Gen1 MS3 Eibach Prokits on a Gen1 MZ3 Drop

Gen1 MS3 Eibach Prokits on a Gen1 sedan MZ3 Drop

Has anyone installed Gen1(07-09) Mazdaspeed Prokits onto a Gen 1 (04-09) Mazda 3 sedan? What was the drop and how does it drive? Pics would be great too.

MS3 Springs I was told by Eibach are progressive for the Prokit, while linear for the MS3. They are also much stiffer starting from 160 going to 240 while the MZ3 are aroung the 160/170 lb mark.

Wow, no takers.....guess no one has installed these on their sedans'. No worries........

Maybe someone with some engineering background can help me figure out whether I'll see a drop if any and how much front to back.

Front what I've scoured through the web...for 06 Sedan 2.3

MZ3 OEM spring rates are 150 front and 130 rear
MS3 OEM is 188 front and 171 rear, gaining a 1/2 increase in front, and no change in rear if installed on MZ3 Hatchback(haven't found anything on MS3 oem's mounted on a sedan)
MZ3 Eibach Prokit (5545.140) Linear Rate are 160 front and 171 rear: advertised 1.4 drop in front, and 1.2 drop in rear.
MS3 Eibach Prokit (5549.140) Progressive Rate is 165/240 front and 148/222 rear: Drop on my stocker ?

So here's where the guessing game begins for me, but possibly not so much for an engineering guru. Any technical input would be greatly appreciated....

Wondering as well if the length of these coils will have any bearing on ride height?
