Saw this pic in ur thread



Seems like u got some serious roll there. And u got the springs on the rear in their original position wich means the motion ratio on the spring is like 0.5. Wich means if u use 500lbs they actually only "deliver" 250lbs. But I think u already know this Install the coiloverkit u removed in the beginning of the thread and test it just for fun. I belive that will work alot better on the track
