Very good Dave, I have those measuring devices. Is it critical that this is done at ride height, in other words what the measurement would be with all the weight of the car on it? Or is it more of a measurement of stance? In other words since I want the car a little higher in the rear than in the front, this will put the frame at a slight angle. I would need to measure the 5 degrees from that angle right? Sorry if I am being too inquisitive but it is very important to me to get this right. I will be driving this car for a long time.
