What Are the Purposes for LCA Relocation Brackets?

Straight from the BMR website, has nothing to do with keeping the LCA's level -

Your vehicle's "instant center" determines it's ability to transfer weight upon acceleration for better traction. Move the instant center of your vehicle by changing your control arm angle with BMR Suspension lower control arm relocation brackets. These control arm brackets will allow you to tune in the instant center of your chassis, an essential for racing or lowered vehicles

In a quick:

If you draw an imaginary lines forward following the control arms, the intersection point will be your instant center. In most cases it will almost always be in front of the vehicle. On a stock setup your instant center will be located below your anti squat line. By adding the relocation brackets, this changes your instant center above the anti squat line thus helping plant the rear tires
