How much rear weight % is to much. I have a limited late model with 53% rear and need to add 150 pounds to make legal weight. I can probably get this car to 57 to 58% by putting the 150 pounds in the right place but I don't want to go overboard. Any help will be appreciated.

WE HAVE A WEIGHT LIMIT TOO. ITS 2400LBS. TO GET TO THAT MOST OF THE CARS END UP AT 57 TO 58% REAR. IT SEEMS TO BE OK, BUT THE PROBLEM IS YOU HAVE TO WORK WITH IT ON THE SCALES OR YOU END UP WITH ALOT OF LEFT SIDE WEIGHT.GOOD LUCK.

The question is, how is the car at 53% rear. If you have to add weight, know what the chassis needs first. Adding Rear % will do two adjustments, it will tighten you in and tighten you off.

Hope this helps,

The car is awsome right now, I would like to add the weight and not change a thing. My guess would be to put the wieght in as much of a neutral place as possible. The car is a 3 link with a 9" with w5 hubs. I have a newly developed traction device that utilizes the rotation of the rear end housing
with a double pull spring bar that is hooked to a birdcage mounted over the center of the housing with a link running to the rear. The forward bite is so awsome, I think that I could get away with less rear %. The question of the week is where is the best place to locaate the ballast w/o changing anything but the total weight.

Artie,
Sorry about the repeat but I would put the weight in the center unless your spinning your tires then on the back.

As far as I have ever been taught and learned with my car, if it is awesome at 53% tail weight, add the needed weight to the center of the car as low as you can put it. My car builder suggests placing the ballast on the "X" in the middle of the frame. This will keep the center of gravity and roll center closer than adding anywhere else on your car. Also, as said in a previous post, adding tail weight tightens you in and out of the corner. Best of luck!!!
