Lowering the mach's nose.

A while back I was considering lowering my car with either the eibach sports or HR super sports. Then I got to thinking about my what I really wanted out of the car as a whole and how I do not want to do any mods more than once if I can help it. Ultimately I think I will wind up going longtubes and procharged and forging the motor. What I want out of a drop is to bring the nose down a bit but still be high enough to get over speedbumps, and a spring that will help get the weight on the back wheels when I nail it. I want to feel it sit down and dig in not slid to the side. I dont really feel the weight go to the back on the stock springs. Now i have been doing some reading and I am thinking maybe going with the FRP C springs. Should leave the rear at the same height and bring the nose down 3/4 of an inch I think. Don't want to cut my stockers in case i decide I dont wanna go back for some reason. After I pick the springs then I'll worry about complementary shocks, arms, etc.

Heres the page I was using to compare rates and drop.

Coil Spring Tech

Am I thinking along the right line here?

Then maybe I misunderstand how they work. The springs are just step one to getting there. I thought a higher rate in the front would help pick the weight off the front during launches and a lower or progressive rate in the back would make it easier to push the tail down at launch. I was thinking about just swapping the fronts out first an trying that for a while before swapping the rears in.
