Caprice/impala stub front spring help

The car is an imca a mod with a claim engine 04 kraft car 4/z , wondering how soft is to soft on the front for these cars? Current springs are LF -750 RF -800 LR-13" 250 RR-11" 200, Ls -54.3%, cross- 53.1% rear- 58% with 25 gallons of methanol. Car pushes on or off throttle, on entry to center then goes loose center off if your aggressive on the throttle. It's not to bad if you back up the corner and the drive off is really good but I'm loosing quite a bit trying to get it to turn.
