you can talk to a guy name Corey around here. He can get great deals on konis and eibachs, IIRC.
There is also the BAT kit, which I have and I love it! Nice even drop all the way around adn handling is great.
The Koni/Eibach combo is popular around here also.
One quick tip, if you get lowering springs PLEASE get new struts when you get the springs. The stock ones don't hold up very well.
Also, try the search feature in the top right corner of your screen. Search the Suspension forum for "springs" "lowering springs" or for any of the prducts I listed and you'll get gobs of results.
Good luck!
