View Full Version : Eibach springs in sedan?

Eibach's website shows the sedan springs are still in development. And gm parts websites show the same part number for sedan/coupe springs. Anyone tried the eibach lowering springs on a sedan yet?

I'll be trying them on a V Wagon in the next couple of weeks.

Not if I get mine first ;) I think the Vagon with its lines will look killer dropped.

Well I have the springs, and I'm picking the Vagon up today. I'm not sure when I'll get a chance to install them though. I am on call this week, and the storms coming through Arkansas just won't seem to stop! :bonkers:

id like to get these on my sedan...but i heard there is no hardware for the mag susp. Are you just using the stock ones and does it affect the Tour/Sport changes?

Just use the stock rods. You can still change from touring to sport.

Over time, if not using some sort of suspesnion rods you might get a "service suspension" message light on the Driver Infomation Center (DIC). The rods act as suspension limiters so the Magnetic Ride computer doesn't sense a decrease and then failure to rebound to specific preset height, thinking there is a servie issue of he suspension.

I called Eibach and was told the sedan springs are still in development. They are in need of a Sedan in the Corona, California area to complete the testing.

They are going to have my sedan in the beginning of may for measurements/testing. So hopefully shortley after that they will have a kit available :)

They are also looking for a non v coupe if anyone knows one in the area.

not sure i understand why they need a sedan...should work on both..GM stock parts are the same and D3 ones are too i think.

Gm part numbers for the rear are not the same. Fronts are the same. I think the difference is spring rate for the different weights of the cars.

The rear weight difference between a coupe, sedan, and wagon is less than an average males weight. Factor in the weight of a 1/2 and full tank of gas, and there is minimal difference in all of them.

I don't know what else would be different. Maybe height? Or the shape of the perch?

D3 only sells one set of springs, and they work fine for both coupe and sedan. I've installed springs on both and the setups are identical. Spring rates etc I don't know, but as stated above, the weight difference is negligible.

Looks like Eibach has the springs for the sedan now. #38141.140 .6" drop in front and 1.1" in rear vs .9" front drop on coupe springs. I'm thinking about ordering a set and going to the RE-11 265 & 305 tire combo.

.6 in the front and 1.1 in the rear isn't going to look right IMO... you'll have that saggy bottom look. i went with the d3 comps and have been happy thus far... .75 f and 1 r drop with mag ride adjusters
