How much are you looking to lower it? If you dont go too crazy (over 1.5") you may not need a camber kit. I personally would sell those coilovers, especially if they are of the E-bay special variety.

You have quite a few options as far as shock/spring combos. If you are just looking for something to eliminate wheel gap, but arent overly worried about on-track stiffness and performance, you could go with something like the Tokico suspension kit, available at www.shox.com . it runs $379 and includes non adjustable shocks and 1.5" lowering springs.

If you want something that will give you improved performance at the track, id recommend Tokico Illumina adjustable shocks $439 for all 4 corners, and some Eibach Pro-kit springs (1.2" drop around $210)
