Another pinion angle ?

I believe the Mopar chassis book says 5-7* down.

Are you using the pinion snubber? Also what tire?

I don't think I will be using the snubber. Found that is a "to each their own" topic.
Tire on the street is up in the air yet but is looking to be a 325/50/15. At the track will be a 275/60/15 Nitto DR.
