HelloWell it is very important what rear springs have come with order under this common order number E1528-140, I did my homework when ordering mine and found this pieceof info -
Ausführungsbezeichnungen:
Fahrzeugzuordnung:
Vorderachsfeder:
EW 1515101 VA
4-Zylinder
Vorderachsfeder:
EW 1515001 VA
5- und 6-Zylinder, S4 mit Klima
Vorderachsfeder:
EW 1527001 VA
5- und 6-Zylinder,
S4 mit Automatik und/oder Klima,
S6 4,2L
Hinterachsfeder :
EW 1516002 HA
alle außer Avant
Hinterachsfeder :
EW 1521002 HA
nur Avant
In short there are 3 types of FRONT springs , and 2 types of REAR springs , all under the same order number
In shortER

are the corect part numbers of the springs to be used on a sedan . ( and YES I did have to reposition rear perches - chose not to do grooves on the shocks but made 15mm spacers , bear in mind that as you raise the rear , there is more load on the front and it drops a little so it is not that bad. As for ride and handling , I am satisfied for a road daily car)
pls see attached file where spring size, ttl height etc are outlined.
On same deal planning to change springs, these are correct right ? Hope you guys are still active hehe.

I would use correct springs for 4 cyl or 6 cyl at most as S6 engines are much heavier and springs are diferent. I am not sure what will hapen, but apart from coilovers - only correct for model - Eibach springs have worked for me. If you want lower and more sporty ride , Bilstein B8 is the way to go on the same spring ... My car is on B6 but as I mentioned it is a daily, so I prefer softer but tighter ride.

had previously v6 2.8 AAH engine, now its 1.8t AEB, so the weight different is not that much. Id like to have it even or front is lower then back, right now its reversed, back more low and the front is up - so the eibach setup should do the trick then ?

As C4 are front end heavy , what Eibch has done is lowered the back in order to transfer weight to the rear and reduce understeer. The way to correct it for good look purposes is to raise the back by instaling a perch on the rear shocks, on bilsteins there is a groove and a ring that fixes the srping holder plate. in my case it was 15mm if I remember corectly and bear in mind that it is not a direct ratio - 15mm perch may or may not raise the rear by 15mm, so it is a bit of trial and error. rear geometry and condition of bushes, etc also plays a role in rear end height.Comment

Also, try this, grab the car by the boot and try and raise the rear by hand 1 cm and see how much weight will transfer to the front
