Unless you're running solid differential bushings, you'll still need a tiny amount of angle offset so the joints are in phase when the diff rotates a bit under load. You always dial in a bit less angle on solid axle cars, especially with leaf springs. I imagine an IRS setup would require less, but there's still going to be some movement..
