A bit hard to tell what you've got or done Nick because I can only read English and you seem to have written your post in some sort of foreign language but I'll try and help out anyway.
You have an ED right and you have $400 to spend. This will only buy you springs with a bit of change left over to go towards fitting or shocks. I reccomend you get a camber kit as well, K-Mac is probably one of the best around for ~$250. Springs will cost you ~$300 set (4). Shocks - Koni are good but quite expensive, over $400pr for front nearly $300pr for rear. Bilstein are another good shock, a bit cheaper but not rebuildable like Konis. I have a set of front Konis that need rebuild for sale if you are interested, make me an offer. I'm in Canberra.
