Front springs vs. Front weight

[Dirt Knife]

What is the corelation between front weight and front springs.
I understand there is a difference betwen flat track and banked track and the
size of the track.
Runn on a rough IE 5+ corn furrows in the corners and concrete cow pies (speed bumps all the way down the
straghtaways.
Nose weight (1728) ran 1000 RF and 925 LF
felt like the car was shaking apart
pushed so dimond the track to the berm and pushed off that
finished 8th in feature 24 cars 25 laps

Think I need to soften the spring package 2 what ??????????
