FC3S Murray's never ending build.

[TitaniumTT]

The benefit will be there regardless of the spring rates being used.... I would think less spring rate would result in a higher benefit from no bar, allows the suspension to flex. If there were no springs, only shocks and you went hard into a turn the inside wheel would lift from the outside wheels compression and the swaybar picking the inner up. So I dunno how much truth there is to what you heard.

FWIW I'm running a 7/5 setup, RB front and no rear and I love it. VERY neutral, slight understeer when I head into a turn too hot or too hard on the brakes.
