Mother Mopar was the first to really science out the leaf spring suspension and they published their findings in their Chassis book.

Standard Leaf Springs 5 to 10 degrees nose down, 5-7 best

Leaf Link 3 to 5 degrees down

4 Link (double pivot) 2 degrees down

Ladder Bar (single pivot) 1 degree down

Note:Front Universal Joint Angle ( all suspensions ) 2.5 degrees or less

I run 6 degrees down on the Max Wedge with the real SS Springs. I'm going to switch to Cal traks this year and I figure it might be prudent to ask them about the angle used with the new springs and traction bars.
