Adding Weight or ballast in the trunk.

Well I'm here at the trace with my cheeter slick back on, 160 pound of weight in the trunk.
Can all most make it hook but had to raise my air pressure back up to 20 psi because the rim is spinning on the bead.
Good plan but no hook for me. will put screws in the rim for the next street legal race in Aug.
Really thought it would hook and go.......well ok it is .3 quicker with 160 pound of weight.
The weight helped.........just not enough.
o well having fun burning up these old 60' style drag slicks.:D
I used a piece of 2" square tubing i had left over from my subframe connectors. I welded one end shut then filled it with used lead wheel weights I got from the local tire shop (brought them all some coffee!) I pounded the weights in then welded the other end closed. Added some angle iron brackets and bolted to the frame in the trunk. It weighed 100 lbs.
