i just thought of this one....

what spring rate does the Deville have stock?? FE1...FE2... That would be very important to know for someone like me who already has FE2 Stock and not loose the ride

because Eibach may have designed the springs around a particular spring rate, just in a lower heigth

Thats most likely what they did. I don't really think that the Deville'* really had a sport suspension lineup. As you said, they found a common spring rate, and most likely reproduced it around that.

Well... I know that the Eibachs are only rated at a 1" drop, which is fine, but unsure as to how much it'll drop the rear.

But, I betcha these will drop the car: http://www.gripmotorsports.com/pi~pn...ings-7365.html

ok then what we need to do is Contact Eibach and see what the size of the coils are....and if they had a specific spring rate in mind when doing these springs

also we need someone that has Some Caddy friends, OR a cool dealer that will let us check out suspension codes.....

I would assume that the DTS has the best suspension combo....

I'm gonna doubt that Eibach will give away the spring rate info. I've tried contacting them before, but they don't seem to want to give too much info, other than what they can read off of their own screen. I'll shoot them an email though.

I'm sure if you go to a parts counter at a dealership, they might give you the info, if it'* on their screen.

Well, I just called.

He doesn't have the exact spring rate, but the info he does have" 15-20% increase over the stock spring rate, and they are Progressive springs". Progressive meaning they will get stiffer as they are compressed.

IMO, if the Deville'* rear end is a bit heavier than the Bonne'*, I think these will actually give a bit softer ride in the rear than say if they were installed in a Deville. I personally think that there will be a drop, but who knows how much.

I sent GMPD an email asking if they had the spring rates for the two different rear springs.
