I would suggest if money is an issue but you want the car lowered, Just stick with A Lowering Spring.
Ebay, Non-brand Name, Brand Name... Any of those are better then Cheap Coilovers.

Here, http://search.ebay.com/search/search...ngs&category0= There's plenty of choices for under $100 shipped.

If you need physical help or just advice on this topic, PM me.
I've been doing this since '98 and have lowered over 250+ vehicles
