. To those of you go have aftermarket springs what is your opinion? How low did you go and how is red quality? What else did you change during install like bushings shocks struts ? Thanks guys

I wouldn't run Eibachs with stock struts. Also, if I recall the height of the Eibach rears correctly, you should be running rear camber bushings to correct for the camber with an 1" + drop.

Cause with the eibachs I won't have to change my shocks tho right? What would your set up be? Just want to lower it a bit but make it a smoother ride too. Not bumpier

If you want to get lowering springs in the front, you should use something like KONI or LOVELLS short-bodied struts. Stock style struts are not designed for use with lowering springs because of the reduced suspension travel.

In the rear, it is often said that if you drop 3/4" of an inch or more, you should use camber adjustment bushings to compensate. I am no expert in alignment and suspension geometry so I'd take their word for it. EIBACH drops 1" in the rear.

I am currently on stock height KING Springs front and rear coupled with KONI shocks/struts.

If it were me, I'd look into LOVELLS springs with a slight drop, nothing as drastic as EIBACHs.

Looks like your rear is already sagging. If you want it lower still, you'll be looking at a fairly aggressive drop spring and a modest new drop spring would probably raise the rear.

Not sure how the roads are where you are but I went stock height and am glad I did. Low looks cool but I find myself with my nose over the parking space cement blocks often and if I was lowered, I'd be doing all sorts of damage to my front bumper.

Here's my car with King springs. This is what stock height is supposed to look like:

Oh dang. Your goats clean!! Roads aren't terrible here *sacramento ca. But I don't wanna slam it. Just tuck the tires a little. I know what you mean about parking cement blocks cause I'm trying to already get myself in routine on not pulling up all the way. Just curious on what other gto owners went with suspension wise

Eibachs on the GTO do not have a great reputation. You can go 20mm (3/4") drop without special shocks or camber adjustable bushings. Lovells, Kings or Pedders are the only springs I'd consider. I ran Lovells 20mm drop. My rear camber with plain poly bushings is -1.2*/1.4*, well within stock specs.

How'd did you like the ride quality of your lovells compared to stock

The BC Coilovers will allow you to drop as little or as much as you want correct? I am leaning towards the BC kit because its under a grand and its coil overs, where as the Lovels Eliminator kits are like $1200 from Kollar and they are just a strut shock combo. I'd much rather have coil overs then just a shock strut combo. and BC's are a quality product from what I've researched. Does anyone know the ride quality of the BC's?

I know very well first hand, that modding the suspension harsh-ens ride quality, but I would like the softest of aftermarket set-ups there is, if possible. Does anyone know if the BC's are softer then the eliminator kit or vice versa? Thanks.
