From the factory I think the amount of negative rear camber was ok but could be better. After you lower the car I think to maintain good rear traction under acceleration you would want the rear tires to be flatter(0 camber). You have to look at the arms in your suspension and compare where they are resting now compared to when the stock springs where installed. Then think of the arc motion of those arms and how they would change which way the tire would move if the suspension compressed or expanded. Im refering to the camber curve. It appears our camber moves about .2* the first inch then .2* in the next 1/3 of an inch in our cars rear suspension. so the lower you go the more aggressive the camber gain becomes. for better tire wear and the same aggressive camber you don't need to start at such high negative camber numbers as the stock suspension and still get the same if not better gain. Stiffer springs will reduce the amount of travel but the suspension is traveling in a more aggressive part of the curve.

These show the before and after of the pro kit compared to the sportline kit. If you think about the camber arc movement you can see what I mean by the cambers from the factory are set to a certain degree then they account for a number of inches usually 3 for camber gain on a stock car for a sports car it may be higher. After lowering it you are in a steeper part of the curve. the rear seems to have a slightly more aggressive curve than the front but both dont need to be as negative as the factory recommends unless you are going for performance purposes.
