Raising the bar hits the tire harder, and increases chassis seperation, lowering the bar hits the tire softer and decreases the seperation. NO matter what , you are never getting rid of the seperation in a ladder bar suspension. THere will always be rise or seperation, thats why you need a GOOD shock with a ladder bar and a lot or decent power. For a daily driver or part time street strip car like this, i would put the bars level and adjust them at a test session depending on what the car does with the power it has.
