The springs i got from speedwaymotors.com 0675.500.1000 - EIBACH PROGRESSIVE PULL BAR SPRING, 6-3/4" rate 600lbs
http://www.speedwaymotors.com/Eibach...rings,271.html But you'll need to get perches for the springs as they will be too short to run on their own the perches I got from daymotorsports I can't think of the part number off the top of my head right now.... but they are adj perches the spring set me back 126 bucks that includes shipping I just got them today actually. I ordered them on sat and shipped it ground.
Shipping might be a bit more for you since your overseas but these are the springs I'm running in the rear you'll need perches tho. Also some Ford E150 rear shocks will keep everything in place when the car is jacked up
