I hope there is no confusion here.
The people who run spec mustang or high sprung coilovers, they have way high of a spring rate that can compensate for the loss of rear sway bar.
Rule of thumb when it comes to the rear mustang suspension:
High spring rate ===> small sway bar or sometimes no sway bar
Stock spring rate and square setup===> smaller than 25mm rsb (stock).
And my above post was describing testing the theory of what rsb size would give the best results for me. Best results will be faster lap times and more balanced car.
