it's fairly benign on the car, the worst thing that sometimes happens is tires have a tendency to de-bead themselves. if you push too hard into a soft dirt section. (which east bay does not have) plus east bay has compressed air I think, if not a trip down to 7-11 for hairspray and a lighter can re-seat most beads. (just don't have fix-a-flat in the tire kaboom)

To be honest your first time on dirt you are not going to be competitive with the top runners. and, the lack of compliance is not helpful on the slippery stuff so I don't see it being a competitive advantage. now a welded diff, or super off road tires...... that I might have a problem with.. Remember we run a strict No-whining policy. If there is a mis-classed car I'll bump them otherwise if someone protests over something stupid they will be laughed at.

As a wise man once said.. "If you were at the drivers meeting you'd realize this is NOT the SCCA"
