hey guys, i'm still new to car modding but am interested in adding coilovers to my car also

here are a few sites i've come across which sell buddy club N+ for a reasonable price:
http://www.wirednj.com/
http://lsdmotorsports.com/

has anyone purchased from these sites?

i've got a 2004 cl9 lux, which specific model of the buddy club should i be looking at?
help appreciated
thanks
