Hi Guys, 
  
After all reading and understanding about how to lift my car, I decided to do it by my self. 
My car : 2006 Impreza SW, 2.0L, 4WD (euro model). 
I took my measurements from front and rear strut mounts and they are precise and fit my car perfectly. 
  
The spacers fabricated from 6061 Aluminium. 
Attached my drawing in PDF. I also have it in X_T and Solidworks but I cant share it here. 
  
Enjoy, 
Arik
