Default What should my pinion angle be?

I installed an Alston torque arm in my car and I need to set my pinion angle. It's a 6 speed, if that matters. I was thinking 2-3* positive, but I'm not sure on that.

I set it at two degrees positive (pinion pointed down) and it made a huge difference in driveline vibration... before it'd shake the car apart at 110, took it up to 125 after it was done and it was smooth as silk.

It depends on what you've got and what you are after. For mildly modified -1, for high HP cars, -2. Pinion angle should be negative, not positive. For street aps, you do not want to pre-load the drive train too much.
