Does anyone have instructions or a tutorial on setting pinion angle?

Pretty sure BMR has one on their site.

I only drive my car on the street and what has worked best for me is setting the rear pinion yoke parallel to the output shaft of the trans. This has given me the least vibration at highway speeds. If you are drag racing, I would set the rear pinion 1 to 2 degrees down from parallel with the trans. Just my opinion though.

Do you set the pinion with the rear suspension unloaded or while it is normally compressed?

Set the pinion when the vehicle is compressed. A drive on lift works the best.

You want your u-joints to be at the same angle and in phase with one another for a street car.

So set the pinion angle to the same angle the transmission is at, is that correct?

I will finish installing my rear this weekend and don't want any vibrations. To eleminate how much a u-joint has to turn would it be bad to set the angle of the rear to the same angle of the drive shaft? in a car the drive shaft should be relatively level at ride height.

Equal but opposite. If your transmission tail shaft is 3° down at its yoke, then the differential yoke should be 3° up. This is easier to do, i think, on a four post lift with the drive shaft off the car. Though I have leveled the car on bottle jacks, and had the drive shaft installed, and was still able to get the angles worked out.

This is more properly called getting your drive line angle. You need to know the angle of one side so you can set the other.
