RE: torque roll
what I did on mine to eliminate the torque twist all together is I mounted my 2 upper links down in the same location as my lower links on front and rear. you may need to make up some new links to get the length right. what I did was mounted the up to the same bolt that holds the lower on. the uppers on inside of chassis plate and lower links on outside. torque twist gone forever on mine. I also run soft springs in front and med on rear.
