FUNCTION & FORM TYPE II COILOVERS

these are the wheels that are going on the car.
my build thread =p

i am looking at getting a set of these, i am new to the s2000 scene and coilover scene. I have always had bags, but my s2000 is not a daily and i wanna be as low as the black one up top. I saw he said something about spring preload? what exactly is that and what is the process to do it? like i said i am new and hopefully someone can chime in and help out?
I have FF2's on my AP1 and I like them. The only problem is I just moved and my new driveway isn't as flat as my previous place. My car scrapes from front to back. Luckily, it's not my DD. I'm hoping to find some time this weekend to adjust the height (unfortunately). Not looking forward to it and I might need some help. Any volunteers? lol.
I daily my 2000 Ap1 on these coils with the stiffness maxed out. Definitely liveable. Only complaint i have is that i cant get my car high enough...? My coils are maxed out as high as I can set them and the rears still rub on the outside on large bumps. Bear in mind i'm running 18x9.5's in the back with a +65 for the winter though...
