General role of thumb

^ I start there and usually ride around for awhile and make any adjustments that I may need remember with a lowered or raised car you have to take that in account. For example since I lowered white a bit I aim them a bit higher but before I make it permanent I drive around to make sure I'm not directly in someone's mirror and not blinding other drivers.
