the problem i have with 3* down, is 3* compared to what? where on the frame do you measure? rocker? door sill? what happens when you put it on jack stands and its not supported by the tires and your rake changes? what happens if you change the stance later?
start with parallel, and if that works and youre working angles are pretty low, leave it. if they are not, you may need to point the pinion down to get your working angles in an acceptable range. although its different than what youre commonly told, most dont run the ride heights that we do.
heres a site to check out. you can download a free trial and input all of your information, and it will tell you where to move what.
