While this will help rear wheel traction, it really compromises the ability of the car to get weight over the front tires on braking and your stopping distances will go way up along with brake wear and heat.

You will never achieve 50/50 balance on a 996tt unless you put around 700 lbs in the trunk. The goal of corner balancing is to get LF+RR = RF+LR. Porsche specs the max difference at 20kg.

Exactly. But imagine how bad it is with the nose jacked up in the air. Corner balancing cures a lot of ills. Most of which can't be discovered with a tape measure on a very stiff suspension.

I am getting some knocking sound when going through some rough road.
