Using the calculator you originally posted 4.5, 3, 3.5 equals a perfect setup. Working angles of 1.5 and .5.
Even if the drive shaft raised a degree due to resetting the rear it still would have worked, 4.5, 2, 3.5 = 2.5 and 1.5.
Now, using 1.4, I cannot make it work. I think I should have left it alone and fixed the rear end.
