Well dude some people do things differently on the front, and you have the option of an adjustable beam, or drop spindles, the spindles will only drop your front about 2.5" but with a beam you can wind the front end down to the ground, If you plan on doing this you maybe best to get a narrowed beam 2" or something, as to give you enough clearance.
You can always fit an adjustable beam, wind it down half way and then fit drop spindles. This will keep your ride soft.
With the rears, these are on splines. What you have to do is make sure your front is where you want it then remove the stopper plate thingy on the back think you need to take rear arches off as when you pull the rod out the spline thingy the arch is in the way, then you just fit it back however many splines lower to match the front, you might need to do this a couple of times to get the correct ride height. Im sure its roughly the same as what alot of people do with the Saxo's, 205's, Clios, I think.
