Help me understand...

Yeah, the LCA is tilted just a bit more than the UCA. What would the impact be if I were to rotate the control arms down so the LCA is level? The IC length would remain the same but the the height would be 7 1/4". Would that have an effect on handling at all?

Your side view IC mainly has an effect under braking and caster change in bump and droop. With the limited travel you have available, rotating them shouldn't have a huge effect on overall handling. Leveling the LCA will make the suspension more compliant over bumps (better ride quality).

Keep in mind that those stock control arm angles may likely have had as much to do with packaging as optimal geometry...
