You may be putting yourself at risk of excessive bump-steer if you lower the rack. The tie rods must be at the same angle as the control arms so they follow the same arc through suspension travel. If you lower the rack to have flatter tie rod angles relative to the control arm angles, you'll drastically change the toe angle as the suspension cycles.

do you have any current pictures of your front suspension components? I'd be amazed if they're not at the same angles... If the tie rods are at a steeper angle then the control arms, then there is benefit to lowering them for that reason as well.
