these two front swaybars offered are the same diameter, meaning their stiffness differences should come from the holes relative to eachother. id like to know how the adjustable s4 ST front bar's holes compair to the RB to see how their stiffness compairs. if anyone has seen these two swaybars side by side you might know the position of the 2 holes per side on the ST bar as compaired to the racing beat's 1 hole per side. thanks.
