Thanks for the info guys!!

The other option is the Ghetto way to do it, Compress the spring and heat with a torch... you will lose ride quality and if done wrong will not level. I heard a long time ago that a set of STS springs from Eibach would lower it but they discontinued.. you might get lucky and find a set floating around.

The STS Eibach springs technically would have worked, I got a set of Eibach DTS springs that are better fitted (the part numbers were different) I even believe there was a set of Lucerne springs back around 06 Eibach Made. Any of the Eibach kits are almost impossible to find, and i believe My Car is the only Bonneville Running Eibachs

The Eibachs DTS are the only ones that work. The STS springs don't really lower the car, I had a set and tried them years ago. Pat was the only one successfully able to do it. I have been searching ebay and craigslist for years hoping to find another set.

I was scouring Rock Auto to see if there were any other GM cars that might have a different set of parameters that would work, but it seems that the ones I found were either way too weak, didn't have a double pigtail end, or were too tall or the ID was too far off. I even looked at different manufacturers and came up empty ( ford, Dodge, BMW etc ) I'd really like to lower the front a little, the wheel well arc to top of the wheel is big enough for me to stand a fist between...that's pretty excessive IMHO, and a larger Rim isn't going to fill it out enough without looking ridiculous.

How much ride height did the Eibachs drop? I was figuring about an inch and a half to 2 inches up front would be ideal for daily use.

2" is a lot when talking in Terms of suspension.

Here is my car next to a stock 2004 SLE.







I have since dropped the rear a little more with adjusting the ride height with the Tech 2

Well, there's 3 1/2" distance from the top of my tire to the top of the fender lip, so somewhere around 1 1/2" would probably be enough to avoid any issues with suspension bounce while turning....

You can always make a set of coil overs for the front and rear....you can buy all the parts separately now days and make a set.. might take a bit of trial and error but not impossible.
