NOW we're talking.
I did this 2 years ago.
Eibach " Pro-Kit " springs, NOT " Sportline ".
Combined this with Bilstein Sport shocks.
Amazing.
The ride is firm but comfortable.
The Eibach's are linear springs in the front & progressive rate at the rear.
For springpads I used # 2 up front & # 4 in the rear ( to maintain that slightly raked look ).
Anything else you want to know, just ask me.
