Ideal weight distribution
Making the weight on the front tires and the rear tires equal in a turn does not necessarily mean that the weight distribution should be 50/50 (50% front, 50% rear) while the car is standing still. The type of track you plan to drive on determines the ideal weight distribution. If the track requires getting on the throttle early in the turns, then weight will be transferred to the rear of the car while you are in the turn. Therefore, you should add weight to the front of the car to offset the weight transfer when you get on the throttle.
Instead of using a 50/50 distribution, you might want to try 55/45. The front of the car will be heavier than the rear when the car is standing still, but when you accelerate in a turn, weight will shift to the rear and balance the car. If you are driving on a track with short, sharp turns, then you will probably be getting on the throttle late in the turn. Therefore, you want a more even weight distribution to start out with (possibly 51/49) so that the weight will be evenly distributed as you drive through the turn.
Generally, if you are driving on a road coarse with approximately the same number of left and right turns, front bias should be the only weight adjustment that you work with. However, there are two other adjustments that can improve handling if you will be racing on an oval or a track with predominantly right or left turns: left weight bias and cross weight. Left bias is adding weight to the left side of the car so that it will be balanced in left turns. The same can be done for right turns.
