add. weight placement ?

if you had to add additional weight to a small tire foxbody were would you add it and why ...... and im assuming its going to be 75-100lbs

If you are going to run at multiple weights we like to add it on the transmission tunnel at little back from the driver. If it is permanent weight then wait until you scale the car and add it where it needs to be to help your weight percentages.

as low as possible i assume ......

We've always had to add between 200-400lbs to make weight.

Locations:
Front bumper area
Rear bumper area
On trans tunnel next to and behind driver
Floor board behind driver and behind passenger seat.

And a majority went on a chassis bar between the old shock mount location in the rear.
