One thing you can do is print parts in 2 pieces. Have the layer lines going one way on one part, and perpendicular on the other. This creates a lot more strength in the overall design.
Like for control arms, if you lay them on the bed so the hinge pin holes are going along the Z axis, you will have less change of them delaminating along the hole. But then, any impact to the arm will likely split the arm. So if you design it so the hinge pin bosses bolt onto the structural part of the arms, which would be printed flat on the bed, you end up with a pretty strong arm.
Same goes for the bulkheads. It would be best for the hinge pin holes to be printed vertically, while the area that bolts to the shock tower is designed to print flat on the bed.
It's tough to get some designs to have an ideal orientation on the print bed without compromising the design somewhere else. So that is why I typically split pieces up.
