D. Rear Bars - We are allowing the placement of two rear bars, solely for the purpose of safety. Maximum of any tubing size will be 1 3/4" round, there will be no 3" or 4" channel. The rear bars may extend rear-ward from the top of the cage behind the driver, angling down towards the rear of the trunk area. We suggest having a piece of tubing welded flat on the trunk floor, back near the kick-up of the very rear of the trunk area. This is the material that your two rear bars will attach to. No bars of any kind will extend out through the rear of your trunk area; any bars out past this point will need to be cut out before racing. You may have one "X" in between your two diagonal bars or you may have one horizontal bar going between your two bars; nothing more than that.

Refusal to accept claim will result in all points and monies to be forfeited, and car and driver will not be allowed to compete for eight consecutive races. Penalty can carry over to next season. This rule exists to ensure that car costs continue to stay affordable. Berlin Raceway is not responsible for engine pulling, the driver/team is.When claiming a Motor the claimer must have same engine in their car.
