I used to weigh all three wheels, but have stopped. At the moment, I'm only concerned about the weight on the FDW. With the rear weighting, I do not shoot for any specific weight, but rather, whatever weighting works best (no wiggle) with the least amount of steer. You'll find every car likes a slightly different weighting. I did not believe it at first, but after doing this for a bit, I subscribe to that theory. I track will help you see this more readily.
