upper a arm angles

[racing_kid]

My car has the 3 piece upper control arms and the front has one adjustment hole and the back has two. My question is should I have the back in the top or bottom hole and why? Trying to keep learning and fill my note book up!

The adjustments will add anti dive and pro dive to the front end. Anti dive is where the back point is lower than the front this will resist the car from diving over on that side while on the brakes. If you move the rear point higher it will be the opposite called pro dive. Also moving them up or down together will change your roll center
