Shangrila, tighten that ball diff to full lock and use locktite to keep from loosening. Also put the gear side offset to the right side of the chassis. Put enough orings (probably 3) so arms are level, that should be ballpark setting.
Try red springs front, blue rear. 30 - 40wt oil. Tell us how you do in your race.

p.s. i find the m05 to also have better rotational speed than the m03. smoother around the corners.
