With struts on all 4 corners, you have a near 1:1 motion ratio all around. If we assume say 125 pounds per axle of unsprung weight with your 1200/800 weight distribution, that leaves 1075/675 sprung weight. Combined with your 448/336 spring (and wheel) rates, that leaves you at 2Hz front and 2.2Hz rear. That gets you nicely in the 'flat ride' ballpark, and should inherently need at least some front sway bar but not necessarily a rear bar.
Just using this rough approximation, and depending pretty heavily on your actual sway bar rate(s), you may actually come out pretty good without any rear bar. I'm not sure what the smallest front bar that would bolt in is, nor what the one in your possession (if you have one already) is, but I would suspect there is a good chance that even if after testing you wanted less understeer you could just go with a smaller front bar to get the handling balance where you want it, rather than adding a rear bar.
thanks for the help. i appreciate your efforts and input. Do you think dampening adjustment may also help. They are ISC N1 coilovers with 32way adjustability. My guts tellin me the stiffer rear springs will do fine without the bar. I can go down to a 224# spring in the rear on the same dampers as per ISC tech told me. The buggies got 525hp, and like i mentioned before, a lil understeer may not be bad
