does have anti roll with me in the car it's set in neautral possition. i turned the upper right 4 bar one flat shorter from neautral pulled the wheelie bars up to 4" and does apper that they touch verry little to none checked rollout on tire and thee the same, the length of the lowere bars are the same and the right rear strange shock is one click stiffer on the compression. the car still pulls hard to the right on the line and i have to pull it back over to get it in the grove. after that it tracks staight and brakes straight and safe. scarry ride!
