Thanks for all the info guys. I have a Madjax 6" A-Arm on it now, so the rear already rides like its on cinder blocks. Since its a hunting buggy, I did lower the air pressure on my tires to 8lbs and that has brought some relief to my back and kidney's.
I'm not a speed nut, so will probably only do disc brakes in the rear. I got the torque I needed with a motor and controller upgrade, so now I can get food to my deer. LOL
May have to go with Allsports to keep front track close to OEM.
Thanks again for all the advise and info.
