For the sake of clarity......................the overall heighth of the spring as wound is 1" shorter (as opposed to the total length of the wire that forms the spring). In theory, you could accomplish the same thing by cutting enough of a coil (or more) to shorten the overall heighth of your stock coil by an inch. The difference is, by cutting the stock spring you're removing some of the "spring", conceivably making it softer. But there are also springs out there that are wound to be "progressive" (usually identifiable by some of the coils being wound "tighter" than others on the same spring), and if you remover the "softer" end, you end up with a firmer (overall) spring rate. Getting a spring that is wound 1" shorter allows you to get the lower ride without changing the spring rate, thus maintaining close to the same ride you had before modification. Assuming of course that's what you want. The boy racer types will sometimes want a stiffer spring, as well as lower, assuming that will give better cornering performance. Which it may or may not do, since cornering dynamics are controlled by more factors than just spring rate.

As for the camber, with unequal length control arms you get a different arc at the ball joint end which helps control the amount of camber change. There will still be some, but it should be minimized. However, there are limits, as some of us have seen when some one uses air or hydraulic suspension. The further the arms arc, the more camber is affected.
