custom made RCA question: what height?

[cj]

NoHachi Wrote:The best way to determine the correct hight, is measuring it. Lower the car to your desired hight and look how much the hub needs to move in order to have the lower control arm perpendicular to the ground.

Measure with the normal # of people in the car and half a tank of gas.

This would give you the best possible negative camber gain.

Does anyone know what is the stock position of the control arms? Are they exactly perpendicular? My car came with some changes in the suspension so i can't use its current status as a criteria for the angle.
