not sure if there is a swaybar, but that would definately help
im not sure if they make these for the mazdas, but ppl use jointed shackles on one end of the leaf spring rather than a 1peice fixed shackle, provides a lot of articulation
my ranger's stock rear suspension flexed a good amount, there was no rear sway bar, i could tuck one of my 31inch tires out back flexing, it was all stock except for air shocks
