On the front of the Cobalt it is controlled in roll by caster which only works while turning. Caster works really well by increasing camber on the outside and decreasing on the inside. Since our wheels are fixed going straight in the rear caster is not helpful. For the Goblin we can add neg camber and raise the rear so that the lower control arm is tilted down from the center of the car going towards the tire. If that makes the ride height too high we can run a shorter tire or wheel tire combo. To keep from going positive camber we can limit wheel travel by rear swaybar , stiffen rear springs or get the roll center closer to the cars cog.
Another problem is that putting a ton of camber in the rear in addition to toe will wear the inside edge of the tires out quickly if you do a lot of street driving.
