Nice one, making things happen. Bilstein (specifically the ones you've bought, not sure about the other 6 variants!) are a sure thing. Don't think I've ever read someone saying they don't like them.
Eibach, Tein S-tech, H&R (all progressive) I believe only offer one spring option that generally lowers a fair amount 25mm-40mm and may be perfectly suitable. King (progressive) offer multiple options starting at stock and going down to ridiculous amounts. Then there's some other brands that names escape me, that do linear springs which may offer more handling potential at the expense of ride quality, may also be better if you tow. Progressive are the most commonly used. Trawl the forum, there's heaps of info and pictures of vehicles with various springs at various heights. Please do not start a King Springs thread!!!
