Ben,
There is a tolerance or range which is acceptable for camber. The rear has an offset nut so does have a tiny amount of adjustment, but nothing on the front. If you go beyond 1 inch drop you will need adjustable camber arms front and back to bring it back with tolerance. I found all of this from my350z.com by checking experiences of other spring setups. For non coilover, the best seems to be RS-R, others are Tein and Hotchkis. I got mine with my wheels from the states. They seem to be difficult to get hold of, but try one of the US 350z specialist sites such as 350zonline.com or UltimateZ.com
Hope this helps.
PS: Val, (TheMinel), has now got mine but not yet fitted.
