Pinion angle

[BUCKET]

What seems to be optimal pinion angle for these cars?

It depends a bit on your bushing types.

Depending on who you ask the pinion angle is the angle of the pinion relative to the Crankshaft Centerline OR the Driveshaft. I prefer the Crankshaft but I have explained both procedures below.

To measure it, you will need an angle finder that has a 360degree face and uses gravity to pull the needle. These usually come with a magnetic base and are about 3-4" in diameter.

~If all the control arms have Factory bushings: Set Pinion Angle 3 degrees to 4 degrees downward.
~If all the control arms have Poly bushings: Set Pinion Angle 2 1/2 degrees to 3 degrees downward.
~If all the control arms have Solid bushings: Set Pinion Angle 1 degrees to 1 ½ degrees downward.

Well that makes sense. I am used to about 2*

If you have a 1-piece DS, it will let you know if your car doesnt like the pinion setting.

My pinion angle is perfect, until I have a passenger or 2, then I feel a slight disturbance in the tranny..... Nothing too horrible, but noticeable.
