i think the issue here with the foam vs rubber is, these arguments were made years ago, ppl knew no better and bought into it. it is not the truth.....go to iic, novak, clevleand, snowbirds, nats....you will see one run foam. if a guy runs 2 runs it is stock and 19 turn, or mod and 19 turn......they then go away.....
in our area foam is going the way og the Dodo....and rubber is coming back. i have been racing offroad, and with the rubber tire talk i may get a new jrxs.....r....but that is a different issue
