Look up in the tool box section. There is an article about lead placement that will give you some pointers.

Adding ballast weight behind the center of the rear axle will look good on the scales because of the leverage effect. A certain amount of weight placed far enough behind the "fulcrum" (the rear axle) will actually remove some weight from the front tires, thus giving the appearance, on the scales, that a vast improvement has been made in rear percentage. But, you have to be careful of the pendulum action of weight placed behind the rear axle too. As the car is tossed into a slide entering the turn on a dirt track, all that rear ballast can upset the handling because it is pitching about like a pendulum. Bottom line = place the weight as close to the rear axle as possible and try to keep it as low as possible too. A lot of cars cary their ballast in the left rear section of the rocker panel area.

I know everyone talks about the pendulum effect and they are probably right, but i put my weight as far back as i can get it. I have a lot in the bumper and the bottom side of the frame rail. I also had trouble with carrying to much weight on the left front and not having much crossweight, so i ended up putting weight on the right rear. I also drive a little different than most people, i dont slide into the turns i drive the car in kinda like asphalt. I run on a 1/2 mile high banked dryslick track.

well we like it further back than most and have tried several different ways as of yet dont see a problem with it back towards the rear of car. But who knows we could be wrong but until i see a differents mine will stay further back. One of our top track modified guys run there as far back as possible and i mean he is fast week after week and also track owner.
