Brian,
Would you consider changing the min. weight rule? Right now, the way it is setup it would penalize a lighter driver who might team up with a heavier driver.
Right now for a lighter driver and a heavier driver /kart combination to make weight, we would have to add a lot of weight to meet the min weight rule with the lighter driver on board. Then when the heavier driver gets into the kart to drive, they are at a big disadvantage.
Maybe compromize and do an average weight for the team, IE kart weight + driver #1 weight + driver #2 weight… then divide the total by the number of drivers and work out a fair weight for the package. That would let teams with lighter and heavier drivers minimize the amount of weight and still be competitive.
